Full textSupply Chain Management har kontinuerligt utvecklats med bl.a. namnbyten eller nya populära strategier. Den har under modern tid varit utsatt för både möjligheter såsom hot vilka har varit följder av globalisering. Företag har erhållit möjligheterna att leverera sina produkter till kunder över hela världen men även att outsourca processer för att förenkla denna leverans. Oursourcingmöjligheten har även översatts till obligatoriska beslut för flera företag för att ens kunna erbjuda produkter till konkurrenskraftiga priser. Dessa beslut kan dock exponera en Supply Chain till olika risker, en brytning i logistikkedjan till exempel. På grund av dessa konsekvenser måste företag värdera vilken strategi som måste tillämpas för varje process i kedjan. Ska de centraliseras, decentraliseras eller outsourcas? Ändamålet med denna studie är att, baserat på insamlad data från ett case företag, kunna bestämma vilken strategi ska tillämpas när det kommer till inköp från externa leverantörer. Detta examensarbete har utfört en litteraturgenomgång på bl.a. studier om Data Mining för att berika kvalitén på den kvantitativa delen baserad på databaser från caseföretaget. Utvald litteratur förklarar olika aspekter från Supply Chain Management med involverade strategier och hur en lämplig nätverksdesign väljs ut. Målet är att utveckla ett ramverk för urval av lämplig nätverksdesign för caseföretaget samt ett ramverk för att summera litteraturens budskap till implikationer av centralisering eller decentralisering med fokus på Finans, Prestanda och Information. Urvalsramverket har därefter fyllts i av nyckelpersoner från caseföretaget för att jämföras med kvalitativa bidrag från intervjuer om styrkor och svagheter på tre utvecklade scenarios om centralisering, decentralisering eller outsourcing. Med erhållen data möjliggjordes en diskussion för att tydliggöra styrkor och svagheter för varje scenario för att kunna noggrant jämföras och skapa argument för vilket skulle väljas. Resultat och argument har generaliserats och sammanfattats i en figur där en kan tydligt se för- och nackdelar med varje scenario. På så sätt disponeras en koncis slutsats av implikationer med att centralisera, decentralisera eller att outsourca. Resultaten från urvalsramverket pekar på att decentraliseringsstrategin är den optimala för caseföretaget, detta måste dock ifrågasättas på grund av kontexten med den nuvarande spridningen av COVID-19 viruset och dess inverkan på ekonomin. Med detta i åtanke och ihopsamlade argument, drogs slutsatsen att outsourcingstrategin är den mest lämpliga för caseföretaget. Detta masterexamensarbete har således lett till förlängningen av ett urvalsramverk av distributionsnätverksdesign samt diskuterat fram och sammanfattat implikationerna av centralisering, decentralisering och outsourcing.

Full textTraditional extractive processes present stages that need modernization and optimization for enabling mining companies to warrant the effective achievement of both product quality and quantity. Such warranty, which is difficult to sustain due to the intrinsic nature of geological uncertainty, can only be achieved through an increased efficiency in the mineral supply chain. This work demonstrates the benefits of creating models of existing mineral supply chains to identify and understand the points of value creation and places for possible improvement interventions. It also gives a modeling guide, through an electronic chart, enabling users to model any kind of supply chain. The knowledge of the process path from extraction to final consumer provides a unique opportunity for managers to improve the mineral supply chain. After the model has been created, it should and must be improved. A number of techniques and good practices already in use by other sectors but not yet applied to the mining industry are identified and structured. A methodology to strategical application of these techniques in provided. The mining industry all over the world is under pressure to look for methods to improve its efficiency. This work leads the way to an innovative managerial strategy in mining that has proved itself extremely competitive in other industries. The key issue addressed in this work is how to identify a robust and risk-controlled path for the mining industry to benefit from the lean thinking approach, introducing the concept of Lean Mining.

