Abstract:

The manufacturing industry remains a critical force in the quest for global sustainability. An increasing number of companies are modifying their operations in favor of more sustainable practices. It is hugely important that manufacturers, irrespective of the subsector they belong to, or their organizational size, implement practices that reduce or eliminate negative environmental, social and economic impacts generated by their manufacturing operations. Consequently, scholars have called for additional studies concerning sustainable manufacturing practices, not only to address the paucity of related literature, but also to contribute to practitioners’ understanding of how to incorporate sustainability into their operations. However, apart from expanding the knowledge of sustainable manufacturing practices, it is first key to understand the ground set of values, or principles, behind sustainable manufacturing operations. For that reason, the purpose of this thesis is to contribute to the existing body of knowledge regarding sustainable manufacturing principles and practices. The results presented in this thesis are based on three studies: a systematic literature review exploring sustainability principles applicable to manufacturing settings, and two empirical studies addressing sustainable manufacturing practices. In general, it is concluded from the literature that there is a little knowledge about sustainability principles from a manufacturing perspective. In relation to the most common sustainable manufacturing practices, it is concluded that these practices mainly refer to energy and material management, and waste management. Similarly, the study of the adherence of sustainable manufacturing practices to sustainable production principles concluded that the principles concerning energy and materials conservation, and waste management were found to create the highest number of practices. Although most manufacturers still engage in reactive sustainable manufacturing practices driven by regulatory and market pressures, some industrial sectors were found to be more prone to develop proactive sustainable manufacturing strategies than others. Furthermore, SMEs were found to lag behind large organizations regarding adherence to sustainable manufacturing principles.

Abstract:

Efficient use of resources and utility is the key to reduce the price of the commodities produced in any industry. This in turn would lead to reduced price of the commodity which is the key to success. Sustainability involves integration of all the three dimensions: environmental, economic and social. Sustainable manufacturing involves the use of sustainable processes and systems to produce better sustainable products. These products will be more attractive, and the industry will know more about the climate impact from their production. Manufacturing companies use a considerable amount of energy in their production processes. One important area to understand the sustainability level at these types of industries is to study this energy use. The present work studies energy use in a large-scale tool manufacturing company in Sweden. Value Stream Mapping method is implemented for the purpose of mapping the energy use in the different operations. To complement this, an energy audit has been conducted, which is a method that include a study and analysis of a facility, indicating possible areas of improvements by reducing energy use and saving energy costs. This presents an opportunity for the company to implement energy efficiency measures, thus generating positive impacts through budget savings. Less energy use is also good for the environment resulting in less greenhouse gas emissions level. This also helps in long-term strategic planning and initiatives to assess the required needs and stabilize energy use for the long run. Social sustainability completes the triad along with environmental and economic sustainability. In this study, the latter is reflected with the company’s relationship with its working professionals, communities and society.

In this study, the social sustainability is reflected with the company’s relationship with its working professionals by conducting a survey. The sustainable manufacturing potential found in the case study indicates that significant progress can be made in the three sustainability dimensions. Although, the scope of the thesis is limited to a tool manufacturing company, several of the findings could be implemented in other tool companies as well as industries belonging to other sectors.

Abstract:

At 2009 rates of disposal, there are only 8 years of remaining landfill capacity at permitted sites in England and Wales. Industry – encouraged by financial penalties from the Government – faces the challenges of cleaner and more sustainable production whilst trying to remain competitive in the market place. This thesis presents development of several theoretical propositions: a ‘fit thinking’ design framework, the ‘All Seeing Eye of Business’ (All-SEB) and the ‘waste alchemist’ industrial role. The ALL-SEB is a model to understand the impact and potential uses of manufacturing waste. The insights provided by the All-SEB model, resulted in a general waste elimination framework developed to serve as a guiding strategy for waste elimination. The main objective of this study was to investigate a major hypothesis derived from the All-SEB: unavoidable waste could be transmuted into profitable co-products as a measure to divert waste from landfill. The ATM (analyse, transform and market) methodology was developed as a way to help companies transmute waste into ‘co-products’. A tool for idea generation (the wheel of waste) was developed to be used in the Analysis phase of the ATM methodology. Case study research was undertaken in order to test the ATM methodology and the way in which unavoidable waste could be transmuted into a profitable co-product in a real world manufacturing setting. The case study results revealed the generative mechanisms that enable waste transmutation into profitable co-products; based on these findings a refined ATM methodology for waste transmutation was proposed. The implementation of the theoretical propositions in industrial settings shed light into strategic aspects of resource efficiency: from waste prevention through ‘fit thinking’, to manufacturing process innovation all the way to a better company integration into the industrial ecosystem. Companies looking to achieve zero waste to landfill status would benefit from using the refined ATM methodology. It was found that the ATM methodology and the wheel of waste are useful to several other actors in the industrial ecosystem: waste management companies looking to transform themselves into ‘resource and energy providers’, to external consultants and to third party companies dubbed ‘waste alchemists’ that could offer waste transmutation services to manufacturers.

Abstract:

This study focuses on different manufacturing processes and material choices for products that are designed to help the future to be more sustainable. These products were developed in a global project that explored the field and subfields of urban mining. This thesis is a part of that project and is meant to come with valuable input to the results. In this urban mining project two products were developed. The two different products that has been developed during this project is the NIX and the UM Factory. They work together with keeping material on the construction site when space is limited in order to reduce the transportation, both for the environmental benefit and also from a cost perspective. Together they will not only keep the material on the site but also refine them so they can be used again. This thesis will look into how these two products can be manufactured and what materials is a suitable choice for the products. These two factors were also thought about during the development of the products, both how to make it as simple design that was easy to produce while still fulfilling the requirements set. Also what materials might be a suitable choice for different parts of the products is considered, in order to be reliable, easy to work with, and relatively cheap. The study also explored some methods and materials that might be worth looking into in a few years. Methods and materials that today are undeveloped or not economically viable.

Energy management in industrial facilities is becoming increasingly popular as firms attempt to become more environmentally responsible and reduce cost by improving operational efficiency. Raytheon is a leader in their industry in energy management, and they view the initiative as a way to become more competitive along with being environmentally responsible. The goal of this project was to develop a framework for achieving sustainable cost reduction in production operations through energy efficiency. The energy efficiency framework will build off the existing lean and six sigma tools and philosophies in an attempt to accelerate acceptance and deployment by using a common language and proven methods in the company and industry. A 1.6 million square foot manufacturing facility at Raytheon IDS consumed $13 million of energy (90% electric) in 2010, 75% of which was consumed directly by production equipment. The equipment is diffuse, highly specialized, and used in "high mix, low volume" manufacturing. The challenge with improving production energy efficiency in this environment is that it requires a combination of technology improvements, processes modifications, and changes in the way employees conduct their work every day. The project's success relied on cross-functional (i.e., operations, engineering, and facilities) engagement from senior management to front-line operators. To sustain results, energy performance metrics were designed to keep production area leaders engaged and allow management to set progressive goals over time and reward success. The proposed metrics use a combination of tracked energy use and a "best practice" scorecard that promotes proactive engagement. Lean "Energy Gemba Walks" were initiated to generate and manage best practices and to share knowledge among production areas. The implementation phase of the pilot project (October and November 2011) resulted in an 18% energy reduction compared with the average for the year. Meanwhile, production output and total labor hours were up 18% and 11%, respectively, during the pilot, while the product mix remained constant throughout the year. The improvements, if sustained, correspond to a $74,000 per year cost savings in the pilot area.

Abstract:

La révolution la plus récente dans l'industrie (révolution industrielle 4.0) nécessite une plus grande flexibilité, agilité et efficacité dans l'utilisation des équipements de production. Le système manufacturier cellulaire dynamique (DCMS) est l'un des meilleurs systèmes de production qui répondent à ces exigences. En outre, l'importance croissante du développement durable force les fabricants et les gestionnaires à prendre en compte les enjeux environnementaux et sociaux dans la conception et la configuration des systèmes de fabrication. Cette thèse porte sur la configuration durable des DCMS en proposant trois modèles mathématiques. Le plus grand challenge de cette étude est (i) de choisir des critères sociaux et environnementaux appropriés, (ii) de les intégrer dans des modèles mathématiques et (iii) d'étudier l'impact de ces critères sur des DCMS. Le premier modèle est bi-objectif afin de faire un compromis entre certains critères sociaux (offres d'emplois, risques de la machine, etc.) et économiques (divers coûts liés à la formation de cellules). Pour être plus proche de situations de la vie réelle, certains paramètres tels que la demande, les coûts liés aux machines et la capacité en temps des machines sont considérés comme incertains. Pour résoudre ce problème, une méthode d'optimisation robuste est appliquée pour faire face à cette incertitude. Dans le deuxième modèle, toutes les dimensions du développement durable sont prises en compte dans le modèle mathématique bi-objectif proposé. La première fonction objectif modélise des critères économiques (coûts) et la seconde des aspects environnementaux (déchets de production), tandis que certaines contraintes représentent des questions sociales (principalement le « Daily Noise » à cause de la complexité de calcul). En raison de la NP-difficulté du problème, une nouvelle approche novatrice appelée NSGA II-MOSA est proposée. Le troisième modèle proposé a trois fonctions objectif, une pour chaque type d’enjeux : environnemental, social et économique. Afin d'être proche de la vie réelle, certains paramètres du modèle sont exprimés en termes de valeur floue. Nous proposons une méthode possibiliste hybride pour faire face à l'incertitude et une approche floue interactive est considérée pour résoudre un modèle multi-objectif déterministe pour des solutions de compromis. Enfin, la dernière partie de la thèse étudie la possibilité d'appliquer les trois modèles proposés à l’industrie grâce à une méthode plus facile. Une approche d'optimisation-simulation innovante est introduite pour faire face à la configuration de DCMS : (i) La phase d'optimisation fonctionne comme méthode de fractionnement de scénarii pour réduire le nombre de configurations alternatives en se concentrant sur les niveaux stratégique et tactique. (ii) Ensuite, un outil de simulation détaille le niveau opérationnel en étudiant la performance de chaque alternative et l'interaction entre plusieurs composants de cellules
The most recent revolution in industry (Industrial Revolution 4.0) requires increased flexibility, agility and efficiency in the use of production equipment. Dynamic Cellular Manufacturing System (DCMS) is one of the best production systems to meet such requirements. In addition, the increasing importance of sustainable development forces manufacturers and managers to take account of the environmental and social issues in the design and configuration of manufacturing systems. This thesis focuses on the sustainable configuration of DCMS by proposing three mathematical models. The main challenge of this study is to (i) choose appropriate social and environmental criteria, (ii) integrate them in mathematical models, and (iii) study the impact of these criteria on DCMS. The first model is bi-objective in order to make a trade-off between some social (job opportunity, potential machine hazards, etc.) and economic (various costs related to cell formation) criteria. To get closer to real-life situations, some parameters such as demand, machine-related costs and time capacity of the machines are considered as uncertain. To solve this problem, a robust optimization method is applied to cope with this uncertainty. In the second model, all dimensions of sustainable development are taken into account in a new bi-objective mathematical model. The first objective function models economic criteria (costs) and the second one environmental aspects (production waste), while social issues (mainly Daily Noise Dosage because of computational complexity) are modeled as constraints. Due to the NP-hardness of the problem, a new innovative approach called NSGA II-MOSA is proposed. The last model has three objective functions, one for each dimension of the sustainable development: environmental, social and economic. In order to be close to real life, some parameters of the model are expressed in terms of fuzzy value. We propose a hybridized possibilistic method to deal with uncertainty and an interactive fuzzy approach is considered to solve an auxiliary crisp multi-objective model in order to find trade-off solutions. Finally, the last part of the thesis studies the possibility to apply the three proposed models to the industry thanks to an easier method. A novel optimization-simulation approach is introduced to deal with the configuration of DCMS: (i) the optimization phase operates as scenario fraction method in order to reduce the number of alternative configurations by focusing on strategic and tactical levels; (ii) next, a simulation tool investigates the operational level by studying the performance of each alternative and the interaction between several components of the cells

Abstract:

The financial and environmental costs associated with the manufacture and consumption of products may be reduced through design for efficient production, service life extension and post-consumer value recovery. In response to today’s need to design with consideration for the whole product life cycle, British Standards Institution (BSI) published BS 8887-1 (2006) Design for Manufacture, Assembly, Disassembly and End-of-life processing (MADE). Original research into the distribution and use of this first part of the MADE series is reported in this thesis. The organizations that accessed BS 8887-1 were categorised using their Standard Industrial Classification (SIC) code. The results are presented graphically in multilevel charts using the hierarchical structure of the SIC system. The study found that the majority of standards users that purchased or downloaded BS 8887-1 were companies in the manufacturing sector and particularly electronics producers. Educational institutions also showed high levels of interest in the standard. For the first time, the use of BS 8887-1 in practice has been investigated. The purpose was to discover if, why and how it is being used and to identify examples of its application in design practice. This was accomplished through semi-structured interviews with design practitioners from both industry and academia, thus helping to explain the results of the earlier SIC study. The information gathered through the interviews shows how BS 8887-1 has informed the design process and how it has been used in combination with various design and management techniques e.g. Advanced Product Quality Planning (APQP). These studies suggest that demand for the standard has been stimulated by the introduction of Extended Producer Responsibility (EPR) legislation, especially the Waste Electrical and Electronic Equipment (WEEE) directive. Importantly, the use of BS 8887-1 has been found to be helpful in winning new business and reducing the costs associated with manufacture, product maintenance and waste management. Based on the result of the qualitative research, a new model of the use of standards in the New Product Development (NPD) process is presented. The research was proposed by the Chairman of the BSI technical committee responsible for the BS 8887 series. The beneficiaries are BSI, industry and academia, since the investigation has shown BS 8887-1 to be of value, and has informed the continuing development of this series of standards. The thesis concludes by arguing for BS 8887 to become the basis of an International Organization for Standardization (ISO) standard in order to reach a wider audience. It also identifies a need for the standard’s design requirements to be supported with additional supplementary interpretation expanding on, and adding detail to, the information in the standard itself. Influenced by this research, at the time of writing a new BSI working group was being formed to consider developing BS 8887 as an ISO standard. BSI had also begun the process of commissioning a handbook to assist designers in the practical application of BS 8887 in industrial design.

Abstract:

Environmental considerations have led to the phase out of chlorofluorocarbon (CFC) refrigerants from the domestic refrigeration industry. One intriguing aspect is that the chlorine in CFCs is a good lubricating agent and any deterioration of system performance may adversely influence other environmental considerations. Based on the above, the aim of this research is to address the sustainable development of domestic refrigeration systems using the replacement refrigerant HFC-134a. The work focuses on the emissions that may arise if the electrical consumption of the product deteriorates or its durability is curtailed. Tribological characteristics on compressor components influence both of these product attributes and therefore a thorough system analysis was carried out. An in-house built experimental test rig, which monitored slight variations in the electrical power drawn by a reciprocating hermetic compressor, was used under different experimental conditions. Furthermore, a detailed life cycle assessment on a domestic refrigerator was performed to help quantify the ensuing environmental burdens. In this way, a relation between tribological characteristics, power consumption and environmental impact was studied. Results have shown that the CFC substitute will increase friction and wear characteristics on the aluminium alloy connecting rod and the steel gudgeon pin. These characteristics led to an increase in the electrical energy consumption of the compressor such that the indirect global warming implications are set to rise with HFC-134a. If the sustainable development of this product is to be ascertained then a change in refrigerants alone will not suffice. New design considerations, primarily aimed at servicing and extending the life of the hermetic compressor itself, are considered. This work helps stimulate new ideas to address environmental issues influenced by traditional engineering disciplines. For this reason additional future research work, which will help determine these implications further, is outlined.

Abstract:

International environmental concern led to the control and phase out of traditional chlorofluorocarbon refrigerants (CFCs) under the terms of the Montreal protocol. CFCs used in domestic applications were initially replaced with hydrofluorocarbons (HFCs) such as R134a which has a zero ozone depletion potential (ODP). The use of HFCs has also come under scrutiny as they have high global warming potential (GWP) and inferior thermodynamic and lubricating properties and have been replaced by hydrocarbon (HC) refrigerants such as R600a in much of the domestic European and Asian markets. Despite this, there has been little research into the long-term environmental consequences of their application. Domestic refrigeration compressors were analysed to ascertain the tribological contact conditions for both R600a and R134a systems. A novel pressurised micro-friction test machine was developed to simulate the tribological conditions of the critical components using aluminium on steel samples. Refrigerant charges of R600a with mineral oil (MO) and poly-ol-ester (POE) lubricant and R 134a with POE were tested for their tribological performance within the test rig. Experimental tribological information is presented from the physical test procedures to establish wear mechanisms and friction coefficients within the critical components. The tribological performance is used to predict deterioration in energy consumption and system durability. Results indicate that for higher contact stresses R600a MO charges provide a lower wear regime than R600a and R134a POE charges. At lower contact stresses the R600a and R134a POE charges provide a very low wear, very low friction regime. Despite contact conditions lead to a faster deterioration in durability, hence increase in energy consumption compared to the R600a system.

Abstract:

During the last ten years the small manufacturing enterprises (SMEs) sector has become firmly established at the top of the development agenda for many countries, hence, marking this sector's increasingly acknowledged economic importance. Evidence from various parts of the world has shown clear signs of the growth of SMEs. Despite this, little attention has been given to understanding the environmental impacts these enterprises produce or to defining the role these entities play in terms of sustainable regional development. This thesis sets out to contribute to a better understanding of the influence of SMEs on sustainable regional development, as well as the contribution of SMEs to the economy in terms of job creation in the context of developing countries using Egypt and its Ismailia region as the basis for case study. Three main hypotheses were formulated relevant to the role of SMEs in sustainable regional development. In general, these hypotheses relate to the following: 1) The contribution of SMEs to the regional economy; 2) Problems and barriers SMEs face in achieving sustainable development; and 3) The potential for SMEs to utilize available existing resources to enhance their role in achieving sustainable regional development. In order to test these three hypotheses and to answer related questions, an analysis was undertaken within the framework of two spatial tiers: national and regional, that is Egypt and Ismailia, respectively. Two types of data were used - primary and secondary. A sample of 101 entrepreneurs and 100 workers were interviewed from the Ismailia region. The results of these interviews were analyzed in the empirical portions of this thesis. Chapter one pertains to the justification of the thesis; its objectives; the development of related research questions and hypotheses; the methodology used for data analysis; data sources used; questionnaire design; survey methods; and problems of data collection. Chapter two discusses the concept of SMEs worldwide and in Egypt as a basis from which to provide a concrete definition of SMEs that is used in the empirical portion of this study. In addition, the potential of SMEs and the problems facing SMEs in terms of sustainable regional development, the differences between SMEs and larger enterprises, as well as the importance of SMEs for the Egyptian economy are discussed in this chapter. The relationship between SMEs and sustainable urban and regional development is highlighted in more detail in chapter three. This relationship is discussed within the context of the notions of the overall concept of sustainable development, the sustainable regional development agenda in Egypt and related regulations, and the positive characteristics SMEs need in order to bring sustainable urban and regional development to fruition. Chapter four examines the first hypothesis of this study; this hypothesis states that, in general, SMEs have a positive effect on the economic and social development of a region. This chapter evaluates the ability of SMEs to drive the regional and national chains of economic added value; the capability of SMEs to create job opportunities at the regional level; and the effects of SMEs in terms of improved life-style and standard of living of workers and their families. Chapter five tests the second hypothesis in this thesis which states that the affects of a variety of types and sizes of SMEs on regional sustainable development is limited, at least for the time being. This chapter provides an analysis of economic, social and environmental obstacles and constraints that SMEs must face on a daily basis to achieve sustainable development in the region. In chapter six the potential by which SMEs can utilize their assets to enhance their contribution to sustainable regional development is evaluated; the potential opportunities available to SMEs to make better use of local raw materials and to drive the chain of economic activity within the Ismailia region were examined. The ability of SMEs to work more efficiently through the use of clusters and networks as a potential strategy is clarified. Chapter Seven presents a compilation of the detailed findings of this thesis along with the lessons that have emerged as a result of the research conducted. A series of policies and recommendations are provided as a means from which to create favourable conditions to encourage SMEs to play a more significant role in the national economy and in subsequent sustainable regional development. From a national perspective, the activities of SMEs are not usually the most serious source of environmental degradation, but, collectively, their sheer numbers may translate into substantial impacts on the eco-system. While the individual SME has financial problems related to the treatment and disposal of its waste, the adoption of an industrial cluster strategy for SMEs can provide an efficient solution to this problem. A cluster should consist of several single enterprises located in close proximity to one another, thereby, improving the ease of and costs associated with the treatment and disposal of environmental wastes. This study advocates the necessity of raising the degree of environmental awareness for organizations, syndicates, unions and societies related to SMEs, as well as entrepreneurs and labourers in their respective domains. Opportunities for raising environmental awareness can be implemented through a series of organized seminars, meetings and workshops designed to motivate individuals and small businesses within the society of SMEs to incorporate an ecological sense and approach into their daily behaviour and practices. A national policy must be adopted in Egypt in order for the SMEs sector to be successful in its contribution to sustainable development. Such policy must be all-inclusive and provide for the technical support of SMEs, financial support to SMEs, environmental support to SMEs, as well as provide overarching legislative support relevant to this particular sector of the business environment.

Abstract:

This thesis investigates the combinatory relationship between sustainable supply chain management (SSCM) and supply chain resilience management (SRES) by developing a new concept of sustainable and resilient supply chain management (SResSCM). Supply chain management has been implemented by organizations for more than three decades and has been developed by integrating different but independent concepts, such as SSCM. Furthermore, organizations also pay attention to business continuity during periods of risk and disruption. Most organizations prepare alternative plans to maintain resilience and SRES was developed to fulfil this strategy. Both SSCM and SRES concepts are important for organizations in order to improve supply chain performance, and are linked in many ways. However, our knowledge is lacking on the combinatory relationship and effects of these two elements as little empirical research has previously been done. This thesis undertakes such empirical research by applying a three-phase, mixed-methods approach: semi-structured interviews to inductively confirm the combination of these two independent concepts, a survey of Thai manufacturers in the electronic/electrical and automotive sectors, and post-survey structured interviews to validate the survey findings. Thailand was chosen as the context for the study as it is a major manufacturing nation for western customers. The research found interconnections between SSCM and SRES from the practitioners’ perspectives which enabled the theoretical development of a ‘House of SResSCM’ framework that organizations around the world can apply. This thesis also contributes theoretically by providing measurement scales of SResSCM practices to assess and define current levels of adoption SSCM and SRES, which supply chain managers can implement in their organization to improve current practices. Finally, the Thai Government could use this study to support Thai manufacturing and provide direction for supply chains to become more sustainable and resilient.

Calvo, Carrascal Miguel Angel. "Sustainable manufacturing of next generation building materials using microwave energy." Thesis, University of Nottingham, 2018. http://eprints.nottingham.ac.uk/55508/.

Abstract:

Global warming and the high energy demands of fossil fuel in industries have led governments to implement legislation aimed towards developing more energy efficient and sustainable processes. In the brickwork industry, the burning of coal and natural gas provides the energy to fire clay bricks in the 900-1200 oC range into high quality building materials. Microwaves powered by renewable energy sources have been suggested as a sustainable alternative to fossil fuels. Microwave heating has been considered a promising technique for the processing of clays due to the potential energy consumption and carbon footprint reductions, and for its volumetric heating nature, which enables the fast and uniform heating of a load. This could result in improving the mechanical properties of the fired products. The aims of this project were to develop an understanding of how microwaves interact with clays in order to show whether they could be used to fire clay-based building materials, and to understand how this could be achieved and the parameters that affect it. The composition of Danish clays was quantified, i.e. quartz, calcite, albite, orthoclase, kaolinite, montmorillonite and muscovite, and their thermal evolution was studied across the firing range. The dielectric properties of clays were measured at 912-2470 MHz and 20-950 oC in order to investigate the microwave/clay interaction, assess the effects of changing composition, temperature, frequency and material's density on their potential for microwave processing, and provide critical information on the design and scale up of this technology. Relating the mineralogy of a material and its evolution during heating to changes on the dielectric property trends, and thus microwave processability, was examined for the first time in this thesis. Insight into the influence of individual components on the potential for microwave heating was gained from an analogous study on clay constituents. While the dielectric constants of clays were found to be relatively stable during heating, their loss factors fluctuated with temperature. Free and physically bound water were the dominant dielectric species near room temperature, while their removal halved the loss factors until 350 oC. Beyond this temperature, a steady increase in the loss factors concurred with the mineral dehydroxylations. The loss factors sharply rose beyond 800 oC due to sintering effects, while calcite decomposition partially counteracted this growth. Montmorillonite and muscovite were the most microwave absorbing mineral species due to their water affinity and interlayer cation content, enabling the microwave treatment of the whole clay. On the other hand, a frequency shift from 2470 MHz to 912 MHz resulted in a loss factors increase. This is mainly due to the frequency shifting towards the dipolar dispersion area of physically bound water and the zone in which ionic conductivity heating effects dominate. Mixing rules were used to relate each single mineral to dielectric property variations, and thus rapidly gain knowledge of the microwave processability of any clay across the firing range based on its composition. Böttcher model provided accurate estimations when compared to experimental measurements, and with the same degree of uncertainties at the 912-2470 MHz frequencies and 0.56-0.37 void fraction ranges. The model was expanded for different compositions with clays from Spain, England and Netherlands. This was the first time that mixing rules were successful in estimating mixtures of more than three constituents. A microwave system was developed with the aim of firing clay products of comparable quality to conventional specimens. The basis of design focused on maximising the thermal uniformity of the clay load. The process design steps involved remodelling the clay load, building heat transfer models of the load, carrying out trials to study whether clays behave as expected from their dielectric properties, i.e. volumetric or selective heating, minimising thermal gradients, and assessing alternative methods for the control of the holding stage. Microwave firing cycles manufactured clays with a thermal uniformity at the height of firing of 1050±55 oC and reduced processing times to < 3 h. This is 92% faster than in brickworks, where conventional samples could not match the heating rates without cracking. High temperature (>800 oC) mineral reactions went unfinished due to the reduced holding time of the microwave treatment (30 min), which resulted in dimmer surface colorations. Enhanced thermal uniformity and reduced time for densification resulted in specimens with a 12% higher compressive strength, 38% larger water absorption and 7% higher void fraction. Clay samples three times as big were fired to gain an insight into the scale up of the technique. A tighter process control and higher reproducibility were reported, which is promising for potentially allowing longer holding times in scaled up processes, but the product quality improvement did not change. Looking into an industrial scale up, further work would be required to assess possible design concepts, and an optimal microwave firing process may require complete redesign of the furnace configuration, where several challenges need to be considered, such as brick arrangement, power availability and applicator size and shape. For the purposes of assessing the possible economic and environmental impact of implementing microwave clay firing at industrial scale, one of the most straightforward designs, i.e. retrofitting of an industrial tunnel kiln for microwave processing, was considered. Although energy expenditures would decrease from 11.6 GJ fuel/h to 6.1 GJ electricity/h when using a microwave system for the same throughput, the higher cost of electricity and microwave equipment over conventional burners made the conventional technique more economically feasible. The substitution of natural gas by electricity powered by green energy sources resulted in carbon footprint reductions of >95%, and agreed with the energy policies of numerous countries and supranational organisations worldwide.

