  • Technological innovation in the logistics of ethanol and a new systemic model of innovation in logistics   Order a copy of this article
    by Paulo Nascimento 
    Abstract: The purpose of this paper is to model the contribution of technological change in the innovation in logistics services. The approach chosen was four case studies in the supply of ethanol. The result shows that incremental technological innovations have contributed significantly to logistics innovation, not only in information technology, which the literature well reports, but also in storage, transshipment and transport, on which almost silent. Furthermore, the technology is often adopted from outside the organization and tailored to its needs, not restricted to be an organizational factor. The cases also suggest that, even being incremental, the adopted technological innovation, innovation in logistics has a systemic character, overcoming the dichotomy incremental versus radical. This paper concludes incorporating these findings in a new model of innovation in logistic.

  • Multi-Objective Design of Multi-Modal Fresh Food Distribution Networks   Order a copy of this article
    by Marco Bortolini, Maurizio Faccio, Mauro Gamberi, Francesco Pilati 
    Abstract: This paper presents a methodology to jointly minimize the operating cost, the carbon footprint and the delivery time in the design of multi-modal fresh food distribution networks. A tri-objective linear programming model optimizes such criteria overcoming the widely adopted methodologies focused on the network cost minimization, only. A practical selection rule supports the final network structure definition, leading to an effective trade-off among the three objective functions. The market demand supply, the producer capacity limits and the food quality decrease during shipment, i.e. perishability, limit the feasibility region. The paper applies the proposed model to an industrial case study dealing with the distribution of fruits and vegetables from a set of Italian producers to multiple European retailers through a multi-modal (truck, train and air) distribution network. The case study key results suggest the possibility to reduce the CO2 emissions without relevant cost increase.
    Keywords: distribution network, multi-objective optimization, multi-modal shipment, fresh food, supply chain, perishability, carbon footprint, CO2 emissions, sustainability, operating cost, delivery time.

    by Hamidreza Panjehfouladgaran, Rosnah Yusuff 
    Abstract: Companies are trying to increase their market share due to globalization in recent years.Various types of products and customers faced different challenges for companies to achieve market share. Hence, to accomplish this goal, successful companies have to concentrate on the efficiency and effectiveness of their activities. Supply chain involves all activities thatfulfillcustomers demands and transfer materials through downstream into upstream of chain. Since, supply chain creates value for customers and companies simultaneously, monitoring supply chain activities is essential. Numerous performance measurement systems and framework in supply chain have been developed in recent years.This paper discusses on the development of a framework for measuring qualitative metrics in supply chain. Qualitative metrics in supply chain management were identified and then experts selected the most common metrics between them. Fuzzy logic controller was applied to translate verbal expression into numerical variables. Finally, framework was programmed inthe MATLAB

  • Development of New Methods for measuring Forecast Error   Order a copy of this article
    by Allan Valsaraj Mathai, S Narayanan, Dhakshayani Ekambaram 
    Abstract: Forecast accuracy in supply chain is typically measured using the mean absolute percentage error. This however fails when it comes to measuring the accuracy of forecasts of products having intermittent demand. Mean absolute scaled error is a measure of forecast accuracy that works well for intermittent demand and can also be used to compare forecast accuracy between series. In this work, two new methods have been formulated for measuring the accuracy of forecasts with intermittent demand by modifying the MAPE and the SMAPE methods. The denominator of the formula used in the MAPE method will be modified in a way so that it can accommodate for the cases when the demand is zero. In this work, the two new methods have been tested with other methods of measuring forecast accuracy such as Mean Average Deviation (MAD), Mean Average Percentage Error (MAPE), Mean Absolute Scaled Error (MASE), Mean Squared Error (MSE) and Symmetric Mean Average Percentage Error (SMAPE) for data sets of ten products. After performing extensive calculations using data sets from ten products it has been found that the modified SMAPE method performed at par with the MASE method and may be effectively used for measuring the accuracy of forecast of the sales of the various industries with products having intermittent demand.
    Keywords: Intermittent demand, forecast error, error accuracy, Mean Absolute Percentage Error, Mean Absolute Scaled Error.

  • A fuzzy DEMATEL Based Approach for Evaluation of Risks in Green Initiatives in Supply Chain   Order a copy of this article
    by Sachin Mangla, Pradeep Kumar, Mukesh Barua 
    Abstract: The implementation of green/Green Supply Chain (GSC) initiatives is relatively difficult for the point of view of industries due to involvement of different risks. Decision evaluation and assessment of these risks can help industries to formulate strategies and suggest appropriate measures for managing the GSC effectively. For this motive, this paper recognizes the eight evaluation GSC risks with two main dimensions based on relevant literature and ten industrial experts inputs at an Indian plastic manufacturer. The current research proposes to use a fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL) methodology for analyzing the causal relations among the risks. The used fuzzy DEMATEL approach is useful in dealing with human bias and ambiguity involved in studying the interrelationship between the evaluated risks. Research findings indicate that Operational risks and Supply risks have the top significant influences in adopting and implementing effective GSC initiatives in business. Implications for managers and conclusions are discussed in the end.

  • The Effects of Legal-Political Factors and Market Competition on Supply Chain Performance: Some Findings from Firms in a Free Trade Zone   Order a copy of this article
    by Yudi Fernando, Agustina Fitrianingrum, Christopher Richardson 
    Abstract: This paper investigates the effects of legal-political factors and market competition on supply chain performance. The data were collected from firms in the electrical and electronics (E&E) sector in an Indonesian free trade zone (FTZ) on the island of Batam. The E&E firms were chosen because of their significant contribution to Indonesian exports. The sampling of this study was E&E firms involved in exporting activities. As part of survey research, hypothesis-testing was undertaken to explain the variance in the legal-political factors and market competition to predict the two measurements of supply chain performance of the E&E firms in Batam. Since Structural Equation Modeling (SEM-PLS) path modelling 2.0 works efficiently with small sample sizes and complex models, this analytical tool was employed in the study. The findings reveal that legal-political factors and market competition were positively significant on supply chain performance-efficiency and supply chain performance-flexibility. This study suggests that firm success is not necessarily tied to the size of its investment. Rather, it is the interrelationship amongst the factors that influences the supply chain.

  • Weibull vs. Normal Distribution of Demand to Determine the Safety Stock Level when Using the Continuous-Review (S,s) Model without Backlogs   Order a copy of this article
    by Ricardo Manzini, Riccardo Accorsi, Emilio Ferrari, Mauro Gamberi, Valentina Giovannini, Hoang Pham, Alessandro Persona, Alberto Regattieri 
    Abstract: Determining safety stock is one of the most critical issues in inventory and logistics management. rnThis paper presents a cost-based analytical model to determine the best safety stock and customer service level for uncertain demand of products during generic replenishment lead times and a continuous-review inventory system. The proposed model uses the Weibull distribution to model the generic stochastic demand. α and β are the scale parameter and the shape parameter, respectively. An experimental analysis based on the assumption of different distributions of demand of product demonstrates the effectiveness of the proposed model compared to the so-called normal-based traditional model. Significantly, the proposed Weibull-based model is a comprehensible and user-friendly tool that can be useful for production system managers and practitioners.rn

    Abstract: The management of an intermodal terminal, such as Ro-Ro terminals is a complex process that involves several critical decisions. Decision makers should organize operations perfectly in order to prevent bottlenecks and achieve the highest performance. So, predicting and solving possible problems in all processes of a Ro-Ro terminal is vital. At this point simulation modelling is a very useful and common method in analysing port terminal operations because, there are several interacting processes. But there are many simulation programs enable to model terminal operations. However, in which level are simulation software programs reliable in comparison with each other? Can there be significant difference in results of same event modelled by different simulation programs? In this paper comparison of two discrete event simulation modelling software programs, such as Arena and AnyLogic is aimed. Operations of a Ro-Ro terminal are modelled with Arena and AnyLogic independently and results are compared.

