  3. A Decision-Making Framework for the Optimal Selection of Suppliers
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0100059
    As supply chains continue to globalize, the need for robust supplier qualification and supplier selection and evaluation programs becomes increasingly critical. In this context, this paper aims to present a methodological approach for the optimization of the procurement processes in today’s globalized supply chains. More specifically, we first provide a categorization of the relevant past research efforts, and then propose a generic methodological framework for the supplier selection and supplier evaluation problem. This framework is constituted by a five phased conceptual decision-making methodology that outlines the whole life cycle of the supplier selection and evaluation processes. In addition, we provide a new analytical goal-programming model for the initial selection and the periodic re-evaluation of suppliers in today’s globalized environment. This mathematical programming model is based on newly developed and integrated real world supplier quality indices.

  4. Base-Stock Policies for Two and Three Stages Serial Inventory Systems with Stochastic Demand and Replenishments
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0100060
    In this paper the impact of pure base-stock replenishment policies on performance of multi-echelon supply chain networks is being examined. Specifically, we try to evaluate cycle inventory, service level, fill rate, work in process, given the replenishment policy. Serial supply chain systems are being studied; such inventory systems receive inventories from only one source and send inventories only to one receiver. The demand and the replenishment process are stochastic. The replenishment processes follow the Erlang distribution. The external demand is distributed by pure Poisson process which means that the amount that each customer asks is one unit. The supply network is modeled as continuous Markov processes with discrete states. The structures of the transition matrices of those systems are explored and computational algorithms are developed to generate them for different values of systems parameters. Mat lab software is used for any computation.

  5. Examination of the Interrelation Among the Price of the Fuel, the Cost of Transport Freight and the Profit Margin
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0100061
    The investigation of the variation of the prices of fuel and their interrelation with the cost of hauling freight and how this effects profit margins for various freight transports (ie. carriers), is of great interest for all players in the supply chain (suppliers, manufacturers and carriers). Although supply chains may vary from country to country, the end result will help establish trends that can be used to further identify links between various markets both domestically and internationally. This paper aims to examine the interrelation of the daily price of fuel, the cost of hauling freight from various US geographic locations and the profit margin that various freight haulers may have thereof. Data for the three aforementioned variables will be analyzed over a period of 4 years. The conclusions of this work can be helpful in the cost accounting of provided logistic services from a company concerning the prices of oil, aiming to help the company check the costs and the margin of profit. The conclusion of this work will help various players in the supply chain determine how the chosen variables affect net profit.

  6. Optimization of Recyclables Collection Processes
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0100062
    In the last decade environmental concerns, legislative measures and growing public awareness about the environmental consequences of waste disposal and extraction of natural resources have led to an increase in recycling and reuse efforts. However, both recycling and reuse require appropriate reverse logistics network structure, as well as adequate realization of logistics processes in such a network. The focus of this paper is to consider the problem of waste materials collection processes, which comprises pick-up recyclables from collection points and transferring them to a recycling facility. Because the recyclables value is relatively low, realization of reverse logistics processes, particularly those related to its collection, introduces the relatively high costs. On the other side, efficient and cost effective recycling in treatment facilities requires adequate supply with collected recyclables. Therefore, having in mind experience from forward supply chain management, and potentials of joint coordination of transportation and inventory decisions, this research introduces planning methodology to optimization of recyclable collection processes. That is, our intention is to propose modeling approach that simultaneously considers collection vehicles scheduling, and recyclables inventories optimization. Furthermore, as some of recyclables could be hazardous materials, risk minimizing criterion has been also considered.

  7. Trade Facilitation and Supply Chain Network Design
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0100063
    World trade has expanded rapidly over the past decades. Low production costs in developing countries, along with cost efficient logistics networks have led to the allocation of manufacturing plants in offshore industrial sites. However, lengthy customs’ clearance and service time delays and thus lengthy and highly variable lead times can undermine the efficiency of offshoring within global supply chain networks. Nearshoring, namely the practice of allocating manufacturing capacity next to the demand points, is a corporate response to such concerns. The purpose of this paper is to provide a quantitative strategic decision support methodology that captures the impact of the variability of order lead time demand on supply chain network design while further identifying: (i) the optimal mixture of nearshore/offshore production allocation capacity and (ii) the radius in the hinterland within which a global company can penetrate markets according to the entry point’s customs efficiency. Various "what-if" analyses are conducted in order to explore the sensitivity of the production allocation mixture and the trade-off between travel distance and customs efficiency. The usage of the proposed methodology is demonstrated through its application on an appropriately simplified problem instance, while obtained managerial insights are discussed.

