    by Sara Karami, Faranak Pourasadollah, Soroush Avakh Darestani, Somayeh Ghasedi 
    Abstract: Supplier selection and evaluation have become one of the major decisions for managers in production and operations management sections for both industry and service environments. This research presents a new model that is gained by combination of House of Quality (HOQ) which is a part of Quality Function Development (QFD) utilizing Analytical Network Process (ANP) to select the appropriate supplier. This study begins with identification of features that purchased products should have them (WHAT`s, internal variable) to satisfy companies requirements, then create criteria to evaluate suppliers (HOW) to rank suppliers based on merit index to determine relative importance of factors in QFD used ANP.

  • Motivations and Barriers to the Adoption of Green Supply Chain Practices among 3PLs   Order a copy of this article
    by Sara Perotti, Guido Micheli, Enrico Cagno 
    Abstract: Over the last decade, logistics companies have experienced significant pressures towards the adoption of green practices. Meanwhile, the research community has started to show an increasing interest in the Green Supply Chain Management (GSCM) area. However, so far only a limited number of studies have focussed specifically on logistics activities and Third Party Logistics Providers (3PLs), and their motivations and barriers to the adoption of Green Supply Chain Practices (GSCP). This paper seeks to fill this gap by illustrating the results of a multiple-case study research with data collected through face-to-face semi-structured interviews with senior representatives from fifteen 3PLs. The study revealed that the adoption of GSCP does not seem to be driven by competitive advantage solely based on sustainability. However, companies have started perceiving the need to become somehow green. As for the barriers, high investments and difficulties in identifying and measuring costs/benefits appeared among the most relevant factors.

  • Joint Replenishment Problem for Multi -Echelon System with Planned Shortage   Order a copy of this article
    by Bassem Roushdy, Nahed Sobhy, Ahmed Mahmoud, Abdelrhim Abelhamid 
    Abstract: An inventory system with one warehouse and one retailer is proposed, planned shortage inventory amounts are allowed at both the retailer and the warehouse. During the ordering process, a major order cost for the lot is incurred at each location and a minor order cost is added for each item in the lot. Demand occurs only at the retailer with a constant deterministic rate. Two policies are considered for this problem; first, the centralized non-cooperative policy where a centralized decision making process is done on warehouse and retailer together to optimize their costs; second, the centralized cooperative policy wherein addition to the centralized decision process, the items at the retailer and the warehouse are replenished jointly to gain the advantage of reducing the major order cost. In the first policy, the objectives here are to evaluate the optimum order interval for each item (i), while in the second policy the objectives are to determine the common order interval, the associated multiple integers and that determines the time of order for each item, and the optimum inventory planned shortage amounts, for each item at each location, which minimize the total inventory cost for the echelon system.

  • An Exploratory Study of Supply Chain Risk Management in the New Zealand Fast Food Industry   Order a copy of this article
    by Yiran Cui, Chuda Basnet 
    Abstract: This paper reports on exploratory qualitative research into the current practice of supply chain risk management in the New Zealand fast food industry. The study found that the New Zealand fast food industry depends heavily on import from other countries and overseas suppliers for the large amount of raw materials required by the industry. These suppliers hold dominant power in New Zealand fast food industry. As a result, fast-food restaurants have limited room for switching to contingency suppliers in disruptive situations, such as natural disasters or earthquakes. Furthermore, the study also shows that the fast food industry has increased vulnerability due to the stringent food safety and health standards and customers increasing awareness of food safety issues.

  • Investigating the Impact of Access-Timing-Sizing Regulations on Urban Logistics   Order a copy of this article
    by Anjali Awasthi, Fozlul Bhuiyan, Chun Wang 
    Abstract: Freight regulations (e.g.vehicle timing, sizing and access restrictions) play a vital role in controlling congestion and developing effective urban logistics systems. Their importance is becoming even more relevant in modern times due to enormous growth in number of freight vehicle movements in urban areas. In this paper, we target the problem of assessing the impact of access-timing-sizing regulations on goods movement in urban areas. A three step approach is proposed. The first step involves conducting urban network traffic simulation to generate scenario data for the freight restriction policies. VISSIM, a microscopic traffic simulation software is used to perform this step. In the second step, we apply Design of Experiments (DOE) to analyze the simulated traffic data for testing the effectiveness of the access-timing-sizing policies. In the third step, an optimization approach using desirability function is performed to determine the exact level of regulatory policies for the city. An application of the proposed approach for City of Montreal is provided. The strength of the proposed approach is its strong practical applicability. It is also one of the few quantitative approaches available in current literature for assessing the impact of freight regulatory policies in urban areas.

  • Reliable Forward-Reverse Logistics Network Design under Partial and Complete Facility Disruptions   Order a copy of this article
    by Seyed Moreza Hatefi, Fariborz Jolai 
    Abstract: Although disruption risks may occur with a low probability in a supply chain network, they have negative financial impacts and also the recovery process from their destructive effects is very slow. This paper proposes a reliability model for an integrated forward-reverse logistics network design, which can cope with both partial and complete facility disruptions. The reliability model is formulated as a stochastic robust programing whose objective function is to minimize the fixed opening costs of facilities and the expected cost of disruption scenarios, including processing costs, transportation costs, and penalty costs for non-satisfied demands. For doing so, a recent robust optimization approach is modified to protect the concerned network against partial and complete capacity disruptions. Furthermore, a stochastic programing is employed to account for all interested scenarios. Three numerical experiments are designed to study the effect of capacity disruptions on the concerned logistic network. Finally, the results of the proposed model are compared with the conventional robust optimization models.

  • Developing a new model for Dynamic Vendor Managed Inventory (DVMI) with Considering Time Value of Money   Order a copy of this article
    by Behrooz Pourghannnad, Abolfazl Kazemi, Narges Shahraki, Payam Chiniforooshan, Mahdi Azizmohammadi 
    Abstract: This paper investigates a new dynamic two-echelon single-vendor multiple-buyer supply chain model under vendor managed inventory assumptions, which named Dynamic Vendor Managed Inventory, named DVMI, model. The DVMI model is formulated in order to find out the optimal sales quantity for each buyer at each period by maximizing the profit of supply chain. All parameters are considered deterministic and delays in the payments are permissible. In addition, the relationship between sales quantity and sales price is assumed to be linearly. Implementation of proposed DVMI model is analyzed with a case study that carried out at an Iranian dairy products company. The DVMI model is solved by using both LINGO and MATLAB Genetic Algorithm and Direct Search Toolbox. Furthermore, sensitivity of model respect to the number of selected buyers in each period parameter is analyzed.

