Due to the global expansion of Company A's supply chain network, it is becoming more vulnerable to many disruptions. These disruptions often incur additional costs; and require time to respond to and recover from these disruptions. The base paper supply chain was identified as the most vulnerable area of the Company A Jurong and South & Southeast Asia Cluster supply chain; and a multi-stage supply chain was proposed to improve the supply chain's resilience. A statistical model was constructed to select the optimal location of the central warehouse for the proposed multi-stage supply chain. After evaluating the resilience to disruptions and the cost effectiveness of supply chains, the multi-stage supply chain with central warehouse in Tanjung Pelepas, Malaysia was found to be overall most resilient and cost effective among all the supply chains. It also incurs a lower additional cost in the event of a disruption such as changes in exchange rates and demand forecast accuracy, fuel price fluctuation, labor cost increase and shipping disruptions. As a result, establishing this multistage supply chain is recommended.

Abstract:

Today’s dynamic and increasingly competitive market had expanded complexities for global businesses pressuring companies to start leveraging on Big Data solutions in order to sustain the global competitions by becoming more data-driven in managing their supply chains.The main purpose of this study is twofold, 1) to explore the implications of applying analytics designing supply chain networks, 2) to investigate the link between operational and strategic management levels when making strategic decisions using Analytics.Qualitative methods have been applied for this study to gain a greater understanding of the Supply Chain Analytics phenomenon. An inductive approach in form of interviews, was performed in order to gain new empirical data. Fifteen semi-structured interviews were conducted with professional individuals who hold managerial roles such as project managers, consultants, and end-users within the fields of Supply Chain Management and Big Data Analytics. The received empirical information was later analyzed using the thematic analysis method.The main findings in this thesis relatively contradicts with previous studies and existing literature in terms of connotations, definitions and applications of the three main types of Analytics. Furthermore, the findings present new approaches and perspectives that advanced analytics apply on both strategic and operational management levels that are shaping supply chain network designs.

Abstract:

This thesis studies the influence of horizontal competition on supply chain performance. Unlike most of the existing literature which focuses on horizontal competition between echelon levels, we look at both the supply chain and the individual company??s performance with the presence of supply chain to supply chain competition. Specifically, this thesis is composed of three individual research papers. The first paper deals with chain-to-chain horizontal competition and considers price competition among an arbitrary number of supply chains by comparing two cases. In the first case each supply chain is vertically integrated, while in the second, decentralised, case the manufacturers and retailers act independently. We explore the effect of varying the level of price competition on the profitts of the industry participants and demonstrate the important role played by the spread of underlying market shares. The coefficient of variation of these market shares determines whether decentralised supply chains can outperform integrated supply chains with an appropriate level of competition. The second and third papers focus on in-chain horizontal competition with capacity constraints. In the second paper, we look at a supply chain with one manufacturer and two downstream retailers. Based on total capacity available, the manufacturer needs to find ways to best use the capacity by determining whether or not to release the capacity information to retailers. The third paper looks at competition in a more complicated supply chain structure. A retailer buys three brands of products from two manufacturers. One manufacturer produces both branded and private label products, and the other one manufactures a branded product only. With our model, we are able to determine the profits of each supply chain agent. At the end of the paper, we use data from the Australian milk industry and discuss a problem in which a manufacturer needs to decide how to allocate capacity between the national brand and the private label when there is a capacity shortage.

The strong bargaining power of major retailers and the higher requirements for speed, service excellence and customization have significantly contributed to transform the Supply Chain Management. These increasing challenges call for an integrated and dynamic Supply Chain Management and for a better integration and alignment with key customers, in order to reduce the firm's time-to-market and build competitive advantage. The thesis aims at providing the partner company, a major player in the consumer goods industry, with a more robust and efficient vendor managed inventory practice, so that the partner can determine the optimum inventory level to satisfy turnover, service level and lead time requirements, whereas minimizing lost sales and total costs in the system. The team developed a Supply Chain Dynamics framework to help the partner to establish new service level strategies, strongly oriented to the strategic importance of its products and customers, and to map the key system-wide drivers that impact the overall number of inventory turns, service level and total costs. Additionally, in order to run simulations and estimate the outcomes of the proposed recommendations, the team developed a "Multi-Echelon" simulator and used a commercial "Supply Chain Dynamics" simulator.

The Global Business Climate has been rapidly changing and has become more competitive. Enterprise now not only needs to operate at a lower cost to compete, it must also develop its own core competencies to distinguish itself from competitors and stand out in the market. The focus has now moved towards improving operational efficiency to stay competitive. Supply Chain is one of the important areas which almost every company is currently working to improve their operation efficiency. Improving operational efficiency in supply chain has three aspects including improving supply chain strategies, following better supply chain management practices, and aligning supply chain strategy with overall business strategy. Our thesis research objective is to understand what policies, capabilities, and strategies of an enterprises leads to best supply chain management. The research is cross industry, across all supply chain management domain and will shed light on what makes companies "best performer" by identifying and exploring the distinctive capabilities required in five key supply chain domains that contribute to high performance in the relevant operational metrics. The domains studied in our research are supply chain planning, fulfillment, service management, product lifecycle management, and, manufacturing. Another objective of our thesis is to relate domain performance of the firm with the firm's value proposition. The three value propositions considered in the thesis are product leadership/innovation, cost competitiveness, and customer service.

Abstract:

Construction is a project-based industry and construction supply chains generally work with a unique product in every project. Commonly, project organizations are reconfigured for each project. This means that construction supply chains are characterised by various practices and disjointed relationships, with the result that construction supply chain actors generally have transient relationships rather than long term risk sharing partnerships. A consequence of this is the lack of trust between construction clients, designers, main contractors and suppliers. Because the construction supply chain works as a disparate collection of separate organisations rather than as a unified team, the supply chain suffers from lack of integration. Knowledge flow in construction supply chains are hindered due to the reasons such as inadequate adaptation to collaborative procurement type projects, inadequate collaboration between the downstream and upstream supply chain, lack of interoperability of the design tools, lack of well structured SCM process and lack of well developed knowledge management applications. These characteristics of the construction supply chains are the main reasons for its low efficiency and productivity in project delivery. There is a need for the development of appropriate systems to ensure the effective diffusion of knowledge such that each actor of the supply chain adds value to the project delivery process. This is expected to result in the creation of knowledge chains in construction. It is believed that construction supply chain management (SCM), when integrated with knowledge management (KM), can successfully address the major problems of the industry The main aim of this research was to develop a framework to transform construction supply chains into knowledge chains . To reach this aim, the research first provided an overview of practices and issues in SCM across a range of industry sectors including construction, aerospace, and automotive industries. It discusses research and developments in the field of SCM and KM in construction industry, the key SCM issues with a knowledge flow focus, and the best practices from other industries to improve the construction supply chains. Furthermore, the results of the company specific and project specific case studies conducted in aerospace and construction industry supply chains are presented. These results include the key SC problems, key issues related to knowledge flow and the presentation of knowledge requirements of each supply chain actor. Following the data analysis process, a framework to transform the construction supply chain into a knowledge chain taking full cognisance of both the technical and social aspects of KM was presented. The main purpose of the knowledge chain framework was to enable construction bid managers/project managers to plan and manage the project knowledge flow in the supply chain and organise activities, meetings and tasks to improve SCM and KM throughout the supply chain in an integrated procurement type (PFI) project life cycle. The knowledge chain framework was intended to depict the knowledge flow in the construction supply chain specifically, and to offer guidance for specific business processes to transform the supply chains into knowledge chains. Finally, this research focused on the evaluation of the framework through industry practitioners and researchers. An evaluation of the Framework was conducted via workshop followed by a questionnaire comprising industry experts. The findings indicated that adoption of the Framework in construction project lifecycle could contribute towards more efficient and effective management of knowledge flow, standardisation and integration of SCM and KM processes, better coordination and integration of the SC, improved consistency and visibility of the processes, and successful delivery of strategic projects. The overall research process contributed the construction research in many perspectives such as introduction of knowledge chain concept for construction supply chains; comparative analysis of the SCM practices in different industry sectors, identification of best practices for construction supply chains, better demonstration of the maturity level and critical factors of the SCM within the construction industry, demonstration of the KC framework which integrates the supply chain process and knowledge sharing within a single framework which covers all the recent trends in the construction industry like collaborative procurement route projects, creation of better integrated SCs, applications like off site construction and BIM where all supply chain management and knowledge management should take place.

Abstract:

Supply chain integration (SCI) is a phenomenon that has received growing attention from academia and industry practitioners alike. Studies suggest that firms with highly integrated supply chains can positively influence firm performance from both an operational and financial standpoint. The literature emphasizes three distinct dimensions of SCI; internal integration, supplier integration and customer integration. However, the scarcity of highly integrated supply chains could be widespread in South Africa due to the SCI perception gaps prevalent among supply chain practitioners in South Africa. The literature reveals that there are countless inconsistencies pertaining to the interpretation and execution of supply chain management practices among supply chain practitioners, across myriads of industries. This study aimed to investigate the various perceptions of the SCI construct harboured by supply chain practitioners in fast-moving consumer goods (FMCG) manufacturing firms. A generic qualitative research strategy was used as the method of inquiry in this research. Five FMCG manufacturing firms were sampled and a total of fifteen participants were interviewed though semi-structured interviews. The main findings of the study reveal that supply chain practitioners in FMCG manufacturing firms interpret the SCI construct differently. While some supply chain practitioners interpret the SCI construct in line with what is documented in the literature, others have misaligned interpretations of the construct. These differences in interpretation span across all tiers (strategic, tactical and operational) within FMCG manufacturing firms. The findings also reveal that supply chain practitioners in South African FMCG manufacturing firms, to a significant extent, identify with all the supply chain integrative practices relating to supply chain collaboration, intra/inter firm interaction and information sharing, as documented in the literature. The study’s findings contribute to the supply chain discipline by helping researchers as well as supply chain practitioners develop a complete understanding of the SCI construct which deliberately elaborates on the associated SCI dimensions, and explicitly articulates the integrative practices associated with the phenomenon. Managerial implications emanating from this study suggest that supply chain functions should strive to create awareness around the focal firm’s end-to-end supply chain activities, and how these activities impact each other. This can be done through building a culture of frequent inter- and intra- organisational interaction, as well as implementing relevant organisational learning interventions across all tiers within the focal firm. In addition, focal firms should also adopt and leverage off new technologies to ensure more reliable and real-time data, thus enabling more effective decision-making.

Abstract:

On March 2011 a destructive 9.0-magnitude earthquake and tsunami along with nuclear explosions struck northeastern Japan; killing thousands of people, halting industry and crippling infrastructure. A large manufacturing company operating outside of Japan received the news in the middle of the night. Within a few hours of the tsunami hitting Japan, this manufacturer’s logistics team ran global materials management reports to communicate the precise status of the products originating from Japan to their entire global network of facilities. With this quick and far reaching communication the manufacturer was able to launch a successful contingency plan. Alternative suppliers, already existing as part of their global network, were evaluated and used to mitigate Japan’s disruptive impact. The resiliency of this manufacturer’s trusted network of supply chain trading partners allowed for minimum disruptions, saving countless money and maintaining continuity for its end-to-end supply chain. This manufacturer was part of a cloud-based supply chain that provided the catalyst to quickly shift its resources to allay the impact of no longer being able to receive product from Japan. Today's supply chains are global and complex networks of enterprises that aim to deliver products in the right quantity, in the right place, and at the right time in an increasingly volatile and unpredictable environment. To cope with internal and external supply chain instability and disruptions, supply chains need to be resilient to survive. A supply chain's ability to collaboratively share information with its supply chain partners is one of the most important factors that enhance a supply chain’s resilience. Cloud based supply chain management (SCM) creates a platform that enables collaborative information sharing that helps to identify, monitor and reduce supply chain risks, vulnerabilities and disruptions. However, supply chain academics and practitioners are at its infancy in understanding the capabilities of cloud based supply chains and its impact on resiliency. The goal of this dissertation is to explore how cloud based SCM make supply chains more resilient to disruptions. To achieve this goal the present research addresses the following fundamental research question: What is the impact of cloud based supply chain management (SCM) on supply chain resilience? To address this research question, this dissertation is comprised of three separate but interrelated essays. The first essay uses the systematically literature review (SLR) method to provide clear definitions of supporting constructs of supply chain resiliency (SCRES), classify the capabilities of SCRES, and identify existing research gaps and future SCRES research ideas. The second essay applies resource-based view (RBV) and dynamic capabilities as the theoretical lens to investigate the role of cloud based SCM in establishing SCRES. The second essay develops a theory-driven, conceptual model to illustrate and explain the relationships among cloud based SCM, SCRES, and the supply chain capabilities identified in the first essay. The third essay uses systems dynamics theory to develop two novel casual loop diagrams (CLD) and its equivalent systems dynamics (SD) models to quantitatively analyze the impact of cloud based information sharing on supply chain performance. A hospital supply chain is used as an illustrative example to show the positive impact on performance. Lead-time, inventory spend, and customer service levels are the comparative performance metrics used in this essay and are consistent with the findings of essays 1 and 2. One CLD and its equivalent SD model represent a traditional on-premise hospital supply chain information sharing platform and the other represent a cloud based hospital information sharing platform. The SD models simulate and compare the performance of the traditional and cloud based hospital supply chain platforms.