Full textThe expansion of coal mining in the Caribbean region of Colombia not only creates environmental and health problems locally but is also a matter of global concern. Colombia, with almost 85 million tons exported, makes a large contribution to greenhouse gas emissions when the exported coal is burnt in coal-fired power plants (CFPPs) in importing countries, such as The Netherlands and Turkey. This is ever more relevant as the commitments from COP21 in Paris imply that four-fifths of carbon resources (from coal, oil, and gas) must remain under the ground. This thesis uses ecological economics and political ecology approaches to analyze the coal supply chain from its extraction in the open-pit coal mines in Cesar and La Guajira (Colombia) to the final consumption in CFPPs in The Netherlands and Turkey. It also employs the socio-environmental liability approach as an improvement over the standard externalities framework, since it allows for an explicit incorporation of responsibilities for uncompensated damages along the coal chain. The coal chain is analyzed in depth through different layers (market, physical, socio-environmental liabilities, social actors and the plurality of valuation languages) and different scales (local, national and global). In order to identify the coal chain socio-environmental liabilities and ecological distribution conflicts, 84 interviews were conducted in Colombia, The Netherlands and Turkey. Different economic valuation methods were used to estimate the value of the socio-environmental liabilities, and discourse analysis methodologies were used to analyze the plurality of valuation languages deployed along the coal chain. Results show that the socio-environmental liabilities of the coal extraction and its transport to export ports exceeds the market price of coal. The analysis of the ecological distribution conflicts reveals that the geographies of coal are anchored in environmental injustices and democratic deficits associated with both coal mining and CFPPs, and irreconcilable tensions between public health, economic gain and the political power in these three countries. The analysis of the valuation languages shows that in The Netherlands there are two main views regarding coal imports from Colombia, respectively the “Blood coal” and “Better coal” positions. The first one is concerned about human rights violations and the second one frames the question in the context of ecological modernization. In Turkey, the main debate is between the use of highly polluting domestic lignite or the import of better quality coal (anthracite from Colombia). Both in The Netherlands and in Turkey there are different degrees of concern about climate change and “unburnable fuels” which appear still to be absent in Colombia where the debate is focused on the local and national socio-environmental liabilities. This thesis concludes that the success of environmental justice actions taken along the coal chain depends on the political power of social actors and their willingness to give up, negotiate or impose their own valuation languages.

Full textThe mining sector occupies a central place in the economies of many mineral resource-rich countries, even more so in a period of demographic explosion. The economic, societal and environmental consequences of extractive activities raise several major problems, related to geological uncertainty, price volatility, polluting waste, future depletion of deposits, the socioeconomic situation and the health of local populations. Thus, the exploitation of phosphate, a vital element in plant growth, is facing important challenges that encourage mining companies to better control their industrial process throughout their supply chain. The research work presented in this thesis is part of an intervention-research conducted within a value chain of the OCP Group, world leader in phosphates. The objective is twofold: 1) to propose innovative tools and methods for the improvement of the operational and tactical decision-making process; 2) to accompany the company in the adoption of the proposed approaches. The logistic chain studied, the Northern Axis, is composed of several mining sites, processing units, chemical plants and ports for product shipment. An initial inventory of this chain led to a better understanding of its organization and to identify the main causes impacting the quality of the products: the steering by a single component and the continuous supply of internal product. To study the blending problem identified, the proposed intervention consists of an approach developed in two stages. First, the classical formulation of the blending problem was strongly adapted in a model taking into account the continuous aspect of the flows transported by pipeline, alternative ranges, the organization of the processing plants, but also the processing time. This model, called "dynamic blending", is based in a first step, on an already established scheduling of the shipment of products by pipeline (exogenous data) to find a production plan of the processing plants. In a second step, a scheduling model of these shipments is coupled to the previous model in a decision support vision. The first tests with real instances provided promising results, the dynamic blending approach being currently operational on other mining sites of the industrialist