  • Production and delivery scheduling problem with delivery times and costs dependent on batch-size   Order a copy of this article
    by Olivier GRUNDER, zakaria HAMMOUDAN, Abdellah EL MOUDNI 
    Abstract: In this paper, we study a real-industrial case of an integrated lot sizing and delivery scheduling problem with multi capacitated transporters and distinct due dates considerations, with batch-size-dependent delivery time and cost.rnThe objective is to find a coordinated lot sizing and scheduling schemernsuch that the total cost is minimized while guaranteeing a certain service level at the manufacturer. A mathematical formulation of the problem is given as a nonlinear model in a general way. We prove a dominance property among the solutions of the problem and propose a generalized dynamic programming scheme to solve this problem in the case of homogeneous and heterogeneous transporters. Then, a mixed integer programming formulation is proposed to evaluate the performance of the dynamic programming method in both cases. Computational experiments show that the proposed approach is very efficient for solving small to medium size instances, especially for the identical transporter case.

    Abstract: Supply chain networks look to transformational leadership and innovation as sources of competitive advantage. Recent theoretical advances have emphasized the need to further investigate these variables in supply chain (SC) literature. The present research attempts to address this call by examining direct and indirect relationships between SC transformational leadership and satisfaction with SC relationships and results. Data from 184 informants was analyzed that showed that SC innovation performance mediated the relationship between SC transformational leadership and satisfaction with SC relationships and results. Furthermore, innovativeness capability moderated the mediation, such that the indirect effect of the SC innovation performance on the relationship between SC transformational leadership and satisfaction with SC relationships and results became stronger under conditions of high SC innovativeness. Based on results, we make suggestions for leadership interventions that include a culture level change within the immediate SC to enhance innovativeness capability through greater integration and motivation to innovate.

  • An integrated inventory model for supplier-manufacturer-retailer system with imperfect quality and inspection errors   Order a copy of this article
    by Wakhid Ahmad Jauhari, Amanda Sofiana, Nughthoh Arfawi Kurdhi, Pringgo Widyo Laksono 
    Abstract: This paper develops an integrated inventory model for a three-stage supply chain system consisting of single-supplier, single-manufacturer, and single-retailer. The demand is deterministic and the production process is imperfect and produces a certain number of defective items. The retailer conducts an inspection process to screen out the defective items from the shipment lot. The inspector may incorrectly classify non-defective item as defective or incorrectly classify a defective item as non-defective.This model provides an optimal solution for the expected integrated total annual cost. A numerical example is presented for illustrative purpose.

  • Information System Outsourcing and Its Impact on Supply Chain Performances   Order a copy of this article
    by Hokey Min, Seong-Jong Joo, Tonia San Nicolas-Rocca 
    Abstract: In the aftermath of recent global financial crisis, many firms consider changing their strategic thinking. Such change includes the reassessment of current business practices that may not necessarily add the maximum value to the supply chain process and may not bring the maximum possible return from the allocated resources. Thus, outsourcing strategy which allows the firm to focus on its core competency has gained popularity over the years. One of supply chain essentials that are often outsourced is an information system (IS) which plays an increasingly important role in facilitating business transactions, aiding decision-making processes, and visualizing assets throughout the supply chain. To help the firm better leverage IS outsourcing, this paper examines whether or not IT outsourcing enhances the firms supply chain performances. Based on the exploratory analysis, we found that supply chain performance is significantly influenced by (1) the size of an outsourcing firm; (2) the degree of the firms recognition of supply chains as its competitive advantage; and (3) the extent of prior IS outsourcing experiences.

  • ISM-Fuzzy MICMAC Approach for analysis of GSCM enablers   Order a copy of this article
    by Anil Dube, Rupesh Gawande 
    Abstract: The object of this paper is to identify the enablers to implement green supply Chain and to understand their mutual relationship. Green supply chain management (GSCM) enablers are identified using available GSCM literature and on consultations with experts from industry and academician. Interpretive structural model (ISM) was developed to identify the contextual relationship among these enablers. A group of experts from industries and academics was consulted and ISM is used to develop the contextual relationship among various GSCMEs for each dimension of GSCM implementation. The results of ISM are used as an input to fuzzy MICMAC analysis, to identify the driving and dependence power of GSCMEs. This paper has identified 14 key GSCMEs and developed an integrated model using ISM and the fuzzy MICMAC approach, Which helps to identify and classify the important GSCMEs and reveal the direct and indirect effects of each GSCME on the GSCM implementation.ISM model provides only binary relationship among GSCMEs, while fuzzy MICMAC analysis provides precise analysis related to driving and dependence power of GSCME. To overcome this limitation, integrated approach is developed.This study has strong practical implications, for both practitioners as well as academicians. The practitioners need to concentrate on identified GSCMEs more cautiously during GSCM implementation in their organizations and the top management could formulate strategy for implementing these enablers obtained through ISM and fuzzy MICMAC analysis.

    by Hassan Mukhtar, Andrea Schiffauerova 
    Abstract: A well-organized supply chain network increases the efficiency of the supplier selection and improves quality of service. However, certain barriers to suppliers quality management prevent companies from achieving these gains. The aim of this study is to identify important barriers that affect suppliers quality management and to determine the contextual relationships between them using Interpretative Structural Modeling approach. Based on literature review seven important barriers to quality management were identified at the supplier level and a graphical approach was then used to classify these barriers into multiple categories. Experts opinion from Saudi industry was sought to develop Structured Self-Intersection Matrix and Reachability Matrix, which are used to identify binary relationship among these barriers. The study provides new insights into understanding of the critical factors hindering successful supply chain management.

  • A new approach for evacuation process in disaster relief with uncertainties   Order a copy of this article
    by Minoo Kazeminia, Hossein Naderi, Ali mohamad Ahmadvand 
    Abstract: In this paper, a new mathematical model is presented for evacuation and relief management in case of disasters. Since these kinds of phenomena contain remarkable uncertainties, fuzzy theory is used to deal with it. When a disaster happens, travelling times between each two nodes are not certain. To this aim, a fuzzy inference system is employed to predict travelling times. And, different scenarios are designed to cover various conditions and to reach the optimum decision. Size of scenario tree exponentially increases by increasing number of nodes and arcs. Consequently, in large-sized problems a huge scenario tree is resulted and the problem becomes too complex to deal with in terms of exact solution. Therefore, scenario tree size reduction is inevitable. Finally, to validate the proposed model several small and medium-sized problems are solved by GAMS software that indicates acceptable efficiency of the model. In addition, sensitivity analyses are made on budget and demand parameters to determine models behavior upon these parameters.