  8. Environmental Sustainability through Clothing Recycling
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0100064
    This paper examines the process of achieving environmental sustainability through recycling of textile wastes. The recycling of textile waste can serve as a mean of providing solutions to many financial and environmental problems such as high cost of waste disposal and diminution of natural resources. The benefits and problems of this exercise are also highlighted. There are benefits to all three aspects that define sustainability: economical, social and environmental but there are also negative aspects too. The conclusion drawn is that the recycling of waste is of huge benefits especially in solving the numerous environmental problems and boosting the nation’s economy. To quantify potential ecological benefits and economical effects of textiles waste recycling, the paper proposes modeling framework which makes trade off between costs of reverse network for textiles waste establishing and operating, and its effects on the virgin materials consumption, land use reduction, employment increase, and resold wearable textiles earnings.

  9. Costing Logistics Services
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0100065
    Third Party Logistics (3PL) providers’ paradigm has grown into a critical and common strategic approach, due to the benefits of the outsourcing model. Over the past two decades, 3PL’s sector has played a critical role in the Greek economy. Logistics providers have extended their scope beyond traditional transportation and warehousing activities to also include many other main logistics services such as procurement, distribution, inventory management, packaging, and order processing services. In the services-oriented business sector (in general) the realization of the true costs of the provided services is a critical success factor. Specifically, a 3PL company by assessing the costs of services can confidently pursue the logistics objective of providing desired customer service at the least total cost. This paper presents and evaluates the costing systems that the 3PL’s companies have used. It is based on a survey that is focused on logistics providers in Northern Greece. This survey aimed at first to identify the adopted costing system, to assess its significance for both the provision of services and the designing - redesigning of services’ portfolio, to estimate the degree of satisfaction by top managers, and to recognize the problems regarding the existing costing system such as the non-value added logistics services.

    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0100066
    After years lagging behind Scandinavian and other European Cities, in 2007, the city of London took the courageous initiative to transform itself from a follower to a leader and advocate of Green Public Procurement. In this paper, now that enough data is available, we present how the 2007-2010 Green Public e-procurement project was structured; the goals, accountabilities, results of the procurement portfolio-analysis, the significance of business transformation with e-procurement, the local performance Indicators which were used and the initial spend results of the project. Looking forward, reference is made to planed actions since 2009, regarding the future implementation of European Green Procurement directives and best practices from the supply-chain domain. Today, Green Procurement is the central core of the new centrally managed public e-procurement strategy of the city of London which promises to yield significant cost savings and improved efficiencies in the 2010-2013 timeframe.

  11. Simulating the Effects of Risk Occurrences on a Hazardous Material Transportation Model
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0100067
    The present paper explores the effects of different risk incidents on a Transportation Model developed for HazMat (Hazardous Materials) shipments. The particular objective of this study is to elucidate the effects of occurrence probabilities of the different risk events on the transportation model featuring total transportation cost. First, the present research study addresses the problem of identifying and evaluating various risk factors that influence the HazMat transportation network. Next, a modeling framework for HazMat transportation is proposed as a special case of the traditional transportation network in the presence of risk-informed safety constraints that need to be satisfied. A comprehensive characterization of the underlying risk profile that is probabilistically realized through appropriately conducted Monte Carlo simulations that capture the effect of underlying irreducible uncertainties associated with the main risk-drivers is followed by the proposed solution approach to the corresponding minimum cost flow network problem while reducing risks at the desired levels. In order to examine the impact of the occurrence possibilities of different risk events on the transportation model, appropriate parameterized simulation work is carried out, resulting in identifying release probability zones and safe network configurations that correspond to certain low-risk levels and degrees of risk-related uncertainties. These simulation studies help making informed decisions on optimal transportation configurations for ensuring safety in hazardous material shipments. Finally, the presented methodological framework demonstrates its potential usefulness in making risk-informed decisions while transporting goods and classes of materials that can be potentially proven dangerous to public health and ecosystem functions.

  12. The Impact of 360o Supply Chain Integration on Operational and Business Performance
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0100068
    Supply chain integration has been a topic of significant academic interest in the operational research discipline for the last few decades. Several scientists have conducted surveys investigating its relationship with operational and / or business performance. The present paper aims to explore supply chain integration on a 360 degree radius, thus, suggesting a Conceptual Framework that accounts for all aspects that have been neglected by most researchers. The introduction of the terminology “3600 supply chain integration” is being attempted on the basis of a literature review that accumulated measures and concepts used in the past into a holistic Conceptual Framework that aims to provide a guideline towards integrating the supply chain processes of a company. The examination of the proposed Conceptual Framework was made with the use of a structure questionnaire. The questionnaire was distributed to a group of Greek manufacturing companies. The empirical data were analyzed using the “Structural Equation Modelling” technique. Results offer both theoretical and empirical evidence.