A mineração de metais é uma atividade com elevado potencial de impacto socioambiental. Com a ocorrência de incidentes com grandes repercussões, como o que aconteceu em Mariana (MG), em novembro de 2015, com o rompimento da barragem de rejeitos de Fundão, as notícias sobre as mineradoras e seus impactos passaram a ser ainda mais visíveis ao público em geral, pela ampla cobertura dos meios de comunicação e pelas sérias repercussões em um grande número de comunidades, em pelo menos dois estados da federação. Dentro desse cenário, este estudo busca analisar a cadeia de suprimentos da mineração sob a perspectiva de uma empresa fornecedora de insumos químicos, buscando identificar como as inovações socioambientais são incorporadas por esta cadeia, fazendo-se uso da metodologia de pesquisa-ação, que possibilita ao pesquisador trabalhar como agente e observador, já que é funcionário de empresa fornecedora de insumos químicos para esse mercado, e realizar intervenção em caso específico. O ambiente de diálogo da intervenção permitiu a criação conjunta de conhecimento, aprofundou o entendimento sobre a cadeia de suprimentos de mineração e sobre as potencialidades do método de pesquisa-ação. Ao longo deste trabalho de pesquisa foi possível fazer observações sobre os mecanismos de incorporação de inovações socioambientais ao mesmo tempo em que foram buscadas formas de aprimoramento da competitividade da empresa fornecedora com produtos e um racional comerciais aprimorados conforme os achados do estudo. A pesquisa mostrou que o mercado de mineração industrial de metais mostra receptividade às inovações socioambientais, tenham sido elas demandadas pelas indústrias mineradoras, propostas pelos fornecedores ou ainda desenvolvidas de forma colaborativa entre elas. A intervenção na empresa (ação) proporcionou à fornecedora ferramentas corporativas para melhora do repertório de atributos socioambientais, utilizado pelas equipes comerciais, e suas formas de utilização quando das negociações com clientes. Um exemplo de aplicação da intervenção serviu para demonstrar que a valoração econômico-financeira dos atributos socioambientais é fator importante de sucesso na melhoria de competitividade da fornecedora.
The mining of metals is an activity with high potential of social and environmental impact. Mining of metals sector suffered from the occurrence of incidents with major repercussions, such as what happened in Mariana (MG) in November 2015, with the rupture of the Fundão tailings dam. The news about the mining companies and their impacts became even more visible to the public in general, by the wide coverage of the media and the serious repercussions in a large number of communities in at least two states of the federation. Within this scenario, this study seeks to analyze the mining supply chain from the perspective of a supplier of chemical inputs, seeking to identify how this chain incorporates social-environmental innovations. The present study makes use of the methodology of action research, which enables to the researcher to work as an agent and observer, since he is an employee of a company that supplies chemical inputs for this market, and to intervene in a specific case. The atmosphere of dialogue of the intervention allowed the joint creation of knowledge deepening the understanding about the supply chain of mining and about the potentialities of the method of action research. Throughout this research work, it was possible to make observations on the mechanisms of incorporation of socio-environmental innovations while seeking ways to improve the competitiveness of the supplier company with improved products and rationales as the study finds. The research showed that the market of industrial metal mining shows receptivity to socio-environmental innovations, whether they were demanded by the mining industries, proposed by suppliers or even developed in a collaborative way among them. The intervention in the company (action) provided the supplier with corporate tools to improve the repertoire of socio-environmental attributes used by commercial teams and their use when negotiating with customers. An example of application of the intervention served to demonstrate that the economic-financial valuation of socio-environmental attributes is an important factor of success in improving the supplier's competitiveness.

As the evolution of industry competition, Supply Chain Management (SCM) has become a popular issue for the current business environment, which emphasizes cooperation among all involved partners for achieving competitive advantage and customer satisfaction. With such condition, partners in the supply chain will require to deploy some decision support tools, such as data warehouse and data mining tools, to provide information for the business decision among the partners. However, the information in the supply chain environment is dispersive; those tools are unable to maximize effectiveness. In this study, a distributed data mining mechanism is proposed using a relationship metadata to integrate data sources derived from partners of the supply chain, thus solving the problem of excessive and various data volume in the current supply chain. Since data provided by partners is not extremely complete for traditional data mining, we can utilize peculiarity oriented data mining process to generate rules across the organizations in order for decision support and competitive advantage. Using prior relevance detection function, our mining mechanism will can discover useful rules which do not find in another mining mechanism for distributed databases. To evaluate the mechanism, a prototype system is developed to show the correctness of the mechanism. A case study with real database is applied to evaluate the performance of the study. The result has shown the usefulness of our discovered rules and difference between our mining mechanism and others.

Full textThe study explored the South African coal mining industry and it’s role players to establish the causes of the bottlenecks/constraints experienced in the coal mining industry supply chain. A qualitative research paradigm methodology was used. Both theoretical and philosophical assumptions were utilised with inferences from and references to works by other researchers to broaden the knowledge horizons for the study. Thirteen supply chain executives and professionals from the key role players in the coal mining industry were interviewed and provided invaluable input for the study. The study determined the presence of communication barriers between the industry role players in the public and private institutions that culminated in main themes and sub-themes being established from which the industry constraints were uncovered. The study identified six main constraints affecting the various role players within the coal mining supply chain and it culminated in the model that would enable the industry to minimise such constraints. To this end, the study proposes the development of an Integrated Strategy for the Development of Coal Mining (ISDCM).The model is based on the public and private partnership arrangement that would alleviate most of the prevailing constraints when implemented. The model would furthermore have the capacity to rectify most of the existing constraints. It would be funded from the commercial sector and would operate on triple bottom lines of economic, social and environmental factors, with equal weight. This is a desirable direction for the future in order to maintain sustainable development. Emanating from the study are policy and research recommendations for the South African coal mining industry, covering the coordination of the critical areas of the proposed integrated strategy for the development of the coal mining industry. Such recommendations include further research into new coal mines and power stations as well as perceptions and expectations of potential investors in the industry, among others.