  • Investigating links between low-level inventory practices and business performance   Order a copy of this article
    by Dimitrios Folinas, Thomas Fotiadis 
    Abstract: The paper investigates the effects of low-level inventory practices on financial performance in the Greek manufacturing industry by examining past literature reviews and empirical evidences of a primary research. To enhance research reliability, consistency, and validity of the quantitative research a systematic (step-by-step) research design is created to ensure quality in the data collection techniques, data analyses and interpretation, and the links between the literature reviews and the results investigated. The results of this study suggest that there is not a strong link among low-level inventories management practices and financial based performance indicators even if the manufacturing companies have remarkably applied these practices during the last years. Therefore, it is proved that the examined investigation must be viewed from more business dimensions (such as sales and marketing).

  • Model for Identification of Effects of Demand Prediction on Bullwhip Effect Using Adaptive Network-Based Fuzzy Inference System (ANFIS)   Order a copy of this article
    by Nazanin Pilevari 
    Abstract: The prevailing paradigms in the area of today's business are the supply chains and their management. The purpose of supply chain management is to lower the overall cost of chain and this has led to the chain being in need of mutual collaboration of its components. One of the phenomena that expose the coordination of supply chain to challenges is a phenomenon called the bullwhip effect. Following the study of previous research and using the expertise of experts, this research identifies the effective components on the quantity of demand. Then, seeking the opinion of experts in the industry under study (the automotive parts industry) and using the MATLAB software, the set of rules for fuzzy inference system were exploited and the model for prediction of single-level supply change was developed. Moreover, the developed model was implemented in the studied organization (PAYA CLUTCH COMPANY). Furthermore, in order to assess the effect of developed model on bullwhip effect, the results of conducted predictions were compared to each other through the conventional model and technique of company (regression method) and the trend analysis method. The results suggest that the model developed using adaptive network-based fuzzy inference system leads to less bullwhip effect than regression and analysis methods.

  • Advance demand information and early fulfilment in inventory management with two demand classes   Order a copy of this article
    by Sourish Sarkar, John Shewchuk 
    Abstract: This paper investigates the use of advance demand information in three inventory models, each serving two demand classes. The first model is a periodic-review pure inventory system with advance demand information from both classes. The second model considers continuous review production-inventory system, where only one class provides advance demand information. In the third model, both demand classes provide advance demand information, though only one class accepts early fulfilment. Optimal inventory replenishment policy is characterised in the first model under certain conditions. In the remaining two models, simulation-optimisation methods determine the optimal Kanban-based early fulfilment policies. Presence of a small fraction of customers, who agree to provide advance demand information and accept early fulfilment, is shown to be more advantageous than having all customers with same amount of advance demand information but no early fulfilment. Managerial insights are drawn in certain scenarios.

  • Optimality of Cycle Time and Inventory Decisions in a Coordinated and Non-coordinated Three-Echelon Supply Chain under Exponential Price Dependent Demand   Order a copy of this article
    by Burra Karuna Kumar, Dega Nagaraju, S Narayanan 
    Abstract: To remain competitive in the prevailing stiff business competition, coordination among the entities of the supply chain is becoming mandatory. The people in the supply chain have to integrate their business decisions beyond the organizations boundary. This paper develops a mathematical model for a coordinated and non-coordinated three-echelon supply chain under exponential price-dependent demand. The model is developed with the consideration of ordering/setup, carrying and transportation costs. The objective of this work is to demonstrate the optimality of inventory replenishment decisions, shipment frequencies and the annual total variable costs, with and without coordination. A numerical illustration is presented to determine the optimal values of the objective function and decision variables. Further, the sensitivity analysis is carried out to study the influence of the model parameters on the optimality of decision variables and the objective function.

  • Innovation management in logistics: an empirical study   Order a copy of this article
    by Ingrid Göpfert, Wanja Wellbrock 
    Abstract: In this study we examine the extent to which innovation management is established in business logistics. In addition to the general implementation of an innovation management the study is also focused on the importance and success of innovations for logistics, the underlying innovation process, corresponding expanses to achieve logistics innovations and relevant innovation triggers. To get significant results we carried out a questionnaire under the each 100 largest German companies of eight selected industries. In total we integrated 800 companies in our study and got a response rate of eleven percent. As main results we show that despite a fundamentally high importance of innovations in logistics, the corresponding expanses are still relative small. Innovation management is not yet sufficient implemented in the area of logistics and a structured innovation process is also absent in the majority of companies surveyed. Moreover we show that innovation management is mostly limited to a single company and a continuous enterprise-wide expansion would be desirable for the future.

    by Vinayak Vishwakarma, Chandra Prakash, Mukesh Kumar Barua 
    Abstract: Being a highly significant part of health care system, developing nations pharmaceutical industry, supplying medicines across world needed to develop risk averse supply chain to protect global health of human beings and businesses. However, the successful accomplishment of pharmaceutical supply chain (PSC); production and business activities are relatively difficult due to involvement of different risks. Therefore, identification of risks and their subsequent analysis of PSC are very important. Any risks affecting the pharmaceutical corporations could interrupt supply medicines and health systems effectiveness. This paper proposes multi criteria decision making (MCDM) methodology based on fuzzy AHP approach to prioritize and rank risks in PSC. This approach is also suitable in analyzing experts judgments and uncertainty involved in the process of risk assessment. This study identifies twenty four risks under five major risk measures of Indian PSC through relevant literature and experts opinions. The results of study would be beneficial for industries in managing and reducing the consequences of the risks in PSC. The analysis of the results indicates that supply and supplier risks are the most important risks in Indian PSC. Sensitivity analysis is also performed to test the robustness of the proposed approach.

  • Justification of Green Logistic Practices in Indian Enterprises using analytic hierarchy process   Order a copy of this article
    by Deepti Chhabra, Rajesh Kumar Singh 
    Abstract: Logistics is the integrated management of all activities which are required to move products through the supply chains. By practicing greening efforts in the logistics system, manufacturing enterprises may have efficiency improvements and several other long term benefits in addition to the basic objectives of achieving the organizational goals of the manufacturing enterprises. This paper is intended to justify the green logistics practices over non-green logistics in the manufacturing enterprises. The justification is done by using Analytical Hierarchy Process. On the basis of literature, major benefits of green logistics have been identified and enlisted as energy saving, reduction in carbon emission, protection of ecological environment, managing waste disposal, reduction in distance and quality improvement. The global desirability index of green logistics over non green logistics are calculated by using AHP and then compared to justify green logistics over non green logistics in the Indian manufacturing enterprises. Furthermore green logistic concepts are studied through a case study.