Introduction: Supply chain management has been defined as, "..a set of approaches utilized to efficiently integrate suppliers, manufacturers, warehouses and stores, so that merchandise is produced and distributed at the right quantities, to the right locations and at the right time, in order to minimize system-wide costs.... satisfying service level requirements.. " -- ".. integration of activities ..through improved supply chain relationships to achieve sustainable competitive advantage.. " -- "..coordination and collaboration with channel partners.. coordination of process and activities.. " [53] "..from the ore mine to the trash can... the production and distribution network that encompasses the sourcing, manufacturing, transportation, commercialization, distribution, consumption, and disposal of goods.. " -- "...flow of requirement information from buyer to seller which triggers all later activities, the movement of goods from sellers to buyers, transfer of ownership rights from seller to buyer and payment from buyer to seller. " The above definitions offer a broad spectrum of supply chain orientation and management choices available to companies. They could vary from a transactional orientation that is focused on low cost acquisition; to one where stronger relationships are established with key suppliers and customers in an effort to optimize and capture synergies; onward to a partnership orientation that is focused on supporting mutual goals for a sustainable competitive advantage. Making the right choice is essential. It can have a significant impact on a company's balance sheet and income statement. GSCF and SCOR are two popular process frameworks in supply chain management [36]. Corporate strategy is the starting point of the GSCF framework, with the operational aspects of customer relationship management and supplier relationship management linked to the strategy. Its process metrics are related to EVA. On the other hand, the SCOR framework focuses on transactional efficiency by integrating operational activities such as purchasing, operations, and logistics. It benchmarks process metrics to improve operational efficiency.

Ethanol can be made from agricultural residues like wheat straw and from crops dedicated to energy use, like switchgrass. We study the logistics aspects of this transformation and determine the main characteristics of the supply chain making ethanol from cellulose. Important to the final acceptability of ethanol as a transportation fuel is both the economics as well as the environmental aspect of using ethanol. In this study we analyze the buildup of cost as biomass is transformed into fuel. We also look at all the steps involved and describe them from a supply chain perspective We have found that the main cost components in the cellulosic ethanol production are biomass production, harvesting and ethanol refining. We have also found that the main factor in reducing the overall production cost is the biomass to ethanol conversion factor. The development of new technologies to convert biomass into ethanol becomes a critical issue to achieve the cost targets imposed in order to make ethanol more competitive with other sources of energy such as fossil fuels. An increase in the current conversion factor of 42% could potentially yield to a decrease of nearly 15% in the: total production cost of cellulosic ethanol.
(cont.) Other factors such as increasing the refining plant size and biomass yield can also help to reduce the production cost but we found its impact to be lower than that of the conversion factor. Finally, we also performed a strategic analysis of the entire supply chain to determine how is this industry likely to develop and who will have more bargaining power and therefore will realize most of the value and profits in the supply chain. Our analysis shows that in such a dynamic scenario as in the alternate energy industry, the best option is to build sustained advantage by strong alliances with different partners within the supply chain.

Abstract:

Purpose: This research aims to enhance the current understanding and knowledge of the demand-supply chain management (DSCM) concept by determining its elements, benefits, and requirements, as well as by analyzing key elements of the concept. Methodology: This research has utilized the case study strategy and the survey strategy, however, the case study strategy dominates. The case study research has involved five companies originating from Sweden and the collection of empirical data mainly from in-depth interviews with key persons representing senior and middle management. The survey research targeted the largest firms in Sweden and Finland and empirical data was collected through an online questionnaire. Findings: This research has established that the main elements of DSCM include market orientation, coordination of the demand and supply processes, viewing the demand and supply processes as being equally important, as well as value creation, differentiation, innovativeness, responsiveness, and cost-efficiency in the demand and supply processes. It has also been revealed that the main benefits of DSCM include enhanced competiveness, enhanced demand chain performance, as well as enhanced supply chain performance, while the main requirements of DSCM include organizational competences, company established principles, demand-supply chain collaboration, and information technology support. A key element of DSCM further investigated is differentiation focused supply chain design. It has been shown that these efforts can be organized into a process of five stages. In addition, it is important that this process is addressed in parallel with the new product development (NPD) process, that information is exchanged between them, and that they are directed on the basis of the same segmentation model. Another key element of DSCM further investigated is coordination between NPD and SCM. This research has identified several significant linkages between these management directions, which motivate the use of an integrative NPD process where the NPD functions are aligned with the main supply functions in the company and other sales-related functions supporting the commercialization. A final key element of DSCM further investigated is the significance of regarding the demand processes and the supply processes as being equally important. This research has revealed that logistics outsourcing can be risky, if it results in the supply processes being considered less important. Nevertheless, if senior management regards the outsourced processes as equally important as the in-house processes, the effect of logistics outsourcing on company strategies and direction in SCM could be reduced and logistics outsourcing could instead provide an opportunity to improve the design and differentiation of the supply chain. Research limitations/implications: This research has proposed, described, and further analyzed a demand-supply oriented management approach. Such a management approach stresses that the demand processes and the supply processes have to be coordinated and directed at an overlying level, in order to gain and sustain a competitive advantage in competitive and fragmented markets. This research is mainly explorative in nature, and more empirical data, from similar and other research settings, is needed to further validate the findings. Another limitation of the research is that it is essentially limited to Swedish companies (even if some Finnish companies are involved in the survey), however, many of the case companies have a large international presence and are among the top three in their industries, facts which provide some grounds for generalization. Practical implications: This research provides researchers and practitioners with insights into how to develop a demand-supply oriented business. It shows that companies should organize themselves around understanding how customer value is created and delivered, as well as how these processes and management directions can be coordinated. In order for this to occur, the demand and supply processes must be considered as being equally important and the firm needs to be managed jointly and in a coordinated manner by the demand- and supply-side of the company. It is also important that value creation is considered in both the demand and supply processes. Originality/value: Despite strong arguments from both researchers and practitioners for a demand-supply oriented management approach only a minority of companies appear to have effectively coordinated the demand and supply processes. This might be influenced by the lack of research examining how the demand and supply processes can be coordinated, what benefits can be gained by coordinating them, and what requirements are necessary to succeed. This research contributes by investigating these types of aspects further.