  • MULTIPLE CRITERIA SUPPLIER SELECTION:A FUZZY APPROACH   Order a copy of this article
    by Md. Mahmudul Hasan, Md. Abu Sayeed Shohag, Abdullahil Azeem, Sanjoy Paul 
    Abstract: A company must purchase a lot of diverse components and raw materials from different upstream suppliers to manufacture or assemble its products. However, it is not only a very complicated and perplexing task to select outstanding suppliers for decision makers of strategic purchasing, but also it involves uncertainty while considering single criteria. For this reason, the decision makers of strategic purchasing greatly require an efficient, valid and fair tool to assist them in selecting appropriate suppliers forthwith. This paper proposes a supplier selection model for any kind of company by using MATLAB Fuzzy Logic Toolbox to help the purchasing department in selecting the most appropriate supplier. The main task in the proposed model involves determining the numerical score for different suppliers considering their respective performance in various qualitative and quantitative evaluation criteria and then selecting the best supplier having highest score. Fuzzy control is used to determine the best supplier by calculating the score in selected evaluation criteria which are provided in numerical values for the convenience of calculation.

  • A systematic approach to evaluate supply chain management environment index using graph theoretic approach   Order a copy of this article
    by Tarun Gupta, Vikram Singh 
    Abstract: The performance of a supply chain is characterized by its ability to remain market-sensitive without losing the integration through the chain. One of the difficulties in designing and analyzing a supply chain is that its processes are governed by the strategic factors of the supply chain. With the emergence of a business era that embraces change as one of its major characteristics, increasing the market share and survival are becoming more and more difficult to ensure. The emphasis is on adaptability to changes in the business environment and on addressing market and customer needs proactively. This paper is identifying the supply chain management from the perspective of digraph approach. An attempt has been made to identify through literature review of 150 papers contain 65 factors and understanding the interrelationship among these factors, sub factors to design a mathematical model using graph theory approach. This paper attempts to consider factors & sub factors from a system point of view.

  • Relationships between supply chain capabilities, competitive advantage and business performance: An exploratory study of the food industry in Thailand   Order a copy of this article
    by Navee Chiadamrong, Pithachaya Sophonsaritsook 
    Abstract: Thailand is one of the largest producers and exporters of agricultural and food products, and the food industry is also an important major section for Thailands economy. While the food industry can generate a high income for the country, its supply chain still contains some problems among different parties. There are a lot of factors that could affect the performance of the food industrys chain. It is difficult to choose one success factor to be improved since improving one factor could lead to a positive or even a negative impact on another factor. The purpose of this study is to explore the degree of relationships between supply chain capabilities and competitive advantages towards business performance. The data were drawn from 236 food manufacturing companies in Thailand and the measurement scales were tested and validated using Structural Equation Modeling (SEM).The findings provide appropriate supply chain strategies for successful linkage implementation so that management will be able to pursue better supply chain strategic applications directly in their business environment. The proposed model will also provide the causaleffect determinants affecting supply chain performance, to enhance supply chain strategies to meet supply chain goals, and to guide decision makers with pertinent information to implement such strategies.

  • Integration of Design for Reverse Logistics and Harvesting of Information: A Research Agenda   Order a copy of this article
    by M. Reza Hosseini, Nicholas Chileshe, Raufdeen Rameezdeen, Steffen Lehmann 
    Abstract: The literature is replete with treatises advocating the immense benefits of reverse logistics (RL) systems for organisations in terms of alleviating environmental concerns and enhancing the level of productivity. Nevertheless, implementing RL in organisations is fraught with complications with its success largely riding on fulfilling the requirements prescribed by the critical success factors (CSFs) of RL. Despite the voluminous body of knowledge on RL in the extant literature, operational aspects of RL have overshadowed some central strategic prerequisites for the success of RL systems. Drawing upon an integrative literature review, this paper provides an insight into different aspects of the implementation of RL practices. The central role of the integration of design for reverse logistics (DfRL) and harvesting of information (HoI) in the effective implementation of RL systems is then established and clarified through developing a conceptual framework. The paper concludes by putting forward an agenda for research.

  • Service Spare Parts versus Production Parts: A Centralized or Decentralized Warehouse?   Order a copy of this article
    by Maurizio Faccio 
    Abstract: The management of service spare parts has been a challenging problem for decades. Considering the case in which components are used for both production and spare parts, there are two basic strategies in inventory management: Warehouse centralization, in which production parts and spare parts are stored together in the same warehouse; Warehouse decentralization, in which production parts and spare parts are stored in two different warehouses. Each of these two strategies presents benefits and drawbacks. In the real industrial environment it is possible to find both these strategies. On the other hand, the definition of the warehouse centralization/decentralization strategy seems to be related more to following some rules of thumb than to following a structured decision-making process. The aim of this paper is first to define a set of influencing factors driving the decision. Secondly, starting from wide experimental data derived from Italian companies, it provides a rapid and easy heuristic procedure for practitioners based on a decision tree approach to the correct definition of the service spare parts warehouse centralization/decentralization strategy.

  • Lean practices in machinery manufacturing industries- A case study   Order a copy of this article
    by P.G.Saleeshya , Sneha A, Karthikeyan C, Sreenu C, Rohith A.K 
    Abstract: Lean manufacturing is an emerging concept in the Indian manufacturing scenario. Many small and medium scale enterprises in the country are aiming at becoming lean and thereby improving their productivity. This paper is an outcome of a case study in one such enterprise that deals with the manufacture and assembly of offset printing machinery in India. Being a vendor based organization, part shortage due to delays in the process was a major problem faced. A thorough analysis of the various vendors and processes that the product goes through was done and the process flow was mapped to obtain a clear picture of the entire system, and software modeling helped arrive at quantitative results. Lean tools like Pareto analysis, 5-Why analysis, source inspection etc. were used to identify and eliminate the various factors that led to delay. Proper scheduling of jobs is also essential to reduce waiting time, and therefore an algorithm has been developed to help arrive at an optimum scheduling sequence. The results from this case study have proved successful in reducing the lead time of the component under study.rnrn

  • ANALYSIS AND MEASUREMENT OF SUPPLY CHAIN FLEXIBILITY   Order a copy of this article
    by Georgy Kurien, M Qureshi 
    Abstract: Supply Chain flexibility is a strategic and tactical necessity for sustenance and progress of business enterprises. Measurement of flexibility is therefore necessary for its monitoring, control and communication. The study proposes a framework and a methodology for flexibility performance measurement of supply chains. The framework identifies flexibility objectives and its contributing attributes at four levels of the supply chain and suggests taxonomy of flexibility performance measures. A methodology to prioritize the contribution of each performance attribute to achieve the desired flexibility objective using Analytic Hierarchy Process (AHP) has also been proposed and demonstrated in this study. The research is based on detailed literature based study and analysis of existing frameworks of flexibility performance measurement in supply chain and expert opinion. The proposed framework is suitable for measurement, monitoring and controlling flexibility in a supply chain in addition to prioritising contributing attributes of flexibility. The research does not test the model but suggests a platform for further development.