  14. Partner Selection in Supplier-Buyer Relationship with Integration of Leadtime Decisions under Demand Uncertainty Situation
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm090052
    We developed a procurement decision model, which takes into account partner selection and optimal order quantity with the integration of a planned production leadtime operational decision. Leadtime is taken into account in time and cost performance to achieve on-time delivery of a supply chain (SC) system. We contrast the three following original equipment manufacturer (OEM) conditions, (1) longer leadtime to the buyer but at a lower cost for the supplier, so the buyer has to add crashing cost to reduce the leadtime; (2) less leadtime to the buyer but at a higher cost for the supplier; (3) shorter leadtime to the buyer by adding crashing cost to reduce the inventory cost. Taking into consideration the impact of demand uncertainty directly to the buyers, we focus on simultaneous procedures in achieving an optimal solution. Our model considers an objective function consisting of operational costs and lead time decision under integrated supply chain entities (suppliers, sub-assembly manufacturers (OEMs), and buyers). Based on our numerical results, by trading-off inventory cost and leadtime crashing cost, the best possible combinations of partners in fulfilling demand from the market are B1-A2-S2 and B2-A1-S3. We found that these two combinations give $141,102.95 total profit per year to the SC system. We proposed appropriate strategies that could be applied at OEM by considering order arrival timing and leadtime.

  15. Lean Manufacturing Implementation in Malaysian Automotive Industry: An Exploratory Study
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm090053
    This paper presents an exploratory study of lean manufacturing implementation in Malaysian automotive industries. A questionnaire survey is used to explore the extent of lean manufacturing implementation. This paper also examines the drivers and barriers that influence the implementation of lean manufacturing. The survey was performed on sixty Malaysian automotive components manufacturing firms. The respondents were chosen from those who are directly involved with lean manufacturing practices such as production and quality personnel. The findings show that most of the respondent firms are classified as in-transition towards lean manufacturing practice. These in-transition firms have moderate mean values for each of the five lean manufacturing practice categories. It is also found that these firms spend more attentions and resources in internal areas such as firms’ operation and management, compared to external relationships with suppliers and customers. These firms believe that the factors that urged the implementation of lean manufacturing are the desire to focus on customers and to achieve the organisation’s continuous improvement. The results from this survey also revealed the main barriers that prevent or delay the lean implementation. The main barriers to implement lean manufacturing system are the lack of understanding lean concepts and shop floor employees’ attitude.

  17. Changing Myopic View on Outsourcing Decision in the Manufacturing Industry: A Case from Malaysia
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm090055
    The purpose of this study is to understand the factors influencing outsourcing decision in the manufacturing industry. Existing literature reveals that manufacturing industry face with challenges in the competitive environment with expectation to produce products at the lowest cost possible yet meet customer specification without affecting the quality and delivery schedules. Thus, outsourcing has become one of the alternative opportunities among the manufacturing firms. The theoretical framework is developed to understand four components namely operating cost, new product development, internal resources and technology, and as well as management competency as the determinants of outsourcing decision. This is a quantitative research and survey instrument was used. The questionnaire was distributed to 150 firms in Northern region of Malaysia with a response rate of 45%. The data was analyzed using regression to test the hypotheses. The findings showed that capital investment, latest technology and high efficiency becomes the key determinants for outsourcing decision among the manufacturing firms. It poses some implications for managers and policy makers.

  18. Virtual Network for Diamond Supply Chain in Thailand
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm090056
    Gems and Jewelry industry is one of the growing industries in Thailand. Not less than 17.7% of the exporting value from this industry is from diamond. Approximately 70% of total exporting diamonds are polished diamond. With the reputation of “Bangkok Cut”, the exporting rate seems to grow rapidly. However while we enjoy the export growth of these gems, the value add to diamond jewelry is still low. An attempt is made in this study to investigate the whole supply chain from rough cut diamond to polished diamond and to diamond jewelry. The diamond supply chain is modeled by SCOR model. Problems in the chain are reflected. It is found that Thailand has a potential to become the diamond exchange centre of the region. Surprisingly, the idea of value chain for gems to jewelry cannot be achieved. Instead, we test the solution of Virtual supply chain via E-marketplace. The architecture of this virtual exchange network is proposed. The strategy enforcing this network is then positioned.