  • Supply Chain Risk Management in the Indian Manufacturing Context: A Conceptual Framework   Order a copy of this article
    by V Viswanath Shenoi, T N Srikantha Dath, Chandrasekharan rajendran 
    Abstract: Due to emergence of global business environment, short product life cycles, technological innovations, natural disasters and ever changing government policies, industries face various types of risk in their supply chains. To overcome the increased risks raised by the above factors in the supply chain, organizations need to establish the principles of Supply Chain Risk Management (SCRM) for serving customers by finding right suppliers and fostering the trust among the supply chain partners. This study proposes that by following the strategies such as risk plan, risk financing, risk monitoring, risk avoidance, risk transfer and risk sharing, the supply chain can be enhanced by reducing the impact of risk on supply chain. This study supposes that the supply chain partners (entities) need to share information transparently across the supply chain to enhance the visibility of the supply chain.Without sharing information across the supply chain, alleviation of the impact of the risk and sustaining long lasting relationship among the trading partners is a difficult task. This study attempts to identify the critical dimensions of SCRM and it develops a conceptual framework to understand the relationship between risk and performance measures from the perspective of the manufacturers which includes Original Equipment Manufacturers (OEM), Tier-1 and Tier-2 suppliers.

    Abstract: The purpose of this study is to explore the interfaces and driving forces between the elements of the Triple Bottom Line (TBL) approach. A qualitative study was undertaken with respect to a sample of reputable companies in Norway, which have implemented significant business sustainability programs within their organizations, the marketplace and in the society beyond mere compliance. The results form the study is that there appear to be no established structures or processes that enable an insightful understanding of driving forces and interfaces between the TBL-elements. The article outlines a framework for the fragmented state-of-the-art practices is labeled TBL Management. This is an attempt to emphasize not only the measurement properties of the TBL-elements (economic, social and environmental ones), but also the structural ones (cause-and-effect between elements) that have so far not been recognized in practice and theory.

  • Integrated versus Individual Approach in Products Distribution Networks   Order a copy of this article
    by Lamia Triqui-Sari, Jean-Claude Hennet, Zaki Sari 
    Abstract: The purpose of this paper is to compare the effectiveness of two approaches for inventory management in a network of retailers. In the individual approach, each retailer independently orders products from the central warehouse at the beginning of the commercial season, when demand is still uncertain. In the integrated approach, the first stage of ordering from the central warehouse is followed by a process of exchange of products between the retailers once real demands are known with certainty. In terms of modeling and methodology, the basic newsvendor model specializes in the case of discrete probability distributions. The compound distribution generates scenarios that allow solving the stochastic optimization problem of expected profit maximization as a deterministic problem. A real industrial example provides a numerical application in this study. The results indicate that the integrated approach increases the total expected profit of the network. It also improves the service level for customers and the efficiency of transport.

  • Challenges and Opportunities for Implementing X-ray Scanning Technology at the Korean Hub Ports   Order a copy of this article
    by Hokey Min, Jong-Won Park, Yong-Kon Lim, Aerim So, Yong Kap Cho 
    Abstract: Over the last few years, a series of legislative attempts to mandate 100% scanning of cargo containers bound for the U.S. has pressured foreign port authorities to adopt more efficient container inspection strategies. One of such strategies includes the adoption of X-ray scanning technology at foreign exporting port facilities which can provide clear and unobtrusive views of the contents of items hidden inside containers before they are shipped to the U.S. destination ports. Despite numerous benefits of using X-ray scanning technology, maritime industry sectors and port authorities still are hesitant to utilize it for a number of concerns. Those concerns include: ambiguity and costs associated with 100% container scanning policies, potential technical glitches, and logistics inefficiencies created by lengthier lead time. To address these concerns, this paper identifies a multitude of factors that may hinder the efficient use of X-ray scanning technology in the Korean hub ports from the perspectives of carriers. Also, this paper aims to assess the spillover effects of X-ray scanning technology adoption on port revenue.

  • Assessing the Responsiveness of Supply Chain - Structural Equation Modeling Based Approach   Order a copy of this article
    by Raghuram Potluru, Saleeshya Parakkal 
    Abstract: Companies worldwide have now realized that customer focus is what wins the game. As demands of the customer become more and more volatile and unpredictable, they have to stay ahead of their competitors in fulfilling the needs of the customer. The supply chain as a unit has to compete against other supply chains for reaching out and delighting the customer. Responding fast to the changing customer needs has been an intangible factor underlying a successful business. Thus, responsiveness of the supply chain has become the differentiator between the competing supply chains. In this paper, the end-to-end supply chain factors influencing responsiveness are identified from extant literature and a model of responsiveness of the supply chain has been developed by conducting a survey of 204 pump manufacturers. The developed model has been validated through confirmatory factor analysis using structural equation modeling. These findings can help to identify the areas of improvement for the supply chain and may lead to a focused improvement in these areas thus improving responsiveness and profitability.

  • A bi-objective location inventory model for three-layer supply chain network design considering capacity planning   Order a copy of this article
    by Abolfazl Kazemi, Hamed Iranmanesh 
    Abstract: This paper aims at bi-objective optimization of single product for three-layer supply chain network consisting of a factory, distribution centers (DCs) and customers including the impact of inventory management system. The key design decisions are: The location of DCs and their capacity, production capacity of the factory, product quantity to be transported from factory to each DC, product quantity to be transported from each DC to each customer, and order quantity at DCs, so as to minimize the sum of the production cost, location cost, transportation cost, ordering cost, inventory holding cost, and lost sales. The problem is formulated as a Mixed-Integer Non-Linear Programming (MINLP) model and solved using GAMS solver and proposed meta-heuristic algorithm. The -constraint method is used as solution approach to tackle the multi-objective problem when using GAMS. Because of NP-hardness of the problem, a hybrid meta-heuristic algorithm based on genetic algorithm is proposed to solve large scale problems. Computational experiments demonstrate the effectiveness of the proposed model and algorithm in designing large supply chain networks.

  • How Do Different Supply Chain Configuration Settings Impact on Performance Trade-Offs?   Order a copy of this article
    by Yasmine Sabri, Guido J.L. Micheli, Cali Nuur 
    Abstract: The notion of 'fit' in the supply chain management literature (SCM) has evolved following the adoption of the contingency approach in an endeavour to achieve greater organisational effectiveness. In this paper, we investigate the possible approaches to achieving a state of fit between supply chain configuration settings and performance indicators, while taking into account the contextual factors related to different industry sectors and geographical dispersion levels. This study addresses the pressing issue of the performance trade-offs faced by companies to achieve a higher service level and customer satisfaction (effectiveness) on the one hand, while being cost-efficient on the other hand (efficiency). The paper contributes to the SCM literature and practice through synthesising a conceptual framework that scrutinises the relationships between six individual configuration settings and nine effectiveness/efficiency indicators. The studys findings explain the motivations behind different configuration decisions, which help in obtaining the most appropriate fit between supply chain configuration and performance.