Full textGlobalization makes competition in supply chain management more intense. Pressure on improving the efficiency, guarantee that goods arrive on time and reduce the cost of shipment became higher. Shipment passes through different continents and cultures, dispersed around the world and encounter different conditions and risks. These risks are unexpected events that might disrupt the flow of materials or the planned operations. It can be due to late delivery, inaccuracy in forecasting, natural disasters like hurricane and earthquake or sociocultural events like strike. An effective use of supply chain risk management methods which includes risk identification, risk assessment, risk mitigation, and risk control is important for the organization to survive. For that reason, I was part of a team in XXX organization who has a goal to develop a predictive model to predict shipment delays for company’s customers.

In this thesis we propose a platform for discovering supply-chain knowledge, which mainly focuses on industrial information in digital types of document distributing on the Web. By integrating text mining with ontology techniques, we provide a way to extract and manage document information containing knowledge, allowing businesses systematically apply and manage supply-chain related knowledge. In constructing our framework, we firstly establish an ontology based on industry-specific standard dictionaries provided by RosettaNet, experts from a specific domain construct ontology which classifies lexicons as class hierarchies that simulate the supply-chain knowledge structure. Secondly by applying the Web-content mining technique, we extract concepts and knowledge from a huge semi-structured and unstructured document collections. The extracted information (i.e. metadata) contains the required knowledge for operations of industrial businesses. That is, the text mining has the ability of extracting knowledge that has highly similarity with documents and vocabularies about industrial supply-chain. Finally, in order to unify document forms and communicate between systems in the future, the original HTML documents are transformed into XML ones and stored in the XML document database based upon the ontology framework described above. Besides, the proposed text mining technique applies a neural-net learning model for maintaining, self-organizing and updating the associated supply-chain information. The proposed platform also provides a keyword-based query interface for searching concept-hierarchy, which helps users obtain the supply-chain information by processing the extracted knowledge. In particular the part of knowledge of products and customers extracted from specific industrial supply-chain information sources can be applied in developing business knowledge management and exploring the opportunities in the B2B e-commerce markets.

The research case company is an electronic component distributor. The purpose of this research is to find the problem of logistics management and search for the relevant information with the problem, through interview and the analysis of case company’s logistics data. In order to search for the relevant information of three suppliers’ purchase return condition, we use the association rule of data mining method. The research found that the case company has three logistics problems. First, suppliers were unable to reach the goods on time. Second, there is disagreement between stock up and purchase quantity. Third, returning goods of suppliers. The three problems may influence case company’s transporting procedure, or increase logistics and stock costs. The relevant information of problems would be mined in the research, in accordance with the three suppliers’ product type and purchase employee separately. The purchase department managers could improve logistics and purchase procedures by data mining results.

Full textThe focus of this thesis is to examine the use of techniques of risk management employed by companies in Central Queensland's mining manufacturing supply chain. This is a rapidly growing industry sector supporting one of Queensland's major export industries. The specific objective of this research is to examine how companies in the supply chain employ techniques to identify, assess, and manage supply risks.
The research methodology entailed the use of in-depth interviews of companies in Rockhampton, Mackay and Yeppoon in Central Queensland. This method has been selected because of limited empirical data relating to supply chain issues in this field. Quantitative questions have been incorporated into an interview questionnaire to gain more information in the limited time available. A total of 21 interviews were conducted, and methods of qualitative description and descriptive statistics have been used to analyse the subsequent data.
The results show that Supply Unavailable, Supply Price Increase, and Unpredictable Lead Times are three main sources of supply risks perceived by respondents. For risk identification and assessment, specific techniques have been adopted widely, especially Communication with Suppliers. For risk mitigation, Alternative Suppliers when Supply Interrupted is perceived as the most important technique to reduce the impact of risk occurrence, while Close Working Relationship with Suppliers and Localised Sourcing are broadly used as the techniques to reduce the likelihood of risk occurrence. However, traditional buffer-oriented techniques, such as Multiple Sourcing, and Increased Stockpiling and Buffer Inventory, are not as popular in this industry as would be expected from published literature.

This study aims to analyze the willingness to engage in green supply chain management (GSCM) in Vietnam’s mining industry (VMI) as the way to improve the environmental protection. The hypothesis was proposed to find the factor effect in GSCM includes: internal environment management, external environment with two sub factor (corporate with supplier and customer) and environmental regulation. Results show that there are positive relationship between the internal environment management and green supply chain management. Results also indicate that external environmental factor can predict the green supply chain management practice and there is the correlation between environmental regulation and green supply chain management practice. ANOVA result show that statistically significant differences, i.e., p < .0.05, exist among the three enterprise sectors in the implementation of one GSCM practices, namely JVEs. There are several factors that explain why the company is leaning towards green supply chain management.