Cette thèse contribue au déploiement de l’infrastructure liée à l’énergie renouvelable qu’est l’hydrogène, en proposant de nouvelles stratégies basées sur des approches d’optimisation. Un état de l’art sur la conception de la chaîne logistique de l’hydrogène est préalablement réalisé, et permet d’identifier dans la littérature deux perspectives de recherche. La première concerne la couverture de la chaîne logistique globale, qui n’est pas assurée, d’une part en amont au niveau de la localisation des fournisseurs de matières premières et de l’approvisionnement des centres de production (aspect transport), d’autre part en aval au niveau de la localisation des points de distribution (stations-service) et de leur approvisionnement (transport). Pour intégrer ces composantes, un nouveau modèle de planification est élaboré. Il fusionne les modèles classiques, plus précisément un modèle de HSCND (Hydrogen Supply Chain Network Design) au niveau central, c’est-à-dire au niveau de la production et du stockage, et un modèle de HSRP (Hydrogen Refueling Station Planning) en bout de chaîne, qui considère la distribution. Ce nouveau modèle intègre également la prise en compte des sources d’approvisionnement. Il est exprimé sous forme d’un programme linéaire en nombres entiers mixtes, avec pour objectif la minimisation du coût de l’hydrogène à la pompe (LCOH). Son intérêt est validé par une étude de cas représentant la Franche-Comté en France.La seconde voie explorée est l’intégration des niveaux de décision stratégique et tactique. Il s’agit d’optimiser simultanément la localisation des stations-service et des tournées de ravitaillement de ces stations, en considérant comme actées les décisions prises précédemment depuis les sources d’approvisionnement jusqu’aux centres de production en hydrogène. L’objectif est de maximiser la capture du flux de demande, tout en minimisant le coût quotidien total. Deux algorithmes approchés sont développés pour résoudre ce problème, l’un basé sur une recherche adaptative de grand voisinage, l’autre sur un algorithme génétique. Le modèle et les algorithmes proposés sont appliqués à la région Bourgogne Franche-Comté en France
This thesis contributes to the deployment of the hydrogen infrastructures by proposing new strategies based on optimization approaches. A state of the art on the design of the hydrogen supply chain has been previously carried out, and allows to identify in the literature two research perspectives.The first one concerns the coverage of the entire supply chain, on the one hand upstream at the level of the location of raw material suppliers and the supply of production centres (transport aspect), and on the other hand downstream at the level of the location of distribution points (refueling stations) and their supply (transport). To integrate these components, a new planning model is developed. It merges the classical models, more precisely an HSCND (Hydrogen Supply Chain Network Design) model at the central level, i.e. at the level of production and storage, and an HSRP (Hydrogen Refueling Station Planning) model at the end of the chain, which considers distribution. This new model also integrates the consideration of supply sources. It is expressed as a mixed number integer linear program, with the objective of minimizing the least cost of hydrogen (LCOH). Its interest is validated by a case study representing Franche-Comté in France.The second research area explored is the integration of the strategic and tactical decision-making levels. The aim is to simultaneously optimize the location of refueling stations and the routes to supply these stations, by considering as actuated the decisions previously taken from the supply sources to the hydrogen production centers. The objective is to maximize the refueling demand flow captured, while minimizing the total daily cost. Two metaheuristic algorithms are developed to solve this problem, one based on an adaptive large neighbourhood search, the other on a genetic algorithm. The proposed model and algorithms are applied to the Bourgogne-Franche-Comté region in France

Abstract:

Thus, the best results in business are achieved by companies using the concept of integrated logistics, which allows you to combine the efforts of the managing personnel of the company, its structural divisions and logistics partners in a single chain: procurement - production - distribution - sales - service. The principles and methods of integrated logistics are aimed at obtaining optimal solutions, in particular, minimizing the overall logistics costs of the company. Reducing all types of costs allows the company to free up financial resources for additional investments in warehouse equipment, information and computer systems, advertising, marketing research, etc. Optimal logistic solutions can be obtained by the company’s management not only by the criterion of minimum total costs, but also by such key indicators as the lead time and the quality of the logistics service.
In recent years, the interest of scientists and practitioners in the problems of logistics has been growing. The globalization of the market of goods and services, as well as global changes in information technology, require ensuring the clarity of physical supply flows as a necessary condition for the mandatory continuity of business processes. The methodological apparatus of logistics has proved the universality of its use in streamline process optimization in all areas of the national economy. Integrated logistics planning helps to increase the economic sustainability of companies in the market due to logistical coordination, which allows to find compromises between the functional units of the company and ensure its integrated interaction with the external environment.

Abstract:

In production planning for strong seasonal demand products, it is uneconomical to configure the supply chain for throughputs equivalent to the demand peaks. Instead, a holistic approach to supply chain optimisation is adopted where forward demand forecasts drive the production planning process. In this thesis, the medium-term supply chain planning components of forecasting, production planning and evaluation are addressed through studies on a paints production facility. With a large number of specialised products, family-level forecasting is adopted for its simplicity and practicality in applying forecast techniques, coupled with its benefits on the inception of new products into markets. A time-series component was incorporated into traditional clustering techniques for segmenting products into families. The dominant cluster profiles identified are attributed as the seasonal component for the subsequent generation of demand profiles. In multi-purpose batch plants, production planning involves the twin decisions of batch sizing and lot sizing, often performed in series. This campaign is optimised through augmenting the batch sizing operation within a lot-sizing model. In the Mixed Integer Linear Programming model developed here, the degrees of freedom are the monthly batch sizes of each product, integer number of batches of each product produced each month, amount of monthly overtime working and outsourcing required as well as the time-varying inventory positions across the chain. Values for these are selected to balance the trade-offs in batch costs and inventory costs as well as the overtime and outsourcing costs. The final section sees the development of stochastic, dynamic supply chain models to predict the effect of different inventory policies, taking into account forecast accuracy, as derived from clustering. Using Monte Carlo based simulations, the various supply and production decisions are assessed against process manufacturing performance indicators. These planning components are then reconfigured to derive an optimal paints supply chain.