Abstract:

This research focuses on effective decision-making for sustainable manufacturing design and management. The research contributes to the decision-making tools that can enable sustainability analysts to capture the aspects of the economic, environmental and social dimensions into a common framework. The framework will enable the practitioners to conduct a sustainability impact analysis of a real or proposed manufacturing system and use the outcome to support sustainability decision. In the past, the industries had focused more on the economic aspects in gaining and sustaining their competitive positions; this has changed in the recent years following the Brundtland report which centred on incorporating the sustainability of the future generations into our decision for meeting today's needs (Brundtland, 1987). The government regulations and legislation, coupled with the changes in consumers' preference for ethical and environmentally friendly products are other factors that are challenging and changing the way companies, and organisations perceive and drive their competitive goals (Gu et al., 2015). Another challenge is the lack of adequate tools to address the dynamism of the manufacturing environment and the need to balance the business' competitive goal with sustainability requirements. The launch of the Life Cycle Sustainability Analysis (LCSA) framework further emphasised the needs for the integration and analysis of the interdependencies of the three dimensions for effective decision-making and the control of unintended consequences (UNEP, 2011). Various studies have also demonstrated the importance of interdependence impact analysis and integration of the three sustainability dimensions of the product, process and system levels of sustainability (Jayal et al., 2010; Valdivia et al., 2013; Eastwood and Haapala, 2015). Although there are tools capable of assessing the performance of either one or two of the three sustainability dimensions, the tools have not adequately integrated the three dimensions or address the holistic sustainability issues. Hence, this research proposes an approach to provide a solution for successful interdependence impact analysis and trade-off amongst the three sustainability dimensions and enable support for effective decision-making in a manufacturing environment. This novel approach explores and integrates the concepts and principles of the existing sustainability methodologies and frameworks and the simulation modelling construction process into a common descriptive framework for process level assessment. The thesis deploys Delphi study to verify and validate the descriptive framework and demonstrates its applicability in a case study of a real manufacturing system. The results of the research demonstrate the completeness, conciseness, correctness, clarity and applicability of the descriptive framework. Thus, the outcome of this research is a simulation-based impact analysis framework which provides a new way for sustainability practitioners to build an integrated and holistic computer simulation model of a real system, capable of assessing both production and sustainability performance of a dynamic manufacturing system.

Abstract:

Climate mitigation, more stringent regulations, rising energy costs, and sustainable manufacturing are pushing researchers to focus on energy efficiency, energy flexibility, and implementation of renewable energy sources in manufacturing systems. This thesis aims to analyze the main works proposed regarding these hot topics, and to fill the gaps in the literature. First, a detailed literature review is proposed. Works regarding energy efficiency in different manufacturing levels, in the assembly line, energy saving policies, and the implementation of renewable energy sources are analyzed. Then, trying to fill the gaps in the literature, different topics are analyzed more in depth. In the single machine context, a mathematical model aiming to align the manufacturing power required to a renewable energy supply in order to obtain the maximum profit is developed. The model is applied to a single work center powered by the electric grid and by a photovoltaic system; afterwards, energy storage is also added to the power system. Analyzing the job shop context, switch off policies implementing workload approach and scheduling considering variable speed of the machines and power constraints are proposed. The direct and indirect workloads of the machines are considered to support the switch on/off decisions. A simulation model is developed to test the proposed policies compared to others presented in the literature. Regarding the job shop scheduling, a fixed and variable power constraints are considered, assuming the minimization of the makespan as the objective function. Studying the factory level, a mathematical model to design a flow line considering the possibility of using switch-off policies is developed. The design model for production lines includes a targeted imbalance among the workstations to allow for defined idle time. Finally, the main findings, results, and the future directions and challenges are presented.

Abstract:

The U.N. projects the world population to reach nearly 10 billion people by 2050, which will cause demand for manufactured goods to reach unforeseen levels. In order for us to produce the goods to support an equitable future, the methods in which we manufacture those goods must radically change. The emerging Circular Economy (CE) concept for production systems has promised to drastically increase economic/business value by significantly reducing the world’s resource consumption and negative environmental impacts. However, CE is inherently limited because of its emphasis on recycling and reuse of materials. CE does not address the holistic changes needed across all of the fundamental elements of manufacturing: products, processes, and systems. Therefore, a paradigm shift is required for moving from sustainment to sustainability to “produce more with less” through smart, innovative and transformative convergent manufacturing approaches rooted in redesigning next generation manufacturing infrastructure. This PhD research proposes the Helical Economy (HE) concept as a novel extension to CE. The proposed HE concepts shift the CE’s status quo paradigm away from post-use recovery for recycling and reuse and towards redesigning manufacturing infrastructure at product, process, and system levels, while leveraging IoT-enabled data infrastructures and an upskilled workforce. This research starts with the conceptual overview and a framework for implementing HE in the discrete product manufacturing domain by establishing the future state vision of the Helical Economy Manufacturing Method (HEMM). The work then analyzes two components of the framework in detail: designing next-generation products and next-generation IoT-enabled data infrastructures. The major research problems that need to be solved in these subcomponents are identified in order to make near-term progress towards the HEMM. The work then proceeds with the development and discussion of initial methods for addressing these challenges. Each method is demonstrated using an illustrative industry example. Collectively, this initial work establishes the foundational body of knowledge for the HE and the HEMM, provides implementation methods at the product and IoT-enabled data infrastructure levels, and it shows a great potential for HE’s ability to create and maximize sustainable value, optimize resource consumption, and ensure continued technological progress with significant economic growth and innovation. This research work then presents an outlook on the future work needed, as well as calls for industry to support the continued refinement and development of the HEMM through relevant prototype development and subsequent applications.

Abstract:

This thesis was conducted in the field of Environmental technology for the Sustainability & Technology Assessment group, at Singapore Institute of Manufacturing Technology. Singapore Institute of Manufacturing Technology is a research institute, striving to contribute to Singapore’s industrial capital through use-inspired research. The manufacturing industry contributes to a significant portion of the world´s total energy and resource consumption. This resource consumption could be reduced significantly through sustainable initiatives and technologies already available today. The reasons why companies choose not to invest in such technologies are often not due to technical factors, but rather due to financial factors. Financial barriers exist because investments are made on the basis of cost based value systems, which seldom justify investments in sustainable technology. When investments are made, the primary reason is to reduce costs while intangible benefits are ignored. However, this study shows that sustainability creates intangible value that current value systems cannot account for. Understanding the true value of sustainability would help decision makers realize that sustainable manufacturing is a viable business opportunity. This thesis studies the effect sustainable attributes has on a company’s ability to generate value. A value system is proposed, linking 40 sustainable attributes to value domains of intangible value. The value of sustainable attributes is quantified using the Sustainable Value approach. The study shows that social indicators, deemed by others to be unsuitable, can be used when proper adjustments to the Sustainable Value approach are made. A case study was performed on the Swedish manufacturing company Finess Hygiene AB to investigate the applicability of the model. The case study showed that the value system was applicable using data that already exists within the company, but the main challenge lies in collecting good and reliable benchmark data. Benchmark data is significantly easier to obtain in Sweden than Singapore for users wishing to apply the proposed value system. A follow up study should be performed to study the potential of a large scale adoption of the value system in Singapore.

Abstract:

With global advances in technology, many organizations are finding it difficult and quite challenging to do business as usual. Japanese companies are on top of the world economy, while many Western companies are struggling to find ways to compete with them (Womack, et al., 1990). The Japanese secret weapon “Lean Production” is no longer a secret; more and more western companies are now learning and adopting Lean techniques to remain relevant and competitive. Lean management is a consistent philosophy and a set of practices that must be maintained over time in order to see the gains (Losonci & Demeter, 2013). Lean is not a quick fix to reduce costs, but a continuous improvement journey that will transform an organization into a cost efficient value-driven system. Lean is still a fairly new phenomenon in South Africa, particularly in the Eastern Cape. The road towards the lean implementation is viewed by many as a challenging and yet rewarding journey. South African organizations are following the trend of implementing lean in order to eliminate waste, improve quality, speed, customer satisfaction and thereby increasing profits. It is however still a long journey towards achieving total perfection. The main challenge facing South African organizations is the ability to sustain the lean improvements over a longer period. This study will focus on identifying and analyzing the main barriers that inhibit many successful organizations from sustaining lean improvement efforts.

Abstract:

Supply chain practitioners in developing economies, like Nigeria, experience challenges in implementing sustainable supply chain management practices. Poor sustainability implementation engenders the negative effects of supply chain operations on people, the environment, and business continuity. The purpose of this qualitative transcendental phenomenological study was to explore and describe the experiences of supply chain practitioners in the consumer goods manufacturing industry in Nigeria about sustainable supply chain management based on the theoretical foundations of stakeholder and general systems theories. The focus of the research question was to examine the experiences of supply chain practitioners to understand the challenges in implementing sustainable supply chain management practices. Data were collected through semistructured face-to-face interview of 21 practitioners with a minimum 3 years of professional experience using the purposive sampling strategies of key knowledgeables and snowball to achieve saturation. Interviews were transcribed and analyzed guided by the Husserlian transcendental phenomenological approach for essences. The major finding was that the cost of implementing sustainability initiatives and poor government policies and regulations were the most significant barriers. Sustainability in the supply chain is still at its infancy in Nigeria, with room for improvement. The findings could contribute to positive social change as supply chain practitioners may better engage stakeholders and implement sustainability practices that minimize the negative effects of their supply chain operations on society and the environment.