  • Supply Chains subject to Demand Shocks   Order a copy of this article
    by Kannan Nilakantan 
    Abstract: This paper takes up the study of the behavior of a distribution warehouse of a supply chain when it is subjected to sudden demand shocks. The warehouse is at the downstream end of the supply chain, and caters to the demand off-take of the chain which follows a responsiveness strategy. We study the effect of different types of replenishment policies followed at the warehouse, and compare their performance with one another in the warehouse system, looking at how quickly they can absorb the shock and smooth out the system, and restore it to normalcy. We find that all the conventional replenishment policies suffer from the disadvantage that they inevitably transmit the shock backwards in the chain to the upstream units. We subsequently propose a different design paradigm to formulate the problem under, which prevents the backward transmission of the demand shock to the upstream units, but rather attempts to smooth it out. rnrn

  • The Effect of Attributes of Distribution Channel Member on Supply Chain Management: An Empirical Analysis of Social Networks in Business   Order a copy of this article
    by Lakshmanasamy Thangamuthu, Anil Chandrasekaran 
    Abstract: Marketing channels are an integral part of the supply chain phenomenon and play a vital role as a network. Unlike the supply side of the chain, distribution networks play more collaborative role in making available the product in the market. It is essential to understand the influence of the social and demographic attributes of the individual members in the distribution on the level of networking amongst the members and is a concern for the managers of the organisations to promote mutual relations to achieve maximum product coverage. This paper empirically analyses the effects of such micro factors in the distribution network using the social network analysis and graphs the emerging empirical network in a business related to construction industry. The results show that personal and social aspects of individuals in the network influence the linking, networking and the structure of the network which have important implications for business promotion and product delivery.

    by Rapee Pongpanich, Tzong-Ru Lee (Jiun-Shen), Nirote Sinnarong 
    Abstract: In this paper, the key success factors (KSFs) for selecting the Consumer to Consumer (C2C) logistics provider in Thailand. Relevant factors related to the selection criteria of a C2C third party logistic (3PL) provider are first solicited from the literatures and seventeen major factors which are categorized in five groups are identified by a group of experts. Then, we apply Analytical Hierarchy Process method incorporated with the three ranking logic to calculate the global weight for each factor. Finally, it is found that the top four KSFs for selecting C2C 3PL providers in Thailand are (i) transport price, (ii) on-time delivery, (iii) quality of service and (iv) short lead time. These results can let the 3PL providers understand the needs of the players in the C2C markets, Furthermore, it can be also treated as a guideline for the C2C entrepreneurs to monitor and improve the quality of their customer services.

    by Gary Moynihan, Shaoyi Wang 
    Abstract: The objective of this project was to develop a prototype Web-based decision support system for the integrated supply chain, and demonstrate how the performance of the supply chain could be improved by this system. Data from two industrial case studies were examined, and their limitations were identified. An extensive management science/ operations research model and a subequent Web-based decision support system were proposed to overcome the determined limitations and better adapt to the real world. A traditional system design methodology was employed to develop the system. Verification and validation were conducted on the system by utilizing accepted methods. The system eases data entry for users and helps to avoid a partial perspective view of the supply chain. It can also overcome an overabundance of transactional data for the purpose of managerial decision making, and the difficulties to integrate the activities of multiple organizations.

  • Perceived Barriers, Collection models, Incentives and Consumer preferences: An exploratory study for effective implementation of reverse logistics   Order a copy of this article
    by Saumya Dixit, Anurika vaish 
    Abstract: Proper disposal of e-waste by implementation of reverse logistics is a potential area of research for controlling greenhouse gas emissions, global climate change and landfills. The consumers serve as the starting point for product acquisition in reverse logistics. However, previous researches show that most of the consumers prefer storing their e-waste at home to returning it to producer and thus lowering proportions of e-waste available to producer for disposal. This research work aims to ascertain consumer preferences in order to strengthen acquisition of e-waste from them. Therefore, in order to motivate consumers to return their mobile waste, the paper present a brief review of the perceived barriers, collection models and the desired incentives from the perspective of consumers themselves, followed by the research methodology, results and ends with scope for future research.

    by Supawadee Putthinoi, Komsak Meksamoot, Pitipong Yodmongkol, Nopasit Chakpitak 
    Abstract: As Thailand enters an ageing society, reverse logistics concerning unused household items by elderly people becomes a problem for the local community. Throughout their lifetime, elderly people usually collect or hoard things in their house, which can lead to the risk of accidents by falling. There is very poor reverse logistics of household items, such as unused charity donations, in developing countries. A suburban village in Thailand was selected as a problem model. This study focused on unused household items in houses of the elderly. Therefore, it aimed to introduce the SCOR model for assessing this reverse logistics problem. The retail suppliers in the community were placed into six categories; electrical store, furniture store, pharmacy, bookstore, supermarket and temple. The flow of household products was a direct line from retailers to end users. The SCOR process (PSMDR) elements of all suppliers did not support the reverse logistics activity for elderly customers. To list in formal language was good for the local community to enable a flow of reverse logistics, which should improve Thailands ageing society.

  • Complex Network Theory Based Approach for Designing Resilient Supply Chain Networks   Order a copy of this article
    by Sonia Irshad Mari, Young Hae Lee, Muhammad Saad Memon 
    Abstract: Globalization within supply chains opens many doors for new opportunities but can also result in highly complex, unstable and fragile supply chains. The recent literature mainly covering supply chain risk management emphases a lot of attention towards making the more robust and resilient supply networks, the reason may be the increasing number of disruptions. Due to importance of complex network theories in supply chain system, this paper is written to analyse the supply chain networks on the basis of complex network topologies. The authors examine the advances of complex network theories to understand the properties of these networks in underlying efficient supply chain. In this paper, the resilience metrics for supply chain are developed based on complex network theory. Various important complex network models are compared using agent-based simulation approach with resilient supply chain network to propose the applicability of complex network models for designing a resilient supply chain. Simulation results shows that supply chain network can be designed based on complex network theory especially as a scale free network. It was also concluded that scale-free models have some limitations and cannot accurately represent an efficient and resilient supply chain. Therefore, it is suggested that a scale-free model should be developed that can represent more robust and resilient supply chain network.