    Abstract: Coffee supply chain management is the global operational strategy for enhancing the competitiveness of coffee companies. Enterprises are attempting to find ways to improve their competitiveness by changing their operation strategy through methods that include the implementation of the supply chain management paradigm. However, a thorough and critical review of existing literature is yet to be carried out in order to identify pertinent factors and gain useful insights into the role and effectiveness of causal loop modelling in coffee supply chain management. In this paper, researchers develop causal relationships among different variables that present enablers and outcomes operating within many identified feedback loops. The resulting causal loop model provides coffee production managers with a snapshot of the dynamic interactions among elements in the coffee supply chain, which helps to identify proactive action in implementing the coffee supply chain philosophy for increasing the competitiveness of coffee products. Based on this review and analysis, recommendations are made regarding the application of the causal loop method in coffee supply chain management. Important future research directions are also indicated.

  • Development of an Inventory Model for Two Suppliers with Random Capacity considering Supply Disruption   Order a copy of this article
    by Imtiaz Ahmed, Ineen Sultana, Abdullahil Azeem 
    Abstract: In todays complex supply chain system supply disruptions due to occasional unavailability of raw materials or products pose serious consequences for firms and are thus of particular concern for strategic decision makers. Supply disruption occurs for diverse reasons including transportation problem, equipment failure, raw material shortages, natural calamities etc. If any of the above reasons occurs supplier may become unavailable at random times for random time length. Besides,in reality in many cases suppliers may have random capacities which will lead to uncertain yield in orders. Again under random supplier capacities, the retailer should order from a number of suppliers in order to diversify the risk associated with shortages. The objective of this paper is to develop an inventory model for two suppliers with random capacities considering supply disruption. A modified (Q, r) model is developed to tackle the problem of future supply uncertainty in response to the demand generated by Poisson process. Two suitable optimization algorithms are applied to search for the optimal values of the decision variables which are state dependent order quantities and reorder point to minimize the cost per unit time.A hypothetical example and its solution are then provided to have a better understanding about the demonstration of the proposed model. Finally sensitivity analysis is also carried out to have better insights about the model developed.

    by Sooksiri Wichaisri, Apichat Sopadang 
    Abstract: This paper presents to identify opportunities and gaps of research for the integration of sustainable development, lean, and logistics concepts into a lean sustainable logistics model. Conceptual evaluation is the first step to understand the main points and link each concept. These concepts consist of four components, including the goals, elements, benefits, and limitations of each. The three relationships investigated in this research consist of the interfaces of sustainable development and logistics management, sustainable development and lean concept, and lean concept and logistics management. Following the conceptual evaluations and interfaces among them, the three concepts are integrated into a lean sustainable logistics model. There are four stages, comprising discordant action, proficiency, cooperation, and interdependence, for analyzing the constructed model combination of lean sustainable logistics. Then the lean sustainable logistics model can be synthesized for implementation in organisations to achieve long-term benefits.

    by Rajkanth Raju, Srinivasan G, Mohan Gopalakrishnan 
    Abstract: This paper addresses a distribution problem in a multi-product, multi-echelon supply chain. We develop a Mixed Integer Linear Programming formulation that considers allocation of vehicles with varying capacities for the transportation of products between the stages of the supply chain. The cost of transportation includes the fixed and variable costs of using the vehicles. The proposed formulations are solved optimally up to certain sizes, and we propose a heuristic based on Total Opportunity Penalty Cost Method to solve the large sized problems. These proposed solution procedure is tested over a set of hypothetical problem sets. The results indicate that the proposed heuristic algorithm yields solutions within 5 percent from the optimal solutions.

  • Reselection of logistics service provider: The meaning of the experience in the reselection process   Order a copy of this article
    by Kai Häkkinen, Outi Kettunen 
    Abstract: The research focus in this study is on the reselection problem of the logistics service provider (LSP). The problem was studied with one Finnish metal industry company. Our idea was to test whether the experience gained during the last eight years has changed the importance of the selection criteria and brought any new selection criteria to the table. We created a new framework in part based on the User Experience (UX) research field, which appears to be useful in the context of our study. The study is a pilot study to test the suitability of the incorporating the UX research field concepts into the logistics research field. The proposed new framework appeared to function well. The study showed that non-verifiable selection criteria require more attention than verifiable criteria. Additionally the study brought out three selection criteria that are not used in the literature as far as we know.

    by Aylin Caliskan, Mustafa Kalkan, Yucel Ozturkoglu 
    Abstract: The city logistics is the multidisciplinary science that makes a bridge between both urban freight transportation and sustainability of the cities. It has also focused on various subject matters such as populations, facilities, traffics and logistics activities. If all this dynamic criteria consider, different logistics scheme must be prepared for each city. Cities have to be handled and analyzed individually according to their own characteristics. In order to understand the current situation and problems of urban freight transport in Turkey, this paper examines the specific focus on Turkeys third largest city Izmir in terms of city logistics with the eye of logistics service providers. A qualitative approach was used and unstructured interviews with subject matter experts were conducted to gain general insight into how logistics service providers perceive the problems in city logistics in Izmir and the solutions they propose. Regarding the gap between theory and practice, this study would be valuable for future research in city logistics studies, and the results of the study would be a practical tool for decision makers in their city logistics planning process.

    Abstract: Selective collection has grown over the last few years and this is leading to an increase of the reverse logistics costs paid by the City Hall. Thus, a better planning of the reverse logistics may reduce costs by minimizing the number of trucks needed and the total distance travelled. This paper proposes a mathematical model and a modified Simulated Annealing metaheuristic based on the Vehicle Routing Problem with Multiple Trips to plan the reverse logistics for the selective collection. The mathematical model was solved by CPLEX 12.6 and the SA was developed in C. In order to test both of them, they were applied to the selective collection in five Brazilian cities that use a Volunteer Delivery Stations (VDS) located at roads and squares. SA performed the planning of selective collection in a relatively low computational time and achieved a better plan than the ones done manually by the planners.

  • Factors Affecting the Competitiveness of the Australian Rail Sector: A Systems Approach to Improving Service Quality   Order a copy of this article
    by Hadi Ghaderi, Stephen Cahoon, Hong-Oanh Nguyen 
    Abstract: The productivity of rail freight transport in Australia is hampered by various impediments. These include infrastructure constraints, commercial barriers, and inconsistent standards and policy, all of which influence the quality attributes of the rail freight service in different ways. Therefore, in order to develop strategies to make rail an attractive mode of transport, it is critical to identify these impediments and assess their relevant influence on the quality of rail service. By adopting a systems approach to competitiveness, this research aims to empirically examine the impact of impediments faced by the rail sector. This approach is beneficial as it: (i) identifies the distinct impact of each impediment on the different freight service attributes (FSA); (ii) provides important insights to improve the rail service quality; and (iii) aims to assist government and industry to develop informed transportation and infrastructure planning decision making by identifying the poorer performing areas of system. The analysis identified the key factors influencing the quality of different FSAs relating to (i) infrastructure management; (ii) interoperability; and (iii) organisational and commercial relationships. The implications derived from this study indicate that the freight rate is still a key area for rail to achieve competitive advantage considering the market characteristics.