A qualitative research paradigm methodology was used. Theoretical assumptions were utilized. References by other researchers in the green supply chain and mining supply chain were also used to broaden the knowledge horizons for the study. A total number of twelve supply chain and environmental professionals from the key role players in the South African manganese and phosphate mining industries were interviewed and provided valuable input to the study. The study determined lack of information sharing between the role players in the supply chain that lead to the discovery of themes and sub–themes. The study identified seven main themes and eleven sub-themes as challenges in the implementation of green supply chain. Recommendations to address the challenges areoutlined and include the introduction of cleaner production practices by using cleaner technologies, inclusion of environmental aspects in the sourcing strategy, among others. The achievement of all these will ensure sustainable development. Originating from the study are research recommendations for the South African manganese and phosphate mining industries. The recommendations include further research to establish a green supply chain model as well as perception and expectations of policy makers in the industries.

This dissertation project was carried out under the scope of the Integrated Master in Industrial Engineering and Management within the industry environment of Sonae Arauco. It aims to redesign processes to drive service excellence by developing a new decision support system that correctly evaluates the reasons for failures in the customer service level. Following the proactive data mining methodology, in specific, the exploratory data analysis, and taking advantage of the current data provided by the ERP system in use, it is studied and designed a new data-driven process to provide accurate delay reasons. This process improvement project followed the innovative Stage-Gate methodology to create understanding, cooperation, and integration in a multidisciplinary environment. The proposed solution included short-term and longterm strategies. The short-term strategy was implemented and presented promising results across the different manufacturing units. It is constituted by the new framework, refined processes and a decision support system capable of creating accountability and standardisation for all the Logistics Managers and their plants’. There was a decrease in the area of unknowing related to delay reason, around 35%; an increase in the variety of the precise delay reasons, around 50%; and the automatic process is now capable of assign almost 70% of sales order items. The long-term strategies present theoretical results based on simulations and define the path for future improvement initiatives. More than the managerial relevance of this research project, it is intended to contribute to the literature related to the Stage-Gate methodology and its usage in process improvement projects. This innovative methodology decreases the time of the project and creates a symbiotic relationship in a multidisciplinary team environment while eliminating the functional silos. It was considered a success within the company and it is now in use on other projects.
O crescimento das cadeias de abastecimento e das redes de manufatura aumenta a exposição ao risco de disrupções e distúrbios nas operações das empresas. Estas têm de desenvolver estratégias de gestão do risco da cadeia de abastecimento, operações mais robustas e resilientes e refinar os seus processos para permitirem uma resposta mais ágil para cumprirem os prazos acordados com os clientes. Esta dissertação foi desenvolvida no ãmbito do Mestrado Integrado em Engenharia e Gestão Industrial, em ambiente industrial, na Sonae Arauco. O objetivo é redesenhar processos para proporcionar excelência no serviço através do desnevolvimento de um novo sistema de apoio à decisão que avalie corretamente as razões de falha no serviço ao cliente. Foi seguida a metodologia proactive data mining, em específico, a análise exploratória de dados e tirando partido de todos dados obtidos através do sistema ERP, foi estudado e desenhado um novo sistema para garantir razões de atraso mais precisas. O projeto de melhoria de processos baseou-se na metodologia Stage-Gate para criar cooperação e integração num ambiente multidisciplinar. A solução proposta foi composta por estratégias de curto-prazo e de longoprazo. A estratégia de curto-prazo foi implementada e apresentada resultados promisores nas diferentes fábricas. É constituída por um novo framework, processos refinados e um sistema dde suporte à decisão que garante mais responsabilidade e standardisação entre os diferentes gestores logísticos e respetivas fábricas. Resultou num decréscimo da área desconhecida em 35%; um aumento da variedade das razões de atraso mais precisas, em 50%; e um processo automático que é agora capaz de identificar cerca de 70% das linhas de encomenda. As razões de longo-prazo apresentam resultados teóricos baseados em simulações e definem um caminho para iniciativas futuras. Mais do que a relevância para a gestão, o objetivo foi também contribuir para a literatura através da metodologia Stage-Gate aplicada a projetos de melhoria de processos. Esta metodologia inovadora diminui o tempo do projeto e permite a criação de uma relação simbiótica numa equipa multidisciplinar, enquanto elimina silos funcionais. Foi considerada um sucesso na empresa e está agora em uso noutros projetos.