  • Routing strategy in a distribution network when the driver learning effect is considered   Order a copy of this article
    by Maurizio Faccio, Alessandro Persona, Stefan Røpke, Giorgia Zanin, Battini Daria 
    Abstract: This paper faces one critical short term decision: the construction of routes for daily goods deliveries in a distribution network. It investigates the possibility of applying a fixed routing strategy instead of a daily routing optimization strategy, analysing the benefits derived from the drivers familiarity with his/her surroundings, customers habits and set-ups. The final aim is to provide an effective and flexible decision-making tool to identify the best routing strategy, considering the level of learning invested by each driver. It is assumed that learning effect impacts on the service time, i.e. on the time spent in service operations once arrived at the customers site. Results demonstrate that fixed routes strategy can often be better than the daily optimized strategy and strongly depends on the parameters investigated in this work. Two case applications are provided to help the readers comprehension and demonstrate the methodologys potential and its practical implications.

  • Truck Turnaround Time (TTT) problem at the port of Colombo and a solution through inland ports   Order a copy of this article
    by Jayantha Rathnayake 
    Abstract: This paper examines the Truck Turnaround Time (TTT) procedure at the port of Colombo where trucks are said to be delayed causing congestion in the port and on the roads of Colombo city. A survey conducted in the Colombo port premises showed that the TTT in the Colombo port is relatively longer; ranging from minimum 47 minutes to maximum eight (8) hours with Mean value of three (3) hours. As a solution to improve the TTT, applicability of inland ports, which are expected to replicate the services and facilities of seaports, was considered. Secondary data, other data presented in the studies conducted earlier on the subject matter and an opinion survey were used as the methodology to assess the plausibility of the proposed solution to TTT problem and it was found that inland port to be the most feasible and suitable solution that meets the need of most of the stake holders of the logistics industry as the inland ports could be connected to the sea port through railways thus bringing a relief to the problems created by TTT in the port and its effect on the city roads.

  • EVALUATION OF EXPECTED PAYOFF THROUGH CONTAINER INTERCHANGE BETWEEN SHIPPING LINES: A SOLUTION TO CONTAINER INVENTORY IMBALANCE IN SRI LANKA   Order a copy of this article
    by Lalith Edirisinghe, A.W. Wijeratne, Jin Zhihong 
    Abstract: This paper evaluates the expected economic benefit that could be achieved by interchanging containers between shipping lines by employing the popular Game theoretic approach. It comprehensively discusses the causes underlying the container inventory imbalance; the absence of collaboration (work alone) with respect to containers; the models of collaboration (win-win situation); and the quantitative and qualitative benefits that could be achieved through shipping alliances. The paper suggests barriers to a collaborative approach by carriers as confidentiality of information; regulatory, competition and social issues; and business philosophy of firms. The paper identifies the core areas relevant to empty maritime container inventory imbalance including external trade volumes, commodity types, logistical issues, seasonality, container types and sizes. The ultimate objective is to ascertain the appropriateness of collaboration as a solution to container inventory imbalance in Sri Lanka. Therefore attempts were made to calculate economic benefits of container interchange using specific models. Furthermore the paper looks into those aspects that make the implementation of collaboration more difficult (inhibitors) despite the existence of active agreements between shipping lines and the opportunities and facilitators.

  • Integrating X-ray Technologies with Intelligent Transportation Systems for Enhancing the International Maritime Security   Order a copy of this article
    by Hokey Min, Yong-Kon Lim, Jong-Won Park 
    Abstract: Over the past decade, the use of X-ray scanning technology for cargo inspection has been on the rise due to its effectiveness in providing clear and unobtrusive views of the contents of items hidden inside containers. Also, it is able to add intelligence and to minimize human intervention in the cargo inspection process without opening up suspected containers. Although X-ray scanning technology is proven to be useful for automatic detection of potential dangers or illicit contents (e.g., narcotics) inside containers, its usefulness may be constrained unless it can be embedded within the system-wide decision support tool. Such a tool includes an intelligent transportation system (ITS) which is designed to improve transportation safety and mobility through the seamless integration of information and communication technology, transportation infrastructure, and shipping vessels. This paper is one of the first to combine X-ray scanning technology with ITS for cargo inspection procedures and gauges its usefulness for enhancing maritime security in global supply chain operations.

  • Using fuzzy DEMATEL for evaluating supplier selection criteria in manufacturing industries   Order a copy of this article
    by Reza Kiani Mavi, Hossein Shahabi 
    Abstract: The concept of SCM has received increasing attention from academicians, consultants, and business Managers. Organizations have begun to recognize that SCM is the key in building a sustainable competitive edge for their products or services in an increasingly crowded market place. Further, more and more products reach the customer through supply chains that are composed of independent firms. In the highly competitive scenario, suppliers play a vital role in making a business organization successful. Business of any organization is continuous process and therefore the supplier selection is also dynamic in nature. Therefore, supplier identified for one period may not necessarily be same for the next period to supply the same set of parts. Hence, the supplier selection problem is highly dynamic in real practice. This paper tries to evaluate the influence of effective factors in supplier selection by using Fuzzy DEMATEL method. In this regard, three main criteria including management, logistics and organizational dimensions with 15 sub-criteria identified. 20 experts of academics and practitioner have participated in this study. Results show that planning, partnership and collaboration has the most causal effect on other criteria and cost of logistics is mostly affected by other criteria in manufacturing industry supplier selection.

  • The Shortest Route for Transportation in Supply Chain by Minimum Spanning Tree   Order a copy of this article
    by Arash Shahin, Fatemeh Jaferi 
    Abstract: The aim of this article is to propose a solution for finding the shortest route for transportation between supply and demand. For this purpose the problem of supplying car battery from Tehran to the centers of provinces of Iran has been investigated and a graph has been developed in which the center of each province is regarded as a location of this graph and the distances between the center of each province and the neighboring provinces is regarded as the length of chords. Then by using the heuristic prim algorithm, the Minimum Spanning Tree of this graph has been obtained, and this tree has shown the shortest route for transportation. The problem has also been solved by meta-heuristic genetic algorithm, and the response has been compared with prim algorithm, and it has been shown that for big problems, the genetic algorithm can be used. In order to reduce the density of freight cars in roads, a scenario has been proposed by which, roads traffic and accidents, fuel consumption and customer delivery time can be reduced. The innovation of this research is in using genetic algorithm in graphs for analyzing supply chains to find the shortest route between producer and customer in every area and also to offer new approach for increasing efficiency of transportation, reducing time and total cost.