Abstract:

Traditionally, environmental impacts of man made products have been determined by performing a life cycle assessment (LCA) on the product. As the name implies, LCA is usually covers the entire life of the product in a so-called "cradle-to-grave" assessment. In determining environmental impacts over the whole product life, LCA's are reasonably adequate. However, in providing detailed impacts on a particular phase of life, LCA's are lacking. Detailed assessments are important because very few stakeholders have influence over a product during all phases of life. Stakeholders need detailed impact assessments in their particular phase of life. More detailed assessments give stakeholders more information that can be used for better environmental management (EM) and more environmentally benign operations. In many LCA's, the manufacturing phase of life has been over-generalized and over-simplified because of its relatively small environmental impact, as compared to other phases of life. Nevertheless, certain stakeholders, such as manufacturing companies, need detailed impact information for the manufacturing phase of life so that they can create a more sustainable manufacturing process. Most traditional LCA's use a case-based approach, which was deemed to be inadequate. For these LCA's, the information provided for each case is often quite detailed and specific. However, this makes the assessment less flexible, limiting the quality of the assessment to the degree that the current scenario matches the existing cases. In order to make a more user-specific assessment, a model-based approach was used. To give the model flexibility, a parametric model was created based on mathematical equations that represent various parts of the manufacturing process. To give the model structure, an activity-based costing (ABC) approach was used. Using the ABC structure, the manufacturing process was broken down into activities, each of which was characterized by mathematical models. Large models would be difficult to construct and simulate by hand, so a model was built with the aid of a computer. The modeling language SysML (Systems Modeling Language) was used to create an object-oriented model of the manufacturing process, using the ABC structure. SysML defines overall properties and behaviors of the various elements in the model, while the plug-in tool ParaMagic was used to execute the model via a Mathematica Solver. The model computes carbon dioxide emissions, energy consumption, and waste mass generation for a particular manufacturing scenario. The goal of the model was to quantify environmental impact factors in order to aid manufacturing stakeholders in EM. The overall goal of the research was to determine whether an activity-based, object-oriented model was a valid approach, and whether the computer-aided tools adequately implemented this approach. Findings show that SysML is capable of modeling large and complex systems. However, due to some limitations of Paramagic, only some of SysML's capabilities were utilized. Nevertheless, Paramagic is capable of extracting information out of a manufacturing model built in SysML, and solving parametric relations in Mathematica in a timely manner. Timely solutions of complex models are critical for stakeholders keeping a competitive edge.

Abstract:

This dissertation approaches the question of sustainability and its influence on company performance, with special focus on the manufacturing industry. In the contemporary production environment, manufacturing operations must take into account not only profit, but also environmental and social performance, in order to ensure the long-term development of the company. Companies have to decide whether they should allocate resources to environmental and social practices in order to improve their competitive advantage. Consequently, in decision-making processes concerning operations, it is important for companies to understand how to coordinate profit, people, and planet. The objective of this dissertation was to investigate the current situation regarding manufacturers’ sustainable initiatives, and to explore the relationship between these sustainable practices and companies’ performance, including financial performance, operational performance, innovation performance, environmental performance, and social performance. First of all, a structured literature review was conducted to identify sustainable factors considered to be important in the decision making of manufacturing operations. The findings were synthesized into a conceptual model, which was then adopted as the basis for designing the survey instrument used in this dissertation. Drawing on Global Reporting Initiative (GRI) reports, empirical research was performed to explore the relationship between environmental management practices and company performance. Interestingly, the findings showed that many environmental management practices had a strong positive impact on innovation performance. Sustainability disclosures and financial performance were further analyzed using extended data from the GRI reports. The results also showed that several sustainability performance indicators, such as product responsibility, human rights, and society, displayed a significant and positive correlation with return on equity in the sample companies. In order to further explore the research area and to verify these findings, a triangulation approach was adopted and new data were collected via a survey conducted among middle and large sample companies in the Swedish manufacturing industry. The results indicated that the sustainable improvement practices had a positive impact on company performance. Some environmental and social improvement practices had a direct and positive correlation with product and process innovation. Furthermore, findings suggested that better cooperation with suppliers on environmental work could help to strengthen the organizational green capabilities of the focal companies. When considering the company’s general approach to implementing sustainable practices, some interesting findings emerged. There were limited significant differences in sustainable practices when comparing different manufacturing sectors, and different countries and regions. However, the results showed that Swedish manufacturing companies often place higher priority on implementing economic and environmental sustainability practices than on social ones. This dissertation contributes to the literature on manufacturing sustainability. The study expands the understanding of how environmental, social, or economic perspectives as a triple bottom line can influence company performance and to a certain extent the supply chain. Identifying and understanding such relationships gives companies the opportunity to integrate sustainability into their manufacturing operations strategy in order to sustain their manufacturing operations over the long term.

Abstract:

In the last two decades, energy is becoming one of the main issues in the manufacturing industry as it contributes substantially to production cost, CO2 emissions, and other destructive environmental impact. Due to rising energy costs, environmental concerns and stringent regulations, manufacturing is increasingly driven towards sustainable manufacturing which needs to address the associated environmental, social and economic aspects simultaneously. One common approach is to achieve sustainability and to implement energy-resource efficient production management systems that enable optimisation of energy consumption and resource utilisation in the production system. However, by reducing energy consumption, the product quality and production cost may be compromised. To remain competitive in the dynamic environment, the energy-efficient management system should not only concern energy consumption but also maintain product quality and production efficiency. This thesis presents a development of the Energy-smart Production Management (e-ProMan) system which provides a systematic, virtual simulation that integrates manufacturing data relating to thermal effect and correlation analysis between energy flow, work flow and data flow for the heating, ventilation and air conditioning (HVAC) system and production process. First, the e-ProMan system comprises of the multidimensional analysis between energy flow, work flow and data flow. The results showed that the product quality is significantly affected by ambient temperature in CNC precision machining. Product quality appears to be improved at lower temperatures. This research highlights the significance of ambient temperature in sustainable precision machining. Second, the simulation experiment was modelled at the production process due to it being the main source of energy consumption in manufacturing. An up-hill workload scenario was found to be the most energy and cost-efficient production processes. In other words, energy consumption, CO2 emission and total manufacturing cost could be reduced when workload capacity and operating machine increase incrementally. Moreover, the e-ProMan system was modelled and simulated using the weather forecast and real-time ambient temperature to reduce energy consumption of the HVAC system. The e-ProMan system results in less energy consumption compared to the fuzzy control system. To conclude, the e-ProMan demonstrates energy efficiency at all relevant levels in the manufacturing: machine, process and plant. For the future research, the e-ProMan system needs to be applied and validated in actual manufacturing environments.

This thesis examines the existing frameworks for energy management in the brewing industry and details the design, development and implementation of a new framework at a modern brewery. The aim of the research was to develop an energy management framework to identify opportunities in a systematic manner using Systems Engineering concepts and principles. This work led to a Sustainable Energy Management Framework, SEMF. Using the SEMF approach, one of Australia's largest breweries has achieved number 1 ranking in the world for water use for the production of beer and has also improved KPI's and sustained the energy management improvements that have been implemented during the past 15 years. The framework can be adapted to other manufacturing industries in the Australian context and is considered to be a new concept and a potentially important tool for energy management.

Abstract:

Manufacturing companies must consider the environmental and social aspects of their business in order to meet the requirements of sustainable manufacturing (SM). In this context, traditional manufacturing management techniques are being challenged because they do not address environmental concerns. Therefore, to meet the commitment to sustainability, a new manufacturing paradigm is needed to improve these techniques in order to assist practitioners and researchers in overcoming this new challenge. This study addresses Lean Six Sigma (LSS) and Life Cycle Assessment (LCA) as important live manufacturing improvement techniques that are currently handled independently, but there could be value in bringing them together. Researching the integration of LSS and LCA is expected to reveal improvement opportunities that would enhance the financial and environmental performance of SM. The main objective of this research has been therefore to design a framework to integrate LSS and LCA so as to yield an outcome better than that obtained if the two methods are applied in isolation. The thesis explores SM through an extensive literature review and then proceeds with data collection using a mixed-methods approach. Analysis of the knowledge and data acquired reveals that communication, environmental strategy and the market are important factors in integrating LSS and LCA. The data is also used to examine the current state of sustainability in a sample of companies by examining the recommendations put forward by other researchers for the transition to SM. The results show that most companies struggle in SM because these recommendations are not adopted. The findings of the study lead to the development of a framework that can be used to support decision making in sustainable manufacturing and to guide environmental improvement projects. The framework illustrates how conducting a LCA study provides the information to formulate an environmental strategy, and how to undertake a LSS project to make improvements. The framework highlights the importance of upgrading standard LSS tools to include environmental measures. Finally, thought experiments are conducted to demonstrate the usefulness of the framework.

Abstract:

In the current global climate of declining fossil fuel reserves and due to the impact of industry on the natural environment, industrial sustainability is becoming ever more important. However, sustainability is quite a vague concept for many, and there are a range of interpretations of the word. If the resource efficiency of a factory is taken as a measure of its sustainability, then the concept becomes better defined and quantifiable. In order to analyse the resource efficiency of a factory and suggest improvements, all flows through the manufacturing system need to be modelled. However the factory is a complex environment, there is a wide variation in the quality levels of energy as well as the composition of material flows in the system. The research presented in this thesis shows how the thermodynamics-based concept of ‘exergy’ can be used to quantify the resource efficiency of a factory. The factory is considered an ‘integrated system’, meaning it is composed of the building and the production processes, both interacting with each other. This is supported by three case studies in different industries that demonstrate the practical application of the approach. A review of literature identified that it was appropriate to develop a novel approach that combined exergy analysis with the integrated view of the factory. Such an approach would allow a ‘holistic’ assessment of resource efficiency for different technology options possibly employable. The development of the approach and its illustration through practical case studies is the main contribution of the work presented. Three case studies, when viewed together, illustrate all aspects of the novel exergy based resource accounting approach. The first case study is that of an engine production line, in which the resource efficiency of this part of the factory is analysed for different energy system options relating to heating ventilation and air conditioning. Firstly, the baseline is compared with the use of a solar photovoltaic array to generate electricity, and then a heat recovery unit is considered. Finally, both of these options were used together, and here it is found that the non-renewable exergy supply and exergy destruction are reduced by 51.6% and 49.2% respectively. The second case study is that of a jaggery (a sugar substitute) production line. The exergy efficiency of the process is calculated based on varying the operating temperature of the jaggery furnace. The case study describes the modelling of al flows through the jaggery process in terms of exergy. Since this is the first example of an exergy analysis of a jaggery process, it can be considered a minor contribution of the work. An imaginary secondary process that could utilize the waste heat from the jaggery process is considered in order to illustrate the application of the approach to industrial symbiosis. The non-renewable exergy supply and exergy destruction are determined for the baseline and the alternative option. The goal of this case study is not to present a thermally optimized design; rather it illustrates how the exergy concept can be used to assess the impact of changes to individual process operations on the overall efficiency in industrial symbiosis. When considering natural resource consumption in manufacturing, accounting for clean water consumption is increasingly important. Therefore, a holistic methodology for resource accounting in factories must be able to account for water efficiency as well. The third case study is that of a food production facility where the water supply and effluent are modelled in terms of exergy. A review of relevant literature shows that previously, the exergy content of only natural water bodies and urban wastewater had been quantified. To the author’s knowledge, this is the first example of applying this methodology of modelling water flows in a manufacturing context. The results show that due to a high amount of organic content in food process effluent, there is significant recoverable exergy in it. Therefore, a hypothetical water treatment process was assumed to estimate the possible savings in exergy consumption. The results show that at least a net 4.1% savings in terms of exergy could be possible if anaerobic digestion water treatment was employed. This result can be significant for the UK since the food sector forms a significant portion of the industry in the country. Towards the end of the thesis, a qualitative study is also presented that aims to evaluate the practical utility of the approach for the industry. A mixed method approach was used to acquire data from experts in the field and analyse their responses. The exergy based resource accounting method developed in this thesis was first presented to them before acquiring the responses. A unanimous view emerged that the developed exergy based factory resource accounting methodology has good potential to benefit industrial sustainability. However, they also agreed that exergy was too complex a concept to be currently widely applied in practice. To this effect, measures that could help overcome this barrier to its practical application were presented which form part of future work.

Abstract:

A paradigm shift is taking place in the manufacturing industry, where companies strive for adopting digital tools to be able to compete against their competitors. The endeavor of becoming digitized is taking place simultaneously as the global awareness of sustainability increases. For the reasons that current literature is experiencing a knowledge gap that links data-driven processes, sustainability, and supply chain operations, there is a need for further exploration within this area. Therefore, the aim of this report is to investigate the business opportunities and challenges of data-driven decision-making, and how it relates to more sustainable supply chain operations within the manufacturing industry. To investigate the area within data-driven decision-making and its impact on manufacturing supply chain operations, a literature review was initially conducted and was followed by interview sessions with case companies and experts. In total, 14 interviews were conducted within the area of sustainability, supply chain operations, and data-driven decision-making. The interviews were conducted to follow the designed framework and thus provide knowledge for the challenges, advantages, applications, and value capture in relation to data-driven decision-making and supply chain operations. Comparing the empirical data with previous literature it was noted that data-driven decision-making entails both multiple challenges and advantages when it comes to improving manufacturers' sustainable performance. The main challenges include establishing efficient information sharing, standardized systems, and obtaining data that shows both reliability and validity. Consequently, by solving these challenges the sustainable benefits can be fulfilled, including a mitigated bullwhip-effect, improved planning, and reduced CO2 emissions. These benefits are driven by the transparency, automatization, and optimization that is incorporated with data-driven decision-making. In conclusion, realizing data-driven decision-making within the manufacturing industry entails several challenges, but if companies overcome the challenges the potential benefits will be unlimited.
Ett paradigmskifte pågår för närvarande i tillverkningsindustrin, där företag strävar efter att använda digitala verktyg för att kunna konkurrera mot sina konkurrenter. Strävan efter att bli digitaliserad sker samtidigt som den globala medvetenheten om hållbarhet ökar. Av anledningarna till att den aktuella litteraturen upplever ett tomrum av kunskap som länkar datadrivna processer, hållbarhet och leveranskedjedrift, så finns det ett behov av ytterligare forskning inom detta område. Målet med denna rapport är därför att undersöka affärsmöjligheterna och utmaningarna med datadrivet beslutsfattande, och hur det relaterar till mer hållbara försörjningskedjor inom tillverkningsindustrin. För att undersöka området inom datadrivet beslutsfattande och dess inverkan på leveranskedjedriften och tillverkningsindustrin så genomfördes först en litteraturundersökning som följdes av intervjussessioner med utvalda företag och experter inom området. Sammanlagt intervjuades nio företag och sex experter som valdes ut efter deras kompetenser inom hållbarhet, leveranskedjedrift och datadrivet beslutsfattande. Intervjuerna genomfördes med hjälp av en intervjuguide och därmed ge kunskap om kopplingarna mellan data, aktuella affärsverksamheter och förbättrad ekonomisk, social och miljöprestanda. Detta inkluderar att utforska utmaningar, fördelar, applikationer och värdefångst i kontext till datadrivet beslutsfattande och leveranskedjedrift. Vid analysen av EMPIRISK data och jämförelse med aktuell litteratur noterades det att datadrivet beslutsfattande medför flera olika utmaningar och fördelar när det gäller att förbättra tillverkningsföretagens hållbara prestanda. De viktigaste utmaningarna är att etablera effektiv informationsdelning, standardiserade system och att erhålla data som visar både tillförlitlighet och giltighet. Genom att hantera dessa utmaningar kan de hållbara fördelarna uppnås, vilket inkluderar en minskad bullwhip-effekt, koldioxidutsläpp och förbättrad planering. Dessa fördelar drivs vidare av transparens, automatisering och optimering som ett datadrivet beslutsfattande medför. Sammanfattningsvis innebär förverkligandet av att använda datadrivet beslutsfattande inom tillverkningsindustrin flera utmaningar, men om företag övervinner utmaningarna kommer de potentiella fördelarna att vara obegränsade.

Abstract:

Sustainable Value Stream Mapping (Sus-VSM) builds upon traditional VSM to capture additional sustainability aspects of the product flow, such as environmental and societal aspects. This work presents research to expand the utility of Sus-VSM to supply chain networks, develop a general approach towards improving supply chain sustainability, and examine the benefits of implementing simulation and a design of experiments (DOE) style analysis. Metrics are identified to assess economic, environmental, and societal sustainability for supply chain networks and visual symbols are developed for the Supply Chain Sus-VSM (SC Sus-VSM) to allow users to easily identify locations where sustainability can be improved. A discrete event simulation (DES) model is developed to simulate the supply chain, allowing easier creation of future state maps, which are used to identify locations for sustainability improvement. A scoring methodology and DOE-style analysis are developed to collect more information from the supply chain. Results from the case study show that the SC Sus-VSM meets the goals desired, and that the DES model aids the goals of the map. It is also indicated that interventions in the supply chain should first focus on economic improvements, followed by societal and then environmental improvements to achieve the greatest supply chain sustainability.

Abstract:

Since the onset of the industrial revolution, manufacturing companies have contributed significantly to the degradation of the natural environment. Over the last two decades, businesses have been increasingly required to consider the impact of their activities on the environment. This trend comes as a response to the mounting market and legislative pressure experienced by manufacturing companies in the developed world. Small and Medium sized Enterprises (SMEs) play an important role in the economies of most developed countries. The combined environmental impact of SMEs is thought to be very significant. This has been estimated to be as high as 70% of total global pollution. However, manufacturing SMEs face significant barriers in adapting to the growing requirements for improved environmental performance. In comparison to large companies SMEs have limited resources for voluntary improvement initiatives and lack specialist sustainability expertise. Existing environmental improvement methods are not suited to the characteristics and requirements of SMEs. Given the particular challenges faced by manufacturing SMEs, these companies have generally taken a defensive approach to environmental improvement. In order to make significant progress towards global sustainable development, SMEs need to improve their capabilities and achieve 'managed' and 'integrated' business sustainability maturity levels. The aim of this PhD was to develop framework elements for manufacturing SMEs to progressively implement and integrate environmental sustainability strategy into their business. The research design involved three phases and used a triangulated action research approach. The Baseline Research Phase had the aim of developing a framework to progress manufacturing SMEs to a proactive maturity level. A systems model of the relationship between SME characteristics and the barriers to the uptake of voluntary environmental improvement initiatives was developed. A conceptual Baseline framework was conceived to overcome the uptake barriers. The Baseline framework used a combination of existing strategic business tools (such as SWOT and stakeholder analysis) and approaches developed in this research (e.g. environmental improvement project prioritisation) to address the specific barriers of SMEs. The framework was tested in an action research study of a New Zealand furniture manufacturing SME. As a result of the framework implementation, the Towards Environmentally Sustainable Manufacturing: A Strategic Framework for Small and Medium sized Enterprises owner/managers of the company exhibited increased support for environmental improvement. The Strategising Research Phase had the aim of developing a strategic framework to progress manufacturing SMEs from a 'proactive' to a 'managed' environmental sustainability maturity level. Implementation of an Environmental Management System (EMS) is known to facilitate a managed approach to continual improvement of environmental performance. However, a literature review and survey of ISO 14001 certified manufacturing companies identified the particular barriers that SMEs experience in the implementation of an EMS in comparison with large companies. An EMS strategy framework was developed and subsequently tested in an action research study to address the barriers. A generic ecoWheel for the wood panel furniture industry was conceived based on the implementation of the framework in a second case study. The EMS strategy framework successfully mitigated the key EMS implementation barriers. The Integrating Research Phase involved the development and testing of an information technology infrastructure, ecoPortal, to facilitate the integration of the EMS strategy into the culture and day-to-day activities of manufacturing SMEs. Requirements for the ecoPortal system were based on a review of the literature and the implementation of an eco-design programme in an action research study. The ecoPortal was tested in a case study of a product stewardship project at a textile manufacturing SME. The ecoPortal provides a communication, knowledge management and collaboration platform for manufacturing SMEs to implement their EMS strategy. Future research should focus on the wider implementation of the framework elements and ecoPortal infrastructure in manufacturing SMEs. In addition to this, the framework could be expanded to integrate health & safety and quality management systems.