  • A Hybrid Approach using Data Envelopment Analysis & Artificial Neural Network for optimizing 3PL Supplier Selection   Order a copy of this article
    by Rakesh Raut, Sachin Kamble, Manoj Kharat, Hemendu Joshi, Chirag Singhal, Sheetal Kamble 
    Abstract: Today third-party logistics (3PL) service providers are into almost all the businesses right from providing raw material to packaging. 3PLs are also getting involved in customers concerned with operations. At a suitable price and consideration of all affecting criterias anything can be outsourced. Any exporter needs to find a smart balance of what to perform in-house and what to hire outside providers to do (i.e. increase verticals and reduce horizontal Supply Chain operations). Thus, the demand of 3PL provider has become an important issue for organizations seeking quality customer service and cost reduction. The current research presents an integrated data envelopment analysis (DEA) and artificial neural networks (ANN) methodology for the evaluation and selection of 3PL providers. DEA is employed to identify the maximally efficient 3PL and to eliminate the unsuitable ones; and, ANN to rank and make the final selection. The proposed method enables decision makers to better understand the complete evaluation and selection process of 3PL selection. Furthermore, this approach provides a more accurate, effective, and systematic decision support tool for 3PL selection. Finally, an actual industrial application is presented to demonstrate the proposed method.

    Abstract: Managing independent members who share common goals is a frequent concern in any supply chain. More specifically, due to the critical role of the pharmaceutical industry in producing and delivering the right product to the right people at the right time, coordination of pharmaceutical supply chain (PSC) members is a critical factor. Therefore, the purpose of this study is to identify and prioritize factors affecting coordination of a PSC. The analytic hierarchy process (AHP) is used to prioritize six strategic criteria, with 26 sub-criteria, for coordinating PSC operations. To run AHP, 44 interviews were performed to collect data for deep analysis. In this study 26 factors affecting coordination in a PSC were grouped to the six strategic factors. The results showed that, of these factors, organizational structure is perceived as the most important factor, followed by information technology, relationship and decision-making, mutual understanding, management commitment, and regulatory affairs.

  • Inventory management of perishable products in a retail business: A comparison with and without in-store replenishment policies under different purchasing batch sizes   Order a copy of this article
    by Navee Chiadamrong, Rigzin Lhamo 
    Abstract: Perishable products are products in daily life that expire or decrease in quality or value over time. As their freshness level decreases with time and inventory is lost by deterioration with time, traditional methods for managing inventory are not suitable for perishable products. Additional mechanisms are then required to manage the inventory of such products. In the study, taking into consideration the age of perishable inventories, these mechanisms are investigated in different scenarios, and with different cost combinations to study the effect on the inventory management of perishable products. The outcomes of the replenishment policies under different purchasing batch sizes with and without a backroom are also compared to find out how and in what situations the policy with backroom storage outperforms the others and can lead to cost reduction and higher profit as compared to the case without backroom storage. These findings help firms decide the best policy for managing perishable products in a certain business environment.

  • Developing decision support system for heterogeneous fleet vehicle routing problem using hybrid heuristic   Order a copy of this article
    by Nitin Sakhala, Jitendra Jha 
    Abstract: In last few years, there has been an increasing use of optimization packages and decision support system (DSS) for the efficient and effective decision making. A significant variant of vehicle routing problem (VRP) arises when a fleet of vehicles is characterized by different capacities and operating costs, which is known as heterogeneous fleet vehicle routing problem (HFVRP). This paper aims at determining the optimal composition of fleet and set of routes to be accomplished by a fleet of heterogeneous vehicles for serving a given set of customers with the objective of minimizing the total routing cost. To obtain the solution of the HFVRP, implementations of construction heuristics (savings algorithm, nearest neighbour, branch and cut) and improvement heuristics (2-Opt and Or-Opt) are achieved through development of a DSS which eventually leads to proposal of a hybrid heuristic for route optimization.

    Abstract: It is necessary to discover the influential factors on consumers intentions and behaviour to develop an effective reverse logistics. This paper presents an evaluation of the influence of environmental attitude on consumers intentions to participate in the mobile phone take back program. The evaluation was based on a survey toward 355 mobile phone users in Indonesia and implemented a structural equation modelling. The result showed that environmental attitude had positive and significant influence on consumers intentions. Furthermore, the factors that influence positively and significantly on environmental attitude were ethics and control, while environmental value had a positive influence on environmental attitude but not significant. From this result, it is noteworthy for mobile phone companies that in promoting the take back program they need to bring out the ethical and self competence themes to inspire the environmental attitude of the consumers.

    Abstract: The break-bulk trade has a significant role in international maritime trade. Brazil exports several break-bulk cargoes, especially granite blocks. The port administration should plan the yard operations, putting more granite blocks in the same area and also reducing the distance traveled by the trucks from the storage yard to the seaside. This paper proposes a mathematical model to plan the layout of the storage yard, named 3D-Yard Allocation Problem (3D-YAP) that considers that a small block goes on top of a big block, only blocks from the same vessel can be stacked in one stack and blocks can be rotated on the X-Y plane. The model was tested on instances based on real data from Praia Mole Terminal (PMT), Brazil, that were solved by CPLEX 12.6. It is also important to say that the model can be applied to any kind of break-bulk cargo in any port yard or terminal.

    Abstract: In recent era, the creation of electronic contraptions is expanding step by step, which leads tremendous electronic waste. This is the condition drives as a result of the current individuals expecting new innovation in a brief time. This circumstance makes the manufacturers in a circumstance to create the new item in a brief time, so the current items need to either disposed or dismantled. In this circumstance the manufactures wanted to re-manufacture the end-of-life (E-O-L) items to meet the component necessity in the new items production. In this sense in our previous work we exhibited a methodology to choose the optimal number of take back product, so that the aggregate expense needed for the reverse logistic (RL) can lessened. In this paper we exhibited a novel methodology for the RL operation of E-O-L items, in view of an optimal scheduling algorithm. In the previous work we have locate the optimal number of take back E-O-L products for the disassembly-to-order (D-T-O), and this paper displayed the procedure to legitimately schedule the machines to disassemble the products, so that the aggregate time as well as the total cost needed for the RL operation can diminished.

    Abstract: In both commercial and non-for-profit logistics networks, collaboration among supply chains could be an important strategic resource. Even more, the integration of the supply chain could guarantee the efficiency of the different chains involved in such operations. This paper considers a tactical model for the optimization of a commercial supply chain model, inspired on a previously developed post-disaster logistics model; the model involves the cooperation among the different suppliers of the supply chain. In order to evaluate the effect of cooperation among the different competitors, a logistic network was simulated and several cooperation scenarios were considered, based on the strengths of each one of the actors involved. The model aims for the minimum cost of supplying a specific item for the network and, at the same time, it allows for the different suppliers to observe their benefits of cooperation. Cooperative game theory is approached and Shapley value is calculated in order to determine the distribution of costs as well as the utilities of the players involved, determining feasibility of the cooperation scheme designed.

  • Designing an integrated multi-echelon supply chain network with competition   Order a copy of this article
    by Isa Feyzian-Tary, Jafar Razmi, Mohamad Sadegh Sangari 
    Abstract: This paper develops a model for competitive supply chain network design which investigates competition between new and existing chains where demand is deterministic and price-dependent. The network consists of raw material suppliers, manufacturers, retailers, and demand market. The supply chains compete in a non-cooperative manner and manufacturers produce homogeneous products. The objective is to maximize the future profits of both chains. First, the problem is formulated by mathematical programming and Lagrangian theory is used for adding the constraints to the objective function. Then, the equilibrium conditions are derived and the problem is formulated as a finite-dimensional variational inequality model. Qualitative properties of the equilibrium pattern are derived to establish existence and uniqueness results under reasonable conditions. The modified projection method is used to solve the variational inequality problem. Finally, a numerical example is presented to illustrate the efficiency of the proposed model and analyze the results under different conditions.