    Abstract: In the competitive marketplace, corporate social responsibility (CSR) is becoming a pre-emptive theme for implementing with supply chain functions of an organization. This study aims to identify and analyze the CSR practices to improve or implement an effective and efficient CSR based supply chain performance system. To achieve the aim, a list of thirteen significant CSR practices was identify based on literature review and discussion with field experts taken from automobile industry located at National Capital Region (NCR) of India. As human/expert judgments contain certain degree of vagueness, fuzziness and impreciseness, the collected fuzzy input data on identified CSR practices was aggregated through Converting Fuzzy data into Crisp Scores(CFCS) defuzzification method and then analyzed using fuzzyDecision Making Trial and Evaluation Laboratory (DEMATEL) approach.The analysis discloses that the CSR practice top management and employee awareness about CSR comes out with highest prominence (4.4709) and relation (1.2993) value, hence seems as a most significant and influencing CSR practice,while CSR practice response to non-governmental organization (NGO) working on environmental and social issues comes in picture with lowest prominence (3.5104) and relation (minus 0.9206) value, thus considered as ample influencing CSR practice.This research also visualizes the categorization into cause and effect group, degree of interaction, and inter-relationship of considered CSR practice. The findings of present research work may enable mangers to build correct plan assessments and to frame polices,based on consistent importance of CSR practices, in order to improve or implement effective CSR based supply chain performance system.

  • Ordering Policy for Non-Instantaneous Deteriorating Items in Two Warehouse Environment with Shortages   Order a copy of this article
    by Chandra Jaggi, Priyanka Verma, Mamta Gupta 
    Abstract: The majority of existing literature in deteriorating items inventory systems deals with items that are subject to deterioration as soon as they land in the warehouse. However, there are items that have a shelf life and start deteriorating after a time lag (non-instantaneous deteriorating items). Under some special conditions, viz., attractive price discount, low storage cost, high demand, etc; the procurement of a large amount of such items at a time is decided. Because of the fixed capacity of the own warehouse (OW), a rented warehouse (RW) is used to store the excess quantity. Further, the last-in-first-out (LIFO) dispatching policy is the most preferred policy by the researchers in two-warehouse models, but this presumption may not be in line with real life scenario. To enhance the usefulness of merchandise or goods, businesses commonly follow the first-in first-out (FIFO) policy. This multiplicity of objectives forms the base and main motivation of our research. In the present paper, a two-warehouse inventory model for non instantaneous deteriorating items is developed under FIFO dispatch policy; shortages at OW are also allowed. The solution procedure has been illustrated with the help of a numerical example and a comprehensive sensitivity analysis, with respect to the important parameters of the model, is considered. Jaggi and Verma (2010) two-warehouse LIFO model with non-instantaneous deterioration is also compared with the proposed FIFO dispatching two-warehouse model.

  • An Adaptive Structuration Theory Approach to Price Transmission in the Rice Value Chain   Order a copy of this article
    by Togar Simatupang 
    Abstract: Most of the quantitative studies on price transmission of agricultural products deal with estimating and testing elasticity as well as detecting the presence of asymmetries in the transmission mechanism. It has been argued that the imbalance on price transmission lies in bargaining and market competition among actors. However, previous studies about the process of actors social interaction are partially addressed. The role of actors behavior and the process of social interaction that is constructed and reproduced are regarded as important parts of price transmission. Adaptive structuration theory (AST) is proposed as a research framework, based on actors, structures and agencies taking place through social interaction. The framework for price transmission is built from the extensive structuration matrix which shows the constructs of the structuration theory and their interactions. As a result, nine propositions of structuration are formulated.

  • Application of Autonomous Control in Event Logistics Concept - Implementation and First Results   Order a copy of this article
    by Florian Harjes, Bernd Scholz-Reiter 
    Abstract: The complexity and dynamics of logistic systems continuously increase due to growing customer demands, small lot sizes and numerous product variants. As a result, the established planning and control approaches reach their limits and new, innovative approaches come into focus. This paper introduces a concept based on the paradigm of autonomous control that deals with the problems related to the resource allocation under complex and dynamic circumstances, especially with regard to the circulation of rental articles in closed logistic systems. At this, the paper focuses on the application field of event management to demonstrate the shift from a centralised to a decentralised control in the corresponding logistic processes. The presented approach adapts and combines several autonomous control methods for the distribution of rental articles in event logistics, including the planning of personnel, transports and routes in closed dynamic networks. The overall objective is an autonomously controlled distribution system for rental articles in event logistics, including a process mapping, the development of an autonomously controlled target process as well as a description of the overall system architecture (modelling process + soft- and hardware architecture). The paper further includes a description of the implementation proceeding, first simulation-based performance measurements and an efficiency analysis. All aspects of the approach are clarified by means of an example company from the given field of application.

    Abstract: There is a hidden reserve for improving the efficiency of supply chains at inventory management. The aim of this research is to develop a special approach for optimization of such systems with regard to the Time Value of Money (TVM) according to the scheme of simple interest, and to modify the EOQ formula respectively. It is caused by the fact that in such models profits are not used to increase the total annual supply, and the interest rate for the calculation of the TVM should reflect the effectiveness of cash flow of supply chain itself. A new formula considering the TVM for EOQ is found. The analytical assessment of the interest rate, which characterizes the supply chain efficiency and is applied in calculations with the use of the generalized EOQ formula, is given. The developed method allows to receive additional synergy effect the increase in profitability of a working capital.

  • The economic number of operators for the machine interference problem with heterogeneous machines and preemptive priority   Order a copy of this article
    by Gregory Gurevich, Baruch Keren, Yossi Hadad 
    Abstract: This paper proposes a model for a special case of the machine interference problem, where several heterogeneous machines that produce the same product randomly request a service provided by a group of operators. Each machine (or a group of identical machines) randomly requests several different service types that are provided by groups of operators, such that each request for a service can be fulfilled by a qualified operator that is assigned to perform only this specific service. Presuming the preemptive priority in service between the heterogeneous machines, the model allows computing of the economic number of operators in the context of different objective functions via the binomial probability function. The advantages of the proposed model are that it is much easier to apply when compared to the Markovian models, and that it does not need any restrictive assumptions about failure rate and service distribution, as those of the Markovian models. To demonstrate the applicability of the model, a theoretical analysis and a real case study are presented.

    by Dharamvir Mangal, Tarun Gupta 
    Abstract: Cost effective supply chain management under various market, logistics and production uncertainties is a critical issue for companies in the current development. Reservations in the supply chain usually increase the variance of profits (or costs) to the company, increasing the likelihood of decreased profit. Demand uncertainty, in particular, is an important factor to be considered in the supply chain design and operations. To hedge against demand uncertainty, safety stock levels are commonly introduced in supply chain operations as well as in supply chain design. In this paper, authors proposed the use of deterministic planning and scheduling models which incorporate safety stock levels as a means of accommodating demand uncertainties in routine operation.