Abstract:

A growing uncertainty in the global economy is forcing many manufacturers to reassess their corporate outlook towards the environment. Today there is a growing attention to sustainability in industry accompanied by a paradigm shift towards realizing a sustainable society. It is now very common to hear about Green Production and Green Systems, but few literature exist that deal with the relatively newer subject of Green Maintenance. The term green production is often used to describe production with a sustainable perspective. Also, lean production has been proposed as a means of achieving sustainability. Lean and Green production systems require efficient production and low use of resources such as energy, materials, etc. One major facilitator of this is effective maintenance. Sometimes regarded as the necessary evil, maintenance still has a negative image in the industry. But as the paradigm on manufacturing shift towards realizing a sustainable society, we should also begin to realize the changing role of maintenance. Still, the impact of maintenance on sustainability and Green production is not very well described in research. This Master Thesis within the School of Innovation Design and Engineering at Mälardalen University presents a literature review on green maintenance by trying to identify and assess the key factors of maintenance effects on green production, life cycle assessment and sustainability of maintenance activities. In addition, a brief introduction to the greening of remanufacturing activity, part of a green process by itself, is provided. The research is based upon extensive literature study, questionnaire survey and interviews with relevant industry as well as academic personnel. A discussion of the results of the interview followed by a conclusion on the key factors of maintenance on sustainability is provided. Future research areas have also been suggested. Keywords: Green maintenance, Production maintenance, Sustainable maintenance, Total Productive Maintenance

Abstract:

This thesis is concerned with developing a framework for the sustainable manufacturing of technologies in Sub-Saharan Africa, focusing on Ghana, for local industry. The interest here is on manufacturing and production technologies. Drawing on the work of Clemens and Dalrymple (2005), a three step approach emerged as an overarching methodology leading to the construction of the Ghana manufacturing of technology model (GMTM). The work of Sagasti (1992) provided the framework for its construction. The aim here is to investigate to understand what factors account for the state of technology drawback in Ghana, so as to be able to explain them. A multidisciplinary approach was therefore required and employed. Owing to the human and cultural understanding required here, a mixed-research approach involving ethnography, grounded theory and case-study was found to be most suitable. This involved data from two rural communities, expanding to the urban areas where government officials, policy makers and heads of institutions were interviewed. The corpus of data was analysed using grounded theory and a case study of the shea butter industry provided further insights. The findings, among other things, suggest that Ghana has no focused framework for technology manufacturing for local industry. The study noted that the cultural and ethnic division in traditional Ghana, inhibits knowledge and cultural exchange, hence, affecting the deployment and advancement of traditional technologies in the "closed" societies. This division is reflected in the formal Ghanaian sector, which side-lines the traditional sector from development and industrialisation decision making. Government Officials and policy makers were found to be vague on technology development for local industry, but were focused on developing high-techs, like nano-technologies and science parks. The study sees this as misplaced priority. The technology drive will require a business model, which falls outside the scope here, hence left for future work. A new concept of development engineering emerges from the study.

Abstract:

Introduction: Producing on a global scale is attractive for multinational corporations (MNCs) due to production cost savings and the proximity as well as simplified access to new high growth markets. In order to be successful in foreign markets it is vital for MNCs to understand the local market conditions. In particular stakeholders, also referred to institutions, and their diverse demands are likely to vary among differently industrialized country markets. Additionally, sustainability has emerged as an inevitable topic for businesses and countries alike. Purpose: Therefore, the purpose of this thesis is to describe and analyze different institutions and their demands in differently industrialized countries. Moreover, the aim is to describe and analyze capabilities that manufacturing companies can use to respond to these institutional demands in order to achieve a more sustainable production. Methodology: The research method employed is a single embedded case study consisting of one Scandinavian multinational machinery and construction equipment manufacturer with three production units located in Sweden, Bulgaria and China. Semi-structured interviews with managers, a supplementary questionnaire and a literature review on institutional and capability theory serve as sources for primary and secondary data collection. Findings: There are differences between institutional demands among differently industrialized countries. The research found that manufacturing units in developed and ECMs can respond to these institutional demands through different capabilities. Next to institutional demands there are certain institutional influences that are beyond the control of the MNC and can only be absorbed. By having a diverse set of economic-, natural- and social capabilities which are difficult to copy and that are corresponding to various institutional efficiency and legitimacy demands as well as influences manufacturing companies can create a more sustainable business. Research and practical implications: Future qualitative research could seek to explore whether the results of this study are congruent for companies operating in other industries and other countries. Next, future research could seek to explore whether there are more evident natural and social based capabilities existing in the field.Within praxis, it is critical for managers to be aware that each country has its distinctive context and that it is necessary to locally adapt in order to satisfy the prevailing market conditions. Besides it is essential not only to satisfy the customer demands but also to identify and respond to other institutional demands to create a more sustainable production.

Abstract:

In the rapidly changing global scenario, it became increasingly clear that new thinking was required to make businesses competitive given the challenges of liberalised trade regimes, free flow of capital and knowledge. The prodigious marriage of computers, communications and technology provided lot more options to the consumers, competitors, employees, suppliers and providers of money alike. Customers and Consumers have become more demanding, not only in terms of product quality or costs but also innovations and detect free services. The Author, anticipating the change, advised the Chairman of the Aditya Birla Group, (with sales and assets in excess of 6 billion US dollars and having manufacturing sites in India, Thailand, Philippines, Thailand, Malaysia, Indonesia, Egypt and Canada), to focus on lifting the standards of Manufacturing in all his Units. The Author joined the Group in late 1996 as The President of World Class Manufacturing, a Corporate Function, as a direct reporter to the Chairman Some companies in the Group, which are making good profits, perceived themselves as World Class since they had obtained ISO Certification, and a few other Awards. Yet others were pursuing customers with their own definition of quality, costs and delivery. And some were pursuing improvement programs under external consultant's guidance. The business went on as usual, except more explanation of how competition was increasing, and generic statements like "ve are doing all we can to deal with the situation which should improve soon" It was in the above context that Author thought of trying holistic approach for Good Governance at all levels, at all locations, involving all employees and all activities with focus on Manufacturing since best of marketing efforts would be in vain if not backed up by a World Class product with right cost and delivery. Anticipating the future needs, Author wanted everyone to focus on Innovations and Intellectual Capital and highest levels of Productivity from the six Ms [we call it. Men or Women (People), Material, Machines, Methods, Measurement and Markets]. After studying current literature and case studies on the subject and interacting with his former employers in Europe, America, Africa and Asia, and his potential customers (the 67 Plants in 1997) Author devised a Model that was futuristic, holistic, simple to be understood as the 'Art of Managing the Workplace', small or big. This was supported by a detailed Road Map and Methodology for Implementation of the Revolution for Excellence in the Group. A set of unique actions that would change the Mindset and Inspire the troops were developed and applied. Each of the 67 Plants have developed and deployed its own actions for percolating the philosophy, concept, tools and technique for the Deployment, Assessment and Review for becoming a world class manufacturer (WCM) The results are most satisfying as, the Model, its Road Map and Methodology with actions for Sustaining the Momentum has led to significant improvements in Products, Processes, Mindset and Culture of the People; they have attained higher knowledge level in their work, become extremely customer focused and have sent positive signals to all the stakeholders about their ability to protect the future, enhancing the competitiveness of their business, and therefore the Nation, and thereby protect the future of the next generation of employees, investors as well as other stakeholders. The tangible savings (over a period of approximately 5 years) in both Indian rupees and UK Pounds Sterling are summarized here under. On an average there are savings of about 9.5 millions UK £ per year. The turnover of the group is about 5500 millions UK (E). The savings thus comes equivalent to about 0.2 % of the Group's turnover which is a substantial amount creating a big impact on bottom line.

Abstract:

The purpose of this qualitative collective case study was to examine the perceptions and lived experiences of senior leaders of three different small-to medium sized manufacturing companies, located in the state of Colorado, as related to success strategies and barriers to lean manufacturing implementation. Findings resulted in nine emergent themes: (a) lean manufacturing implementation should be implemented in a way specific to the context of the individual organization; (b) time, resources, and changes in customer demand present challenges in sustaining lean manufacturing implementation; (c) resistance to change is a barrier to lean manufacturing implementation; (d) small-tomedium sized companies use outside consultants and trainers for training staff on lean manufacturing implementation; (e) front line workers need to be trained to apply lean tools and concepts for successful lean manufacturing implementation; (f) front line workers have to own and believe in lean manufacturing for it to be successful; (g) senior leaders have varying definitions of what their role is in leading lean manufacturing implementation; (h) senior leaders have differing perspectives regarding the degree of leadership knowledge required for successful lean manufacturing implementation; and (i) senior leaders struggle to expand lean manufacturing implementation into support departments. Recommendations included (a) viewing lean as a philosophy for managing the business, (b) training and education for senior leaders, (c) defining senior leader roles in implementing lean manufacturing, and (d) strategies when using outside consultants in a company’s lean efforts.