    We developed a procurement decision model, which takes into account partner selection and optimal order quantity with the integration of a planned production leadtime operational decision. Leadtime is taken into account in time and cost performance to achieve on-time delivery of a supply chain (SC) system. We contrast the three following original equipment manufacturer (OEM) conditions, (1) longer leadtime to the buyer but at a lower cost for the supplier, so the buyer has to add crashing cost to reduce the leadtime; (2) less leadtime to the buyer but at a higher cost for the supplier; (3) shorter leadtime to the buyer by adding crashing cost to reduce the inventory cost. Taking into consideration the impact of demand uncertainty directly to the buyers, we focus on simultaneous procedures in achieving an optimal solution. Our model considers an objective function consisting of operational costs and lead time decision under integrated supply chain entities (suppliers, sub-assembly manufacturers (OEMs), and buyers). Based on our numerical results, by trading-off inventory cost and leadtime crashing cost, the best possible combinations of partners in fulfilling demand from the market are B1-A2-S2 and B2-A1-S3. We found that these two combinations give $141,102.95 total profit per year to the SC system. We proposed appropriate strategies that could be applied at OEM by considering order arrival timing and leadtime.

    This paper presents an exploratory study of lean manufacturing implementation in Malaysian automotive industries. A questionnaire survey is used to explore the extent of lean manufacturing implementation. This paper also examines the drivers and barriers that influence the implementation of lean manufacturing. The survey was performed on sixty Malaysian automotive components manufacturing firms. The respondents were chosen from those who are directly involved with lean manufacturing practices such as production and quality personnel. The findings show that most of the respondent firms are classified as in-transition towards lean manufacturing practice. These in-transition firms have moderate mean values for each of the five lean manufacturing practice categories. It is also found that these firms spend more attentions and resources in internal areas such as firms’ operation and management, compared to external relationships with suppliers and customers. These firms believe that the factors that urged the implementation of lean manufacturing are the desire to focus on customers and to achieve the organisation’s continuous improvement. The results from this survey also revealed the main barriers that prevent or delay the lean implementation. The main barriers to implement lean manufacturing system are the lack of understanding lean concepts and shop floor employees’ attitude.

    The aim of this article is to enhance the understanding about case studies as one of the research methods used in qualitative research especially in the research field of supply management. By using an example case study this article illustrates how a case study can be conducted successfully and how the validity and reliability of the research should be evaluated. The study shows that a case study as a research method is suitable for the research of supply chain management and purchasing and supply management. Because case study enables the collection of rich and profound data, an in-depth analysis of the phenomenon in question can be reached which can be highly critical for example in the development of supply relationships. The article has practical relevance especially for academic researchers in the fields of supply chain management, logistics, supply management and operations management by offering initial insights into the importance of the research process in case studies. Case studies have been criticized for the lack of rigor and thus it is important to highlight the significance of the accuracy and systematic way of action in the case research.

    The purpose of this study is to understand the factors influencing outsourcing decision in the manufacturing industry. Existing literature reveals that manufacturing industry face with challenges in the competitive environment with expectation to produce products at the lowest cost possible yet meet customer specification without affecting the quality and delivery schedules. Thus, outsourcing has become one of the alternative opportunities among the manufacturing firms. The theoretical framework is developed to understand four components namely operating cost, new product development, internal resources and technology, and as well as management competency as the determinants of outsourcing decision. This is a quantitative research and survey instrument was used. The questionnaire was distributed to 150 firms in Northern region of Malaysia with a response rate of 45%. The data was analyzed using regression to test the hypotheses. The findings showed that capital investment, latest technology and high efficiency becomes the key determinants for outsourcing decision among the manufacturing firms. It poses some implications for managers and policy makers.

    Gems and Jewelry industry is one of the growing industries in Thailand. Not less than 17.7% of the exporting value from this industry is from diamond. Approximately 70% of total exporting diamonds are polished diamond. With the reputation of “Bangkok Cut”, the exporting rate seems to grow rapidly. However while we enjoy the export growth of these gems, the value add to diamond jewelry is still low. An attempt is made in this study to investigate the whole supply chain from rough cut diamond to polished diamond and to diamond jewelry. The diamond supply chain is modeled by SCOR model. Problems in the chain are reflected. It is found that Thailand has a potential to become the diamond exchange centre of the region. Surprisingly, the idea of value chain for gems to jewelry cannot be achieved. Instead, we test the solution of Virtual supply chain via E-marketplace. The architecture of this virtual exchange network is proposed. The strategy enforcing this network is then positioned.