    Abstract: This paper develops a fuzzy inventory model for deteriorating items with ramp type demand function which determines the optimal replenishment policies by minimizing the total cost of the inventory system. Shortages are allowed and are partially backlogged. Fuzziness is introduced in the traditional cost components to a certain extent using the triangular fuzzy numbers and the signed distance method is used to defuzzify the total cost function. This paper, first, develops the crisp model by considering the two possible scenarios arise due to ramp type demand function, and then their corresponding fuzzy models are developed. To test the validity of the model, numerical study is also conducted followed by the sensitivity analysis on the key parameters.

    by Hossein Salehi, Reza Tavakkoli-Moghaddam, Gholam-Reza Nasiri 
    Abstract: Location-allocation problem as one of the strategic decisions in supply chain management has become the focus of research attention. In this paper we design a distribution network by modeling for location-allocation in a supply chain that involves a fixed plant, distribution centers with multiple levels of capacities and retailers. The aim is to select the optimum numbers, locations, capacities of the opening warehouses, allocation retailers to the opened warehouses, therefore all multi-product stochastic customer demands are satisfied at the minimum total cost of the distribution network and the maximum average of warehouse utilization. In addition lateral transshipment within an inventory system is considered (i.e., product movements between locations of the same echelon).The model developed as a mixed-integer nonlinear programming model and an efficient heuristic-based memetic algorithm is proposed. Furthermore, a number of test problems are solved and the associated results are compared to evaluate the performance of the proposed algorithm.

    Abstract: The objective of this paper is to determine optimal inventory levels of flu vaccines at one medical facility using the newsvendor model while also maintaining customer service levels and maximizing profit. Using four years of empirical evidence, we illustrate the optimal ordering quantity of flu vaccine by healthcare managers to provide proper medical coverage. This research provides an initial step for ordering quantities of perishable biopharmaceuticals. The research also develops a framework for the logistics of ordering in the presence of multiple constraints throughout the supply chain network. An important contribution of this work is demonstrating the value of the posited logistics model within the context of a healthcare application that has the potential to influence practice.

  • Multi-attributes based comparison of JIT Distribution process of Supply chain.   Order a copy of this article
    by Om Prakash Mishra, Vikas Kumar, Dixit Garg 
    Abstract: Distribution process of a supply chain management is very important and strategic. To stay efficient in delivering the finished goods in the hands of end user, the speed and responsiveness of distribution mechanism are most essential. Just in Time (JIT) has proved result oriented in the manufacturing systems since 1985. Since then its applicability in several fields are being investigated. Low inventory, small lot size, least lead time and quality product are some desirable features of JIT, which proves beneficiary to the firm. This paper highlights JIT applied Distribution Process in order to shorten the lead time, inventory holding costs. Application of Graph theory (GTA) methodology has been used to investigate the interdependencies of Dimensions and its attributes of JIT implemented distribution. Then an empirical value of JIT distribution process (JDP) of an organization has been derived , subsequently coefficient of distribution dissimilarity and similarity have been found for two organization and based on these values comparison of any two organization can be done. This approach can be used to know the lacks of various organizations based on their Feasibility Index of Transition (FIT) value. This value can be used to modify the existing practices in distribution process by improving the low performing dimension; consequently the whole supply chain process will improve.

  • Collaborative capacity sharing in liner shipping operations   Order a copy of this article
    by Eric Wibisono, Phongchai Jittamai 
    Abstract: This paper studies collaborative capacity sharing between two liner shipping companies by investigating the impacts of collaboration on the sharing of fuel consumption. The proposed model is extended from the vehicle routing problem with time windows (VRPTW) through the inclusion of slow-steaming decision variables and constraints to manage the sharing of fuel consumption. Two cases differing in size are developed using Indonesian archipelago for the data background and three policies on fuel-consumption sharing are investigated: open policy, proportionate-sharing policy, and equal-sharing policy. The application of the collaborative model in Indonesian archipelago contributes to the scant literature in maritime logistics collaboration. The optimisation results from generated instances show that the open policy leads to minimum total fuel consumption but the unclear pattern in fuel-consumption sharing between carriers makes it impractical for planning purposes. Moreover, the fuel consumptions of the proportionate-sharing and equal-sharing policies are not significantly different but the smaller variance in the results of the proportionate-sharing policy indicates more predictability. The proportionate-sharing policy is therefore considered the most suitable for route planning.

  • Traffic Disruptions: A Dynamic Heuristic Approach   Order a copy of this article
    by Sundaravalli Narayanaswami 
    Abstract: A heuristic solution to rescheduling railway traffic, when an already planned schedule cannot be adhered to because of disruptions is presented in this paper. A MIP (Mixed Integer problem) formulation is developed to model disruptions that lead to conflicts on a single track bi-directional scheduled traffic with over-taking and follow-up capacities. The proposed objective is to minimise the total delay of all trains in the operational domain at their respective destinations. We have developed a rescheduling heuristic that re-sequences the conflict trains using a Look-Ahead based Dynamic Ranking (LADR) approach. LADR procedure ranks the conflict trains on their static priority, myopic delay, critical ratio, number of future conflicts and total future delay. The heuristic procedure takes as input a conflict free schedule and is action-initiated by any disrupt to this schedule. The conflicting trains are identified and on the basis of their sorted LADRs departure times are assigned. Each conflicting train is rescheduled one at a time till all trains are rescheduled to their destinations. Our results are promising when evaluated against three other known procedures on a medium sized real world data.

  • Learning platform for supply chain system optimization   Order a copy of this article
    by Zdravko Zekić, Nataša Rupčić, Marijana Jakopič 
    Abstract: Fierce competition, dynamic market conditions and resource scarcity pose a constant demand on companies to redefine their business models in order to achieve competitive advantages. The paper offers a review of development trends in modern supply chain management with emphasis on strategic learning partnerships as a means for achieving supply chain competitive advantage. Organizational learning has been proposed as a technology for achieving long-term sustainability in strategic supply chain partnerships. However, in practice supply chain partnerships inadequately exploit established forms of cooperation as vehicles for learning and building knowledge repositories. This can be improved by introducing and optimizing the process of organizational learning in every partnership member as well as a joint partnership activity. The study is aimed at proposing a conceptual model of the learning platform for supply chain optimization. Potentials for its introduction have been estimated by using the case study of Agrokor, Croatian largest food concern.