Worldwide estimates indicate nearly 150 million people are homeless, and 1.6 billion lack adequate shelter. One of the biggest barriers of home ownership is cost, which is often driven heavily by the cost of materials required. Plastic waste is also at an all-time high, with over 5 billion tons of plastic on the earth's surface and in its oceans. This waste will take hundreds of years to degrade if not longer and incentives and use for recycled plastic is needed now more than ever. Making lightweight homes using 3D printed recycled polymer materials is proposed as a solution to this problem. Assuming a network of manufacturing sites, a significant number of homes could be produced, raising the issue of material selection and availability. After creating an extensive comparison of potential materials, stressing properties, availability and cost, the best candidate appears to be polyethylene terephthalate (PET). Recycled PET (rPET), is available in volumes comparable to the projected demand for low cost housing. rPET material properties optimize the feasibility, processing, and engineering use qualities of the building material, but further testing is necessary to explore the effect of feedstock processing and additives on the performance of the material. This thesis examines the choice of (rPET) as the best potential material for large scale 3D printing of low-cost homes and presents an experimental setup for confirming this hypothesis.

Abstract:

In the late 1990s New Zealand fashion gained some international recognition for its dark edginess and intellectual connection due to its colonial past (Molloy, 2004). In the years since, this momentum seems to have dissipated as local fashion companies have followed a global trend towards inexpensive off shore manufacturing. The transfer of the making of garments to overseas workers appears to have resulted in a local fashion scene where many garments look the same in style, colour, cut and fit. The excitement of the past, where the majority of fashion designers established their own individuality through the cut and shape of the garments that they produced, may have been inadvertently lost. Consequently a sustainable New Zealand fashion and manufacturing industry, with design integrity, seems further out of reach. The first question posed by this research project is, ‘can the design and manufacture of a fashion garment, bearing in mind certain economic and practical restrictions at its inception, result in the development of a distinctive ‘look’ or ‘handwriting’?’ Second, through development of a collection of prototypes, can potential garments be created to be sustainably manufactured in New Zealand?

Abstract:

The aim of this study is to research environmental factors and their impact among manufacturing companies in Umeå. In order to capture the essence of environmental impacts , two research questions were asked; which environmental factors are considered, and in what context are they evaluated among manufacturing companies in Umeå, and how are stakeholders an implication on corporate environmental efforts for manufacturing companies in Umeå?

First and foremost relevant theories were discovered, using several databases. Second, they were incorporated into a conceptual framework, where their relationship and characteristics were displayed. The theories were then transformed into themes, which became the foundation of the interview guide.

The study was conducted by interviewing six manufacturing companies with more than 10 employees in Umeå. The interviews were semi-structured, and a mixture of telephone interviews and in-person interviews. An analysis of the empirical material was undertaken, by analyzing the data using the theories found during the information search.

Almost all participating companies consider environmental factors in one way or another, according to the findings of this study. Further, the customers were concluded to be the most important stakeholder in leading to environmental reform among the companies. However, other stakeholders were also recognized by the respondents, and had an impact in for the stakeholders’ specific circumstances.

Abstract:

Sustainable manufacturing is becoming increasingly important due to scarcity of natural resources, stricter regulations and increasing customer demand for sustainable products. Sustainable manufacturing involves the use of sustainable processes and systems to produce more sustainable products. In order to meet these demands for sustainable products, manufacturing companies have to adopt numerous strategies to achieve sustainable manufacturing. The approach for evaluating sustainable products and processes have been investigated in previous work where product/process sustainability indices were proposed. However, no comprehensive methods are available for sustainable manufacturing performance evaluation at the system level. This work aims to develop two alternate methods for evaluating sustainable manufacturing performance at enterprise, plant and production line levels. First, requirements for a sustainability metrics framework are identified through studying and reviewing existing literature where the three pillars of sustainability, total life-cycle stages, and 6R concepts are concurrently addressed. Then index-and value-based methods are proposed to evaluate sustainable manufacturing performance by conducting assessment on economic, environmental and societal aspects. Finally, the application of these two methods is illustrated for a representative enterprise producing consumer electronics at the enterprise level; a case study for a satellite television dish production is used to demonstrate the application of these methods at the production line level. Results obtained from these two methods are compared and analyzed at the enterprise level. The proposed methods can provide information to a company to identify improvement strategies and for decision making for sustainable development.

Abstract:

As a result of digitalization, previously analog systems in the manufacturing industry have become digitalized, including the decision-making processes. Companies are, therefore,becoming more dependent on data for strategic decisions. However, because of the rapid development of digitalization, companies are left blindfolded in the path towards smarter manufacturing which often leads to unsuccessful technological implementations. Therefore, the thesis will explore this problem by asking: What are the required initiatives for successfully implementing digital data-driven decision-making to improve efficiency and sustainability by Swedish manufacturing companies? To answer the research questions, an exploratory multiple case study approach was conducted, where interviews with informants from the industry as well as researchers within the context of smarter manufacturing were made. The findings were then used to derive propositions which worked as the foundation of a conceptual model which functionality would be to illuminate the results in the form of a strategy map. Findings suggest that it is not always necessary for companies to implement technologies linked to large investments to enable digital data-driven decision-making. However, for those that do, there needs to be a clear organizational plan and agenda before executing theprojects since they otherwise often lead to insufficient results. That means, the technological aspects are often not the culprit in failed digital data-driven decision-makingprojects. Additional findings suggest that there are synergies connected to digital data-driven decision-making such as data-sharing possibilities that have the potential of becoming a major aspect within the context of sustainability and efficiency.
Som ett resultat av ökad digitalisering har analoga system i tillverkningsindustrin blivit digitaliserade, vilket inkluderar beslutsfattandet. Företag har därför börjat förlita sig alltmer på data för sina strategiska beslut. Men på grund av den snabba utveckling av digitalisering har tillverkningsföretagen lämnats utan klara riktlinjer för hur de bör gå tillväga för att implementera digitalt datadrivet beslutsfattande på ett effektivt men hållbart sätt. Avhandlingen kommer därför att undersöka detta problem genom att fråga: Vilka är de initiativ som krävs för att framgångsrikt implementera digital datadrivet beslutsfattande med målet att förbättra effektiviteten och hållbarheten hos svenska tillverkningsföretag? För att svara på forskningsfrågorna användes en undersökande metod med flerafallstudier, där intervjuer gjordes med informanter från industrin såväl som forskare inom ramen för smartare tillverkning. Resultaten användes sedan för att härleda förslag som därefter användes till konstruktionen av en konceptuell model vars huvuduppgift var att illustrera resultaten i form av en strategikarta. Slutsatserna pekar på att det inte alltid är nödvändigt för företag att implementera teknik kopplad till stora investeringar för att möjliggöra digitalt datadrivet beslutsfattande. Men för de som valt att implementera sådana system behövs en tydlig organisationsplan innan projekten genomförs eftersom de annars ofta leder till ofördelaktiga resultat. Detta tyder på att de tekniska aspekterna oftast inte är vad som orsakar misslyckade datadrivna beslutsprojekt. Dessutom tyder resultaten på att det finns synergier kopplade till digitalt datadrivet beslutsfattande, till exempel möjligheter att dela data som har potential att bli en viktig aspekt inom hållbarhet och effektivitet.

High fixed costs and the emergence of globalization have forced traditional domestic automotive mass producers to the brink of bankruptcy. This thesis focuses on the global growth strategy of a Tier 1 automotive supplier and examines causal relationships between that strategy and the system stakeholders who execute and support it. The literature review examines current research to illustrate the benefit of approaching globalization with a process-driven, systems-based mindset. Current literature offers insight into improved financial measures that traditional mass producing firms can employ to streamline decision making and shift the mindset of leaders to engage employees, suppliers, and customers around a long-term systems based operating strategy. The thesis is based upon three core experiences the author had at American Axle to illustrate the importance of systems-based operations innovation. The literature review in conjunction with the internship experience is used to illustrate opportunities for American Axle to improve its operating strategy. The paper highlights traditional approaches currently used inside the company and offers solutions to change employee behavior throughout American Axle's global manufacturing system. The thesis examines behaviors, metrics, and results often seen in an absorption cost environment where there are weak operational controls and non-standard corporate scorecards. Using current research and professional industry experience, I will argue robust operational controls and metrics, aligned with an overarching systems approach that considers the long term implications of today's decisions, are essential components to the viable, long term success of any global enterprise.

Abstract:

Titanium and its alloy (Ti-6Al-4V) are widely used in aerospace industries because of their light weight, high specific strength, and corrosion resistance. This study conducted a comparative experimental analysis of the machinability of Ti-6Al-4V for conventional flood coolant machining and sustainable dry machining. The effect of cutting speed, feed rate, and depth of cut on machining performance has been evaluated for both conditions. The machining time and surface roughness were found to be lower in dry machining compared to flood coolant machining. The tool wear was found to be unpredictable, and no significant difference was observed for dry and coolant machining. In a comparison of all the parameters, sustainable dry machining was found to provide better performance in machining Ti-6Al-4V. This study also investigated the machinability of Ti-6Al-4V using coated and uncoated tungsten carbide tools under dry conditions. Tool wear is a serious problem in the machining of titanium alloys in dry conditions. Heat dissipation from the toolworkpiece interface a difficult challenge in dry machining, resulting in the alloying of the workpiece to the tool surface. Dry machining with the coated tool was comparatively faster, and resulted in less tool wear than uncoated tools. Using the Titanium aluminum nitride TiAlN coated carbide tool during dry machining provided a smoother surface finish with lower average surface roughness. The conclusion, therefore, is that the tool coating was found to be effective for the dry machining of titanium alloys.