Abstract:

The developed work is motivated by the hypothesis that the presented Supply Chain Business Model is a practical and comprehensive approach to support not only operational day-to-day business decisions, but most importantly strategic and long term decisions that may define the success and the longevity of a business. Conceptually, the Business Supply Chain Model developed in this thesis replicates the behaviour and decision making of the different agents in a supply chain, and an Optimisation Module determines the optimised parameters that maximise the overall business profit, whatever scenario it may be. In the optimisation module, a Genetic Algorithm was used to determine the best equation parameters for each individual agent that optimise the overall supply chain profit. Furthermore, several business case-scenarios are presented and the findings highlighted. These case-scenarios prove that: the HC model is robust when subjected to predictable or unpredictable causes of variability; the bullwhip effect can be reduced significantly by applying GA as the optimisation tool; the improvement of profits needs to be evaluated at a global scale, independently of the individual agents’ profit; impact of supply shortages in the SC ; retail expansion analysis; delivery patterns change impact in profitability; impact of sourcing decisions in the SC profitability; model suitability for seasonal vs. non-seasonal products. The SC Modelling framework generic and globalising approach means that is easily applied and transposed to any other business realities and it can be easily changed to reflect other SC scenarios. The costing model associated means that, at any point in the network, all costs and profits can be easily measured. For the first time the shelf-life of a product captured and losses of product due to BBE dates, quantified. In this model the optimisation methodology runs parallel to the developed simulation tool, so the optimisation should be only run for new scenarios.

Abstract:

In humanitarian aid organisations, due to increasing pressure from donors, there is an urge to professionalise and optimise the way supply chains are managed. In the commercial companies there is strong evidence that focusing more on supply chain management can improve efficiency and lead to major cost savings which makes it very interesting for humanitarian aid organisations to adopt practices from the commercial world. The concepts of agility and leanness are said to prepare organisations to respond quickly to fluctuating customer demand (agility) and to increase efficiency through waste elimination and process optimisation (leanness), two properties which are required by humanitarian and commercial organisations likewise. In the commercial context agility and leanness are often combined as a le-agile strategy which is also applicable for humanitarian supply chains where the distinct humanitarian supply chain stages – preparedness, response, and reconstruction – follow different objectives and operate in different environments. Based on existing literature, this thesis identifies and examines the combination of lean and agile strategies with the different humanitarian supply chain stages. The combination possibility for a le-agile strategy is based on the base-surge demand approach from commercial literature. Moreover, agile and lean supply chain characteristics as well as practices how to achieve these characteristics are identified and illustrated in a theoretical framework. The empirical, qualitative research using a single-case study strategy further explores the supply chain practices of the Georgia Red Cross Society (GRCS) during the armed conflict in 2008. These lean and agile practices were studied by looking at preparedness, response and recovery stages related to the event, as well as the new preparedness phase, emerged after the armed conflict. The key findings indicate that lean practices are performed by the case organisation in the preparedness stage and to some lower extent in the reconstruction stage. Agile practices were evidenced in the response stage of the armed conflict. Overall, the findings support the theoretical propositions made prior to the empirical research. However, in the case of the studied organisation, the findings indicate that not all lean practices, identified from the commercial supply chain literature, were applied in the preparedness and reconstruction stages likewise. Nevertheless, in general there was a tendency for using lean practices in both stages of humanitarian supply chain. Another finding indicates that lean and agile practices are strongly linked and support each other. This was clearly reflected in an interconnection between preparedness and response stages, whereas implementation of efficient lean practices during the preparedness stage supported a quick and agile reaction to the armed conflict in the response stage. Additionally, it was found out that the reconstruction and preparedness stages of the GRCS humanitarian supply chain are connected through an iterative process of continuous learning and improvements. This thesis contributes to existing literature by providing empirical proof for the existence of lean and agile strategies in the preparedness, response, and reconstruction stages of the case organisation’s humanitarian supply chain. These results also support the possibility to use the commercial base and surge demand model for combining lean and agile strategies with the different humanitarian supply chain stages, which represents an under-investigated field in existing humanitarian supply chain literature.

The wide range of the petroleum industry's products as well as the varied value of these products coupled with the global nature of the petroleum industry presents both challenges and opportunities within the petroleum supply chain. It is along this supply chain that challenges for creating value for the customer exist as well the opportunities for reaching this goal. Value chain analysis methodology has been hailed as being capable to lend itself to process improvement challenges faced along supply chains. To achieve this objective, a case study method was used to collect and analyse data. This dissertation identifies and follows one of the supply chains of a petroleum company operating in South Africa to investigate how value chain analysis can be implemented along its supply chain.

Abstract:

This dissertation is about supply chain management. Some authors have used the term to describe a strategic, inter-organisation issue, others authors to discuss an alternative organisational form to vertical integration. Much of the operations management literature uses the phrase to describe the planning and control of materials flow internally within a company or externally between companies. This work develops a definition of supply chain management. The empirical research tests hypotheses relating to gaps in customers' and suppliers' perceptions of requirements and performance in supply chains, against a set of performance dimensions. The hypotheses are tested in four automotive aftermarket supply chains, two of which are in Spain and two in the UK. All four chains have similar structures and include a manufacturer, an area distributor, a local distributor and ten installers, or garages. Qualitative and quantitative analysis show significant :differences between different types of gaps in perceptions; suppliers in the chains do not recognise the 'degree of customer dissatisfaction in existence. A positive correlation is shown to exist between the amount of misperception in the chains about performance and the amount of customer dissatisfaction. It is also shown this customers are more dissatisfied with some performance dimensions than others. In these supply chains, customer dissatisfaction and misperception of performance both significantly increase upstream i.e, downstream customers are more satisfied and there is less misperception in downstream relationships about performance levels. This effect is compared to the industrial dynamics "Forrester Effect". The work develops the concept of supply chain management into a broader, holistic concept of interorganisation operations management. It contributes to operations management by (i) developing the concept of supply chain management (ii) improving knowledge about relationships in supply chains (iii) identifying the significant role of performance (iv) improving knowledge about the implication of position in a supply chain (v) integrating related literatures, notably service management, purchasing, industrial dynamics and logistics.