    Abstract: This paper aims to analyze the perception of port users about the governance actions in the Port of Santos (Brazil). This is an important approach since most studies regarding port governance address governance structure and port functions, but do not consider the actions to be taken to improve the coordination of port logistics chain. The sample considered was composed by experienced managers of 30 international freight forwarders that operate in the referred port. In order to ensure the quality of the sample were selected only managers with higher education and at least 5 years experience in the studied sector. Through a quantitative and descriptive approach, with data collection by means of a survey, the different governance actions related to four dimensions of a considered governance model were evaluated from the perspective of users. The results indicate that the Port of Santos develops governance actions incipiently in all dimensions, revealing that the management of the port still needs to evolve to achieve a higher level of coordination.

  • Strategic Outsourcing Objectives Drive 3PL Selection Criteria in India   Order a copy of this article
    by Vijayakumar Sangam, Himanshu Shee 
    Abstract: This paper examines the extent to which supply chain outsourcing objectives determine the selection criteria for 3PL service providers. While the 3PL selection criteria are researched earlier, there is little understanding how they are influenced by the strategic objectives of an organisation. Using a cross-sectional survey of 297 logistics and supply chain professionals from across industries in India, structural equation modeling (SEM) analysis reveals that strategic outsourcing objectives are the likely predictor of the 3PL selection criteria. The respondents perceived higher customer satisfaction, reduction of ICT legacy systems, capital investment avoidance and access to state-of-the art technology that influence the decision on selection of 3PL service provider. The findings provide shipper managers an insight on how to purposefully assess the selection criteria ensuring their alignment with strategic objectives of outsourcing.

  • A two warehouse inventory model for deteriorating items with variable demand under alternative trade credit policy   Order a copy of this article
    by Ali Akbar Shaikh 
    Abstract: In this paper, we have developed an inventory model for single deteriorating items with two separate storage facilities (own and rented warehouses) due to limited capacity of the existing storage i.e., own warehouse considering allowable delay in payment. The demand rate of this item is dependent on continuous time, selling price of the item and the frequency of advertisement. Partially backlogged shortages are allowed with a rate dependent on the duration of waiting time up to the arrival of next lot. To formulate the model, we have considered different realistic situations. The corresponding problem has been formulated as constrained non-linear mixed integer problem and solved by Generalised Reduced Gradient (GRG) method. Finally, a numerical example has been considered to illustrate and validate the model. Sensitivity analyses have been carried out by changing one parameter at a time and keeping the other at their original value.

  • A Genetic algorithm based approach for unbalanced assignment problem in interval environment   Order a copy of this article
    by Asoke Kumar Bhunia, Amiya Biswas, Subhra Sankha Samanta 
    Abstract: The goal of this paper is to propose an approach based on genetic algorithm for solving unbalanced assignment problem with lesser number of agents than the number of jobs under the assumption that the cost/time for assigning a job to an agent is interval number. Also an additional constraint on the maximum number of jobs allowable to agent(s) is considered. In the proposed approach, the existing real coded genetic algorithm is extended for interval valued fitness with the help of interval order relations (Bhunia and Samanta [12]) and two different versions of algorithm based on two crossover operators is developed, one is newly proposed Extended One-point Crossover and the other, Inverse Exchange Crossover. Then, to test the performance of different versions of the algorithm and also for the practical demonstration of the problem, three test problems are considered and solved. Finally, a fruitful conclusion is drawn regarding the performance of both the versions of genetic algorithm.

  • Risk Management Process towards Operation Performance in Supply Chain Management: A Survey of Manufacturing SMEs   Order a copy of this article
    by Ali Haj Aghapour, Govindan Marthandan, Gun Fie Yong David, Suhaiza Zailani 
    Abstract: Risk management has become an important area in supply chain management since the late 1990s. However, less empirical studies have been reported in the literature that links risk management practices to performance, especially among SMEs. This paper aims to empirically investigate the sequential impact of this managerial process on non-financial performance of three execution decision areas of the SCOR model. Therefore, a cross-sectional study was conducted among manufacturing SMEs in Iran. Data was collected from 160 high managers with knowledge of past and present organizational practices. Using partial least squares modeling (PLS-SEM), analysis of manufacturing plants from six industries indicates that superior risk identification supports the subsequent risk assessment and this in turn leads to better risk mitigation. The model also explains 38% of the variance observed in supply chain operation performance. Accordingly, to ensure better supply chain operations in terms of reliability, flexibility and responsiveness, cost and assets, the findings of this study recommend SMEs to pay more attention towards risk analyzing practices on one hand and distribution KPIs on the other hand. However, the study was based on decision makers perceptions and the participation of divergent industries creates common limitations and future research orientations.

  • Supply chain performance measurement using SCOR model based on interval-valued fuzzy TOPSIS   Order a copy of this article
    by Arezoo Moharamkhani, Ali Bozorgi-Amiri, Hassan Mina 
    Abstract: Performance measurement is known to be the best way of investigating the supply chains' success. In this regard, managers can identify the root causes of weakness points and improve supply chain's performance through analyzing and solving these problems. Concerning this problem, various supply chain performance evaluation models have been presented in literature. Through all of the models, this paper used Supply Chain Operations Reference (SCOR) model for performance measurement of three Iranian automotive supply chains. First SCOR model is employed to define the performance criteria. Afterwards, Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is used to determine the supply chain that performs best. In this paper, experts judgment is used to determine the criterias value and weight but uncertainties in experts judgment was unavoidable, also experts cannot reach an agreement on the method of defining linguistic variables based on fuzzy sets. So, paper used interval-valued fuzzy set to solve these problems. To the best of authors knowledge, this is the first study that have applied interval-valued fuzzy TOPSIS in group decision-making in order to evaluate and improve the performance of supply chains on the basis of SCOR model.