  • A note on the joint economic lot size model with stochastic demand and variable lead time   Order a copy of this article
    by Reza Hosseini Rad, Jafar Razmi, Mohamad Sadegh Sangari, Zahra Fallah Ebrahimi 
    Abstract: This paper considers the problem of choosing optimal production policy in an integrated production-inventory system comprising a single manufacturer and a single buyer. Two production scenarios are compared, namely continuous and lot-for-lot production policies, using a mathematical modeling approach and the expected total joint cost is considered as the performance measure. In addition, the lost opportunity cost due to production downtime in the lot-for-lot policy, including the cost of unemployment of human resources and stoppage of the production line, is incorporated into the model. Numerical experiment and sensitivity analysis in terms of setup and lost opportunity costs are provided to illustrate the theory and the percentage of difference in the expected total cost of the two policies is analyzed. The presented approach helps managers to make the right decisions on the optimal production policy under different conditions, especially where expert and technical human resources and/or expensive production equipments are utilized.

  • Assessing the environmental impact of logistics in online and offline B2c purchasing processes in the apparel industry   Order a copy of this article
    by Riccardo Mangiaracina, Alessandro Perego, Sara Perotti, Angela Tumino 
    Abstract: This paper presents an Activity-Based model for the assessment of the environmental impact of the purchasing process in the apparel industry, comparing traditional in-store and B2c e-commerce channels with a focus on logistics activities. Interviews with company managers and secondary sources were used to develop and validate the model. A base case was selected and applied, and a sensitivity analysis was carried out. Based on the model results, the base case online purchasing process was found to be to be more sustainable than the offline one, due to the lower environmental impact of the Pre-sale and sale and the Delivery phases. The impact of logistics is generally very high in both the online and offline purchasing processes (i.e. 99% and 62% of total CO2e emissions respectively). In the online case, the location of the consumer house (i.e. inside or outside the city centre) is the parameter with the greatest environmental impact, whereas in the offline case the distance between the consumer house and the store was identified as the most significant factor. The paper addresses an identified need to quantify the environmental effects of the offline versus online purchasing channels, and logistics activities in particular. From a managerial viewpoint, the model can help practitioners understand the environmental consequences of their business and can support internal monitoring procedures.

  • Centralized and Decentralized Three Echelon Inventory Model for Optimal Inventory Decisions under Price Dependent Demand   Order a copy of this article
    by Dega Nagaraju, A Ramakrishna Rao, S Narayanan 
    Abstract: In this paper, a three echelon inventory system with a single manufacturer supplying a single product to a single distributor and then to a single retailer, is considered. Mathematical model is developed for annual total relevant costs of the coordinated and non-coordinated supply chain. The novel idea of the proposed model is that the demand is a function of retailers unit selling price, which in turn is a function of retailers replenishment quantity with dependence factor. The objective of the model is to demonstrate the optimality of inventory decisions, shipment frequencies and total relevant costs with respect to dependence factor. Numerical illustration is carried out to demonstrate the optimality of replenishment decisions. Finally, managerial insights are inferred in selecting the optimal replenishment quantity and shipment frequency that minimizes the total relevant cost of the supply chain.

  • Cost innovation in global supply chains: The case of Huawei Technologies   Order a copy of this article
    by Lars Bengtsson, Weihong Wang 
    Abstract: Cost innovation has been used to describe how firms offer a variety of customized and high-tech products at low prices. Insights into how this trade-off is overcome by supply chain design are lacking. This paper analyses the global supply chain strategies and practices of Huawei Technologies, and specifically how these contribute to cost innovation capability. The paper is based on interviews with managers at Huawei headquarters in Shenzhen, plus managers at two European supply chain centres. The case study shows that even though Huawei does not possess specifically unique supply chain solutions, there are some features that drive Huawei towards cost innovation in its supply chains. Some of them concern low-cost operations based on the location of main R&D, manufacturing and suppliers to China, in combination with a strong customer orientation, an integrated supply chain organisation and a balanced outsourcing strategy.

    by Burra Karuna Kumar, Dega Nagaraju, S Narayanan 
    Abstract: In the current global business environment, the competition is between the supply chains, but not among echelons of the chain. Hence, it is highly essential to bring down the cost of the supply chain rather than reducing the costs of individual echelons independently. This work focuses on modelling and optimization of a coordinated and non-coordinated three-echelon supply chain with the consideration of ordering/setup costs, transportation and carrying costs. The objective of the present work is to demonstrate the optimality of inventory replenishment decisions, shipment frequencies and the annual total relevant costs under linear price dependent demand. Numerical illustration is carried out to find out the optimal values of objective function and decision variables. Also, the parametric analysis is carried out to show the influence of model parameters.

  • Comparison of Single-Echelon vs. Multi-Echelon Inventory Systems Using Multi-Objective Stochastic Modeling   Order a copy of this article
    by Nadeera Ekanayake, Nilesh Joshi, Shital Thekdi 
    Abstract: Recent advancements in inventory management have identified need for investigating benefits of single-echelon and multi-echelon systems. Single-echelon inventory control problems focus on determining the appropriate level of inventory for an individual unit within the supply chain network, while multi-echelon inventory optimization takes a holistic approach by focusing on the correct levels of inventory across the entire network. This paper presents a stochastic modeling approach for multi-tier supply chains with multiple inventory items. The approach will be used to compare behavior of single-echelon vs. multi-echelon inventory systems. A multi-objective optimization method is used to optimize models behavior with two conflicting objectives: minimizing average inventory across the supply chain and maximizing overall fill rate. The results show that single-echelon systems result in higher inventory levels and lower fill rates, while multi-echelon systems result in lower inventory levels while maintaining higher fill rates for the entire supply chain network. The methods are demonstrated on a sample network database.

    Abstract: Service supply chain combines the management of information, processes, capacity, service performance and funds from the earliest supplier to the ultimate customer. This study explores the need for supply chain coordination required to deliver services for healthcare industry. Building on prior research, this study looks quantitatively at the interplay of service supply chain coordination factors (i.e. accessibility, affordability and awareness) and their influence on hospital performance. Hence, empirical research in an emerging economy such as the Kingdom of Saudi Arabia was selected to test the predictive relationship between service supply chain coordination factors and performance. The findings from this study show that from the three predictive relationships tested, performance of hospitals was challenged by the increasing lack of service awareness built in the industry.