Abstract:

The amplification of demand variation up a supply chain widely termed ‘the Bullwhip Effect’ is disruptive, costly and something that supply chain management generally seeks to minimise. Originally attributed to poor system design; deficiencies in policies, organisation structure and delays in material and information flow all lead to sub-optimal reorder point calculation. It has since been attributed to exogenous random factors such as: uncertainties in demand, supply and distribution lead time but these causes are not exclusive as academic and operational studies since have shown that orders and/or inventories can exhibit significant variability even if customer demand and lead time are deterministic. This increase in the range of possible causes of dynamic behaviour indicates that our understanding of the phenomenon is far from complete. One possible, yet previously unexplored, factor that may influence dynamic behaviour in supply chains is the application and operation of supply chain performance measures. Organisations monitoring and responding to their adopted key performance metrics will make operational changes and this action may influence the level of dynamics within the supply chain, possibly degrading the performance of the very system they were intended to measure. In order to explore this a plausible abstraction of the operational responses to the Supply Chain Council’s SCOR® (Supply Chain Operations Reference) model was incorporated into a classic Beer Game distribution representation, using the dynamic discrete event simulation software Simul8. During the simulation the five SCOR Supply Chain Performance Attributes: Reliability, Responsiveness, Flexibility, Cost and Utilisation were continuously monitored and compared to established targets. Operational adjustments to the; reorder point, transportation modes and production capacity (where appropriate) for three independent supply chain roles were made and the degree of dynamic behaviour in the Supply Chain measured, using the ratio of the standard deviation of upstream demand relative to the standard deviation of the downstream demand. Factors employed to build the detailed model include: variable retail demand, order transmission, transportation delays, production delays, capacity constraints demand multipliers and demand averaging periods. Five dimensions of supply chain performance were monitored independently in three autonomous supply chain roles and operational settings adjusted accordingly. Uniqueness of this research stems from the application of the five SCOR performance attributes with modelled operational responses in a dynamic discrete event simulation model. This project makes its primary contribution to knowledge by measuring the impact, on supply chain dynamics, of applying a representative performance measurement system.

Abstract:

Research questions 1. What kind of risks in the supply side of HUAWEI supply chain can be identified? 2. How can supply side risks of HUAWEI supply chain be assessed? 3. How can supply side risks of HUAWEI supply chain be mitigated? Purpose This paper describes supply side risks in HUAWEI in China, the types of risks identified, provides guidelines for assessment of these risks and suggestions for mitigation. Methodology In order to answer above research questions empirical data have been collected through observations, interviews at with logistics managers of HUAWEI in China, and from the official documents, annual reports and authentic web pages of the HUAWEI. Theoretical framework has been built through scientific articles, peer reviewed journals, authentic web based documents, and textbooks. The information is then assessed and analyzed, which result in conclusion and recommendations for the company. Conclusion There can be four major risks identified on the supply side. Manufacturing risk, logistics risk, information risk and inventory risk. The manufacturing risk include risks related to production, skill, and quality. The logistics risk further include delivery risk, lead time risk, and transportation risk. Production risk and skill risk are critical and they can be avoided by enhancing risk awareness, evaluating production feasibility, strengthen staff training, investing in high skills, strengthening R&D, and analysis of the external environment. The quality and inbound delivery risks can be reduced through supplier inspection and establishing good supplier relations. Lead time risk and inventory risk can be reduced by vendor based managed inventory system and mass customization. Meanwhile, transportation risk can adopt risk transfer strategy. The information risk can be reduced by increasing information sharing levels and adopting modern communication technologies.

Full text

Abstract:

The concept of supply chain management has become an important issue for companies today in order to keep or gain competitive advantage. It is all about managing your supply chain to reach the highest possible efficiency and increase profits through cooperation with your supply chain partners. A supply chain is however vulnerable to several threats, or risks, that decreases the overall efficiency and influences the business performance.

The purpose of this thesis is to identify the internal risks that can be found in a basic internal supply chain in order to make an assessment of their manageability and impact using a specific case. To do this a case study of Thule Trailers AB in Jönköping was conducted. Thule Trailers AB chose to offshore their main production of components to Poland in 2003, so the company’s internal supply chain was expanded outside of Sweden. This research looks closer at the interactions between Thule Trailers AB in Jönköping and their internal supplier plant in Poland. The research was conducted using a qualitative method with several interviews with representatives in both Jönköping and Poland, during which a number of internal risks were identified in Thule Trailers AB in Jönköpings’ internal supply chain.

The conclusions made are that the internal risks identified, i.e. communication risks, quality risks etc, might not have as great an influence on the company as would external risks, they can however in comparison be managed. The findings suggest that the issues with e.g. quality and delivery basically come down to insufficient communication inside the internal supply chain.

Another conclusion that could be drawn is that since the internal risks in the internal supply chain all are ripple effects, its source is almost always external, which implies that their avoidance is difficult. At least they cannot be eliminated completely by the company itself, it needs to be done in cooperation with the company’s external supply chain partners.

There is potential to solve most of the internal problems that can be managed internally if both parties are prepared to put some real effort into reducing the risk sources. The risks are manageable and need to be managed to reduce the impact it has for the customer and end customer in turn. The authors of this thesis believe that for a company to be successful, the end customer has to be prioritized in almost every situation, and this goes for all of the members in the supply chain, especially the internal ones.

Abstract:

A disruption to the supply of input materials is one of the main threats to manufacturing supply chains. Trade wars, natural disasters, pandemics, cyber-attacks, sudden changes in cost and quality, machine breakdowns and transport accidents are among the causes of disruptions to supply chains. The supply chain is made up of several interconnected parties, where a product or service moves from raw material suppliers through to manufacturing, before its final delivery to customers. The extent and complexity of such interconnections can significantly increase the vulnerability of the supply chain system to disruptions. A disturbance to one party may propagate to other nodes and cause major disruption and financial losses for the whole supply chain. Many causes of supply disruptions are beyond the control of supply chain managers, therefore the best way to manage them is to be proactive. Supply chain managers undertake a risk management process to prepare the supply chain for mitigating the possible impacts of disruptions. Managers have several options to control their exposure to disruption risks. Two main options available are stocking material in inventory and maintaining a portfolio of suppliers. This thesis focuses on managing supply disruption risks in supply chains. It aims to assist the supply chain managers to mitigate the risk of supply disruptions and the corresponding effects these will have on profits. This thesis makes its contribution in three broad steps: (1) Development of a decision-making model to efficiently mitigate the likelihood of a supply disruption. The model determines an optimal supplier portfolio through continuous monitoring of supply risk indicators that detects early warnings of a supply disruption. Risk indicators are based on a supplier’s product price, financial and production stability, and quality. Using an integrated system dynamics and portfolio optimisation solution approach, the model assists decision-makers to rebalance their supplier portfolio in response to early changes in supply risk indicators over a planning horizon. (2) Development of an optimal inventory strategy model from the perspective of a manufacturer in a supply chain. This model aims to determine the optimal inventory strategy based on the expected supply price and product market demand over a planning horizon. The model seeks to maximise the manufacturer’s profit at the beginning of a planning horizon, rendering the inventory option as managerial flexibility to mitigate the undesirable effects of supply disruptions. (3) Development of a decision-making model to determine an optimal contracting strategy, sourcing policy and inventory management at each period to maximise the manufacturer’s profit at the beginning of the planning horizon. This third step allows for the concurrent application of managerial flexibilities to manage supply chain risks. This model adopts the view of a manufacturer in a supply chain with two suppliers. It provides the manufacturer with the optimal allocation of supplies, including an optimal long-term contract position with one supplier at the beginning of the planning horizon. The model also enables the decision-makers to find the optimal inventory strategy at each period to mitigate the effects of supply disruptions and maximise profit for the manufacturer. To develop the decision-making models in steps (2) and (3), this thesis applies a real options analysis method. An American-style option valuation method is used to solve the optimal inventory, sourcing and contracting strategy under uncertain supply price and product demand. This thesis uses a least-square Monte Carlo simulation to solve the underlying dynamic programming model. The results of the modelling in step (1) demonstrate how a supply portfolio can be developed to provide higher expected profit at a certain level of risk. They also show how the optimal decision depends on the risk propensity of the decision-maker. The results of modelling in step (2) demonstrate the conditions under which inventory flexibility is valuable to a supply chain. Results show how a higher expected supply price during a disruption period and a higher expectation of disruption, increases the value of an inventory flexibility option. Expectations of early disruptions increased the value of the inventory option. Results of modelling in step (3) show how a manufacturer can balance their inventory of supplies and a long-term contract with one supplier at the beginning of the planning horizon to maximise profit.

Abstract:

Unibrands is a small company that has implemented a postponement strategy without knowing it. However, they have not implemented completely because they do not know the theories behind it. This report is an attempt to understand and analyze the problems of the implementation of postponement in the supply chain of Unibrands, in terms of examining the theoretical succeeds factors of postponement implementation in the case of Unibrands.The purpose is to determine what type of postponement strategy the supply chain use and what factors can hinder the use of postponement strategy in a SME fashion supply chain by applying an qualitative research approach. The collection of empirical data was through the interview guide approach in which we used meetings and telephone interviews with people representing Unibrands and their contact trading company. The results of this research can be concluded in few perspectives. Unibrands is imple-menting postponement in an improper format, with the results of several gaps in the supply chain related to the success factor in postponement. The request for the fully customization in colors and materials, the bottleneck of relationship developing which is caused by factory manager, complicated procedures for sample testing, and lack of knowledge of different relationships in the supply chain. Postponement is never perfect, but for Unibrands some problems could very well hinder the efficiency in the supply chain. Solutions are proposed to solve the problems in chain. The proposals suggest re-lationship improvement and information sharing. In addition, culture adaptation by in-volving the right people in the right process.

Abstract:

Market globalization and steep competition are increasing the need for more efficient and effective strategies in meeting evolving market demands. Adopting a more integrated approach to supply chain relationship management has been increasingly viewed as a way of meeting changing customer needs. This thesis work explores lean and agility frameworks as tools for achieving supply chain integration. Different aspects of the concepts of lean and agility and their applications in the supply chain are presented based on theoretical literature. Thus, this thesis seeks to point out the impact that the concepts of lean and agility can have on the supply chain as a whole. Four companies have been investigated in connection to the level of awareness, perception, and practical application of these tools in their supply chain. To this end, information was collected in a survey questionnaire from these four companies and supported by an interview. The results show that lean and agility are important tools to achieve supply chain integration, but respondents are yet to fully achieve the transition to lean/agile enterprise. It could be said that lean/agile supply chain is still more in theory than in practice. The level of awareness to market changes is high but there seem to be no specific way in achieving integration in the supply as there is wide variation in the way one company achieves it with respect to another. Generally, respondents are implementing lean/agile principles in cooperation and collaboration with suppliers and customers, demand pull system, and using combination of strategies. However, it is clear that adequate market information is required when trying to fit lean/agile principles into supply chain strategy. Furthermore, all respondent recognise the need for change to satisfy customer need, but the respond to change vary from one company to another. Also, there is a gradual shift from traditional focus solely on cost and profit to customer relation relationship management and customer satisfaction. Consequently, companies are organizing themselves around the customer who pulls goods and value from the producer of the goods.

Full text

Abstract:

This thesis identifies the role of trust in the supply chain relationship on supply chain performance and organisation performance. An extensive review of literature identified a lack of empirical research to fill a gap in supply chain and operations management knowledge and this gap is mainly related to identification of the role that trust has on performance. This thesis considers this gap with other relevant issues identified through the literature. It presents a research framework formulated to tackle the research problem and reports an attempt to fill the existing gap through empirical research. The thesis contains analyses of three case studies related to three different territories, namely; Oman, United Arab Emirates (UAE) and State of Qatar. The case studies encompass large and medium size organisations from three different industrial settings. In Oman, the case study is related to oilfield services and the oil production industry while in UAE the case study is related to real estate and the property development industry, and the case study in Qatar is related to the chemical industry. In addition to identifying the influence of trust in supply chain relationships on organisation performance and supply chain performance, the research considers the influence of the duration of the supply chain relationship on trust development in the relationship. Additionally, it explores the impact of trust on the avoidance of the bullwhip effect in the supply chain and shows through empirical evidence the role of trust in minimising supply chain risk. Consideration is given to the impact of different territory and different industrial settings on the trust/performance relationship. Triangulation of research approaches and methods is utilised in this research to enrich the research findings by exploiting the advantages of each approach and method advantages while reducing the disadvantages through complementarities between them. The results of this thesis indicate that the supply chain parties should adopt trust in their relationship whenever considering supply chain performance improvement, organisation performance improvement, and overcoming risk.