  • Fuzzy Analysis and Evaluation of Supply Chain Performance: A Focus on Leather Products in Tanzania   Order a copy of this article
    by Erick Massami 
    Abstract: In this study, a fuzzy comprehensive model is applied to evaluate the performance of supply chain for leather products in Tanzania. The evaluation procedure starts by identifying major criteria and sub-criteria that influence the supply chain performance of leather products. These criteria and sub-criteria are used by assessors to assign values that are used to generate each single factor evaluation set; which is used to compose the single factor evaluation matrix. The relative importance of each criterion in the weight set is obtained by Fuzzy Triangular Number (FTN) method. Eventually, the weight set of influential factors (i.e. criteria) is multiplied by the single factor evaluation matrix to compose the fuzzy based comprehensive evaluation. The computational results show that the performance of the leather products supply chain (LPSC) in Tanzania is poor. Thus, the findings call for all stakeholders in the Tanzanian leather industry to take appropriate measures that would boost the supply chain performance. Moreover, the proposed model can be used to evaluate vague objectives in other industries.

    Abstract: The Purpose of this paper is performing an empirical investigation on the impact of structural capital (supplier evaluation, Supplier development, Information sharing, Network ties and Appropriability) on buyer satisfaction and the relationships between buyer satisfaction and buyer performance (cost, quality, delivery, flexibility and Innovation). The statistical population of this study is the buying managers of manufacturing companies in Qazvin province. 113 questionnaires with multiple choice questions were distributed among sample individuals. The partial least squares method and Smart-PLS software were used for analyzing the data in order to evaluate the relationship between variables and their impact on each other. Empirical results confirm that structural capital has positive impact on buyer satisfaction. Among the structural capital factors, the network ties, supplier evaluation and supplier development, have a significant impact on the buyer satisfaction while, appropriability and Information sharing dont have significant positive impact on the buyer satisfaction. Finally, the buyer satisfaction has a positive impact on the buyer performance. The result of this study leads supply chain managers to correct understanding of the impact of structural capital on buyer- supplier relationship in order to improve this relationship and performance.

    by Siti Budijati, Subagyo , Muhammad Wibisono, Nur Masruroh 
    Abstract: Companies reverse logistics activity generally is triggered by government regulations and economic opportunities. In reverse logistics decision, consumers behaviour should be considered. This paper presented a study on the influence of government and economic drivers on consumers intentions to participate in a take back program, using structural equation modelling. A survey was conducted on 355 mobile phone users in Indonesia. The study found that the government drivers have more significant influence on consumers intentions than the economic drivers. It was also found that the government drivers served as a mediating variable between perceived environmental regulation and consumers intentions. Moreover, analysis of demographic data showed only the difference in income which significantly affects consumers intentions. These results can be used by the government as a reference to support the mobile phone take back program by applying a special regulation related to the program. In addition, the mobile phone companies can also use these results for implementing the take back program, to consider economic incentives for consumers who participate in the program. Thus, implementation of the mobile phone take back program provides benefits for both consumers and producers for reverse logistics application.

  • Carbon Constrained Dual Sourcing Supplier Selection Problem: A Benders Decomposition Approach   Order a copy of this article
    by Krishnendu Shaw, Ravi Shankar, Surendra S. Yadav 
    Abstract: Carbon constrained supplier selection is relatively newer concept as compared to traditional supplier selection problem. Most of the decision makers face difficulty to select supplier in dual sourcing (global or local) scenarios, which generally have different cost and emission factors. As of now, very few supplier selection models have been proposed taking consideration dual sourcing and carbon footprint issues. This paper proposes a mixed integer based multi-product, dual (global & domestic) sourcing supplier selection model especially considering carbon emission, carbon cap, costs, tax, quality rejection, lead time, various duties and solved using Benders decomposition algorithm. The proposed model is illustrated through a case study and various sensitivity analyses are performed by varying carbon footprint of material, lead time, supplying capacity and minimum order size. Further, this paper helps managers to decide the amount of domestic as well as global sourcing percentages in a carbon constrained situation.

    by Nehemiah Scott 
    Abstract: As environmental complexity and economic turbulence continue to rise, an organizations ability to quickly and continually respond to changing market conditions is increasingly important and heavily reliant on those supply chain capabilities that enable the firm to communicate with their chain partners, streamline supply chain operations and quickly respond to unforeseen industry changes. This responsiveness means that firms must be able to simultaneously balance the conflicting tensions associated with managing existing and growth product markets in a timely fashion. Using the concept of ambidexterity, this conceptual study examines the impacts that a manufacturers ambidextrous supply chain technological capability has on its supply chain integration and ambidexterity in supply chain responsiveness, and ultimately on its performance. Propositions are given, with each one being accompanied by an example from the global semiconductor industry. Lastly, contributions, research limitations, and research and managerial implications are discussed.

  • A closed loop supply chain game between a supplier and a manufacturer in a two stage scenario   Order a copy of this article
    by Rabindranath Bhattacharya 
    Abstract: Tier-I supplier after collection transfers a portion of external return to their supplier in a reverse supply chain in this paper. Supplier derives benefit out of refurbishing of returns. Three scenarios centralized, decentralized and cooperative - decentralised were considered for a two-stage model. Non-linear unconstrained maximizing profitability equations, with normally distributed acquisition prices and deterministic demand were formulated. Solving these for first two models indicated the extent of drop in profit of a decentralized model compared to centralized model. Analysis of cooperative model, based on the results achieved, helps find optimal bounds of transfer and acquisition prices. If both members operate within zone of cooperation, each member earns more profit compared to that in decentralized scenario and overall profit equals centralized one. Study highlights on the decision regarding acquisition price charged by manufacturer for return and transfer price charged by supplier for new product. Decision can be viewed as a contract to arrive at a win-win situation.

  • GREEN SUPPLY CHAIN PERFORMANCE MEASUREMENT: AN EXPLORATORY STUDY
    by Hemantkumar P. Bulsara, M. N. Qureshi, Hiren Patel 
    Abstract: The existing performance measurement tool set for green operations is growing, but may not yet be adequate to assess GSCM in full. The various tools, from the existing literature include tools like the analytical hierarchy process (AHP), activity based costing (ABC), balanced scorecard (BSC) and life cycle analysis (LCA). In keeping the view of having systematic literature, well reputed science cited journals were referred with key word of performance measurement, green supply chain, supply chain performance measurement and green supply chain performance measurement. The search produced 1432 results with either of the above search word. Out of which 112 research papers, proceedings are shortlisted based on their significance for the study and no. of citations. The classification of existing literature follows three tier classification methods termed as classification based on scope, methodology and focus. The present research also includes managerial implications. However, the existing performance measurement tool set for environmental operations lacks adequacy to fully assess GSC from all respect (Yan Li, 2011). A severe need is identified for a single tool for GSCPM that can be used for planning, execution, assessment, and management. The study identifies only a limited set of variables and categorized them in factors such as Operational, Economic and Environmental within both the context. The study does not investigate various other forms of search for new practices such as service innovation.