Abstract:

The purpose of this thesis was to understand how sustainable supply chain management processes are managed in practice given the variations in sustainability principles. The Global Supply Chain Forum's Supply Chain Management Framework was used to focus the study by examining how its elements (network structure, management component and business processes) interact with sustainability. There is evidence of a paradigm shift as evidenced in how the two concepts of sustainability and SCM merge. This justified the framework's elements being re-examined in the context of sustainability to understand how the elements change. However, there is no body of research that examines processes unique to SSCM. Furthermore, knowing how to manage these in practice, required an understanding of why and how different stakeholders behave. This needed a network view of multiple stakeholders, but limited research exists on end-to-end supply chain networks. Moreover, there is limited research on the management of diverse sustainability principles and the coordination of multiple stakeholders engaged in these. A single explanatory case study of a network and its nodes was selected as a method to explain how stakeholders behave through the proximity of network determinants. Two units of analysis (the network and the organisation) were used to examine organisational orientation and stakeholder network theory. This resulted in theoretical propositions and conceptual framework that explained a spectrum of sustainability principles, a model of sustainability business processes and phases of management, and archetypes of practice and complimentary typologies. The main contributions of the research were twofold: It mapped and modelled an end-to-end supply chain network and provided a SSCM framework. In doing so, it built theory by offering a model of key business processes in SSCM, taxonomic classes of SSCM practices, eco-centric theory, pre-competitive collaboration, concurrence, and leveraging interorganisational clusters to manipulate sustainability principles.

Abstract:

The purpose of this research was to find the relationship that exists between supply chain strategies and supply chain management practices at manufacturing companies. A sample of 195 firms in Colombia was used. Data analysis was performed in three phases. Initially, an exploratory factor analysis was carried out to identify the dimensions underlying each construct and derive, from the literature, a parsimonious configuration of supply chain management strategies and practices. Then, using a confirmatory factor analysis, internal consistency and degree of fit of the measurement models was evaluated. Finally, a structural equation model was built to test the formulated hypotheses (CMIN/DF=1.865, RMSEA=0.067, CFI=0.884, IFI=0.888, PNFI=0.623). Results in terms of correspondence were dissimilar, as a positive and statistically significant link was found between the constructs lean supply chain strategy and relationship with supply chain partners (H1a, y11=0.750, p<0.01), lean supply chain strategy and information management (H1b, y21=0.705, p<0.01) and between agile supply chain strategy and relationship with supply chain partners (H2a, y12=0.420, p<0.01). However, links between lean supply chain strategy and postponement (H1c, y31=-0.182, p>0.01), agile supply chain strategy and information management (H2b, y22=0.201, p>0.01) and agile supply chain strategy and postponement (H2c, y32=0.227, p>0.01) were not supported by empirical evidence. This allowed concluding that planning and formulating a specific supply chain strategy must involve a joint deployment of the practices appropriate for materializing it and that not all supply chain management practices support fulfilling the goals defined for the chain. For future work, including an analysis of the effect of variables such as demand uncertainty, company size or type of industry in the evaluated relationship is suggested. The importance of longitudinal measurements or evaluations with a qualitative approach to understand the phenomenon being studied is also mentioned.

Abstract:

This master thesis describes and proves how companies can improve their operational performance and supplier relationships by using modern collaborative and planning practices, specifically the Collaborative Planning Forecasting and Replenishment (CPFR) concept. The theoretical part depicts main developments in supply chain planning over time, shows common challenges in the world of supply chain and offers possible solutions in terms of collaborative supply chain planning practices. The practical part analyzes the CPFR process between one of the leading providers of telecommunications services T-Mobile and its major mobile handset supplier Nokia. The concluding part defines gaps between an ideal to-be process of supply chain collaboration and the status quo process. Status quo benefits of current CPFR processes are described as well.

Abstract:

It is of increasing importance to in the most effective possible way, manage and control all the transactions of raw materials, products and information that are exchanged between an organization and all its operators. These flows and the need for strategy and managing the processes of planning, implementing and control of the supply chain, has given name to the concept supply chain management. Supply chain management involves all movement and storage of raw material, and all the processes that is needed to manufacture a product from origin to consumption. Globalization, technology and increasing time and quality-based competition are all driving forces behind the concept and reasons for an increasing interest in supply chain management.

The purpose of this essay is to by using a qualitative case study examine which decisive success factors that can be identified for effective supply chain management. We have compiled different theories on the subject to use for analyzing a case study Li & Fung, who is a successful supply chain management company. We intend to give a detailed description of this complex concept and identify decisive success factors for effective supply chain management.

The study shows two prominent aspects for effective supply chain management; (1) Leadership and (2) control of the supply chain.

Abstract:

In this study, carbon dioxide emissions resulting from transportation are assessed, carbon emission reduction opportunities in the current service supply chain design of Cisco Systems, Inc. are explored. Among these opportunities, changing transport mode from a high-carbon transport mode to a low-carbon transport mode is found to be the most promising option and is scrutinized. The effect of transportation mode change on carbon emission and expected total cost are scrutinized by developing a mathematical model that minimizes expected total cost subject to aggregate fill rate constraint. Furthermore, a second model that minimizes the expected total cost under aggregate expected fill rate and carbon emission constraints is developed. In this model transportation mode choice decisions are integrated into inventory decisions. Since it is difficult to make transportation mode selection for each individual item, the items are clustered and transportation mode selection is made for each cluster. Therefore we propose two clustering methods that are k-means clustering and an adopted ABC analysis. In addition, a greedy algorithm based on second model is developed. Since currently there are no regulations on carbon emissions, in order to examine possible regulation scenarios computational studies are carried out. In these studies, efficient solutions are generated and the most preferred solutions that have less carbon emission and lower total cost among all efficient solutions are examined.

Abstract:

Oriflame is a famous international direct sale cosmetics company with complicated supply chain operation but it lacks of a product classification system. It is vital to design a product classification method in order to support Oriflame global supply planning and improve the supply chain performance. This article is aim to investigate and design the multi-criteria of product classification, propose the classification model, suggest application areas of product classification results and introduces the product classification system into Oriflame ERP system. The research scope is defined within Oriflame supply chain from the order placed to suppliers by Global Supply department to the products received in Global Hubs.Investigation approaches in this article including information collection, multi-criteria integration, and quantified analysis. In addition, sample calculation and test to stakeholder departments have been done after the proposal of product classification system.The product classification applies a cross tabulate matrix to classify products into four classes (ABCD classification), it is believed that the results keep consistent at high level with both the calculation time horizons‟ increasing and the monthly forecast report update.Hence, Product Classification System is supposed to be applied in supply planning prioritization, inventory management and workforce balancing, etc.