    Abstract: ABSTRACT: rnPurpose Global population growth exerts tremendous effect to the extent of constraining the food supply chains. Consequently, this calls for serious efforts in minimising food wastes upheld in agro-supply chains. Fresh vegetables are perishable in nature hence more vulnerable to postharvest losses (PHLs). This paper aims at determining PHLs experienced and establish the most prone channel for high PHLs.rnDesign/methodology/approach This study employed a case study strategy. Both primary and secondary data were collected using self-administered questionnaire. The questionnaires were distributed to a multistage sample in five popular vegetable markets of Kilombero, Arusha Central Market, Samunge, Jakaranda and Unga Ltd in Arusha city. Analytical methods were used to determine PHL both in terms of quantity and value as well as the profitability achieved by last-mile traders using tomatoes, carrots and cabbage as selected vegetables.rnFindings The study found out that more PHLs occur at the retail stage and is more than twice compared to the amount at the wholesale stage. Cabbage exhibited the lowest turnover rate followed by carrots and tomatoes. Similarly, cabbage registered the highest PHL rate followed by tomato and carrots. On average, wholesalers cum retailers registered a PHL rate of about three times those of wholesalers per se. Retailers constituted 70% of respondents who acknowledged to have faced PHL. It was also found that, the longer is the chain the more PHL was sustained. rnOriginality/value The vegetable PHLs in Tanzania has remained understudied, and this study tried to cover this gap in academia.rn

  • A fuzzy mathematical model for supplier selection and order allocation considering green vehicle routing problem   Order a copy of this article
    by Roohollah Ramezanzadeh Baraki, Farhad Kianfar 
    Abstract: In recent years, with the expansion of environmental issues and the consciousness raising of the customers, companies are experiencing huge pressure from shareholders and the government for greater compatibility with their environment. Companies and industry owners must implement green operations in their daily activities to be able to remain in the competitive atmosphere of the environment. One of the most important operations is cooperating with green suppliers. In this study, a multi-objective mathematical model is proposed to select suppliers and allocate optimal orders to them in a two-echelon supply chain, including supply and distribution echelons. The proposed model focuses on the routing of each supplier in addition to the selection of suppliers. Moreover, the possibility of storage, multi-product and multi-period state, and stair discount constitute the other assumptions of this model. Finally, the proposed model was implemented in a food distribution chain in Iran to validate it. The obtained results suggest the efficiency and effectiveness of the proposed model

  • A Systems Approach to Mapping Logistics Systems Performance of Small and Medium Manufacturing Enterprises   Order a copy of this article
    by Hemamala Krishnan, Sanjay Banerji, Mridula Sahay 
    Abstract: Logistics systems are complex networks of facilities that are designed to deliver products / services to customers with the objective of providing superior customer service in a most efficient manner. Measuring the performance of these systems is challenging owing to their structural complexity. Logistics facilities in the system are non-linearly interconnected with material, information and money flows causing response delays in the system. Measuring the performance of logistics systems therefore, requires a comprehensive understanding of the structure and behaviour of these systems. This paper proposes a systems approach to understand the structure of logistics system of small and medium manufacturing firms. A causal loop (Influence) diagram is proposed for mapping the system that identifies various key components of a logistics system - resources, performance drivers and outcomes and explains their interrelationships using feedback loops. The diagram explains the structure of the system that causes the observed system behaviour by describing how the deployment of logistics resources influences the outcomes through performance drivers.

  • The impact of the transport policies on marketing charges in the rail transport comparisons between the European Union member states   Order a copy of this article
    by Danica Murko, Zlatka Stok 
    Abstract: In recent years, the European Union devoted much attention to the transformation of a common rail market. This paper, therefore, focuses on intermodal rail transport in Slovenia. Subsidising intermodal rail transport in Slovenia between Austria and German is a current practice. The European Commission has studied internalising external costs for several years. In our research, we have conducted a review of the situation in the field of marketing for the use of public rail infrastructure in Slovenia. We suggest that the price of rail infrastructure charges gradually increase so that the funds obtained from marketing charges in 2020 accounts for half of the funds needed for the purpose of maintaining existing public rail infrastructure. However, investments in the modernisation of rail infrastructure are also crucial. Modernisation is the only way to ensure the competitiveness of rail transport services in the future.

  • Land Transportation Assets Potential Future Trends and the Third Party Logistics Providers in Emerging Markets, with a Case Study Applied in Brazil   Order a copy of this article
    by Douglas Tacla, Rui Botter 
    Abstract: This paper looks at Third Party Logistics (3PL) asset strategy options for land transportation in emerging markets through a case study of truck operations in Brazil. The fundamental question to be answered is: What is the preferred business model for a third party logistics (3PL) provider in emerging markets regarding asset ownership? That is, is it preferable for the 3PL to own and operate trucks? An opinion survey was deployed and analysed using statistical methods in association with market trend and financial aspects, interpreting the data in line with concepts identified through a literature review concerning the theme. This study is motivated by the challenges and decisions that the 3PL faces nowadays: whether to act as an integrator, managing and/or owing assets; or develop a business as a Leader Logistic Provider (LLP) managing third parties and/or outsourcing services. Moreover, global companies must integrate their business model in emerging markets with their global strategy. The results indicate that asset ownership may be a good strategy to access specific niches or enter a particular market, but this is not the current tendency of the logistics industry in emerging markets.

  • Influence of stock shortage in integrated logistic systems : an under-estimated importance   Order a copy of this article
    by Raymond Marie 
    Abstract: When evaluating performance of flow systems with such indicators as ``throughput'' or ``response time'', it is known that random delays with high dispersions degrade significantly the performances of the systems. Here we focus on the particular case of stock shortages in integrated logistic systems. These stock shortages create random delays on the component delivery and so they are the sources of disorders in the behaviour of the systems they impact. In this paper, we study the squared c\oe fficient of variation of the random variable which is a pertinent metric for evaluating the risk on the performances of the flow systems involved by the dispersion of the variable. After elaborating a realistic random model of an inventory, we present a way to exhibit the squared c\oe fficient of variation of the duration of the stock shortages. In the following part, we consider the random variable corresponding to the potential waiting times of all the orders which, for well tuned systems, has a relatively high probability to take the value zero. We show that the distribution of this latter variable admits a squared c\oe fficient of variation much higher than the former one. We also exhibit a few numerical examples in order to raise the reader awareness of the risk of under-estimating the importance of the stock shortages in integrated logistic systems.

  • Triple-Objective Models for Portfolio Optimization with Symmetric and Percentile Risk Measures   Order a copy of this article
    by Bartosz Sawik 
    Abstract: The purpose of this paper is to compare three di erent triple- criteria portfolio optimization models. The rst model is constructed with the use of percentile risk measure Value-at-Risk and solved by mixed integer programming. The second one is constructed with the use of percentile risk measure Conditional Value-at-Risk and solved by linear programming. The third one is constructed with the use of a symmetric measure of risk - variance of return - as in the Markowitz portfolio and solved by quadratic programming. Cardinality constraints are formulated in all models that limit the number of assets selected in the portfolio. Computational experiments are conducted for triple-criteria portfolio stock exchange investments. The results obtained prove, that the triple-objective portfolio optimization models with Value-at-Risk and Conditional Value-at-Risk could be used to shape the distribution of portfolio returns. The decision maker can assess the value of portfolio return, the risk level and number of assets choosen in the portfolio, and can decide how to invest in a real life situation comparing with ideal (optimal) portfolio solutions. The proposed scenario-based portfolio optimization problems under uncertainty, formulated as a triple-objective linear, mixed integer or quadratic program are solved using commercially available software (AMPL/CPLEX) for mathematical programming.

    Abstract: The operation of a transportation system is a factor of development for any region. However, the benefits provided are often accompanied by negative impacts on the environment, especially if the afore-mentioned operation is inadequately planned and controlled. This being so, the objective of this work is to present a procedure for obtaining an index representing the environmental performance of a cargo transportation mode as an instrument for guiding the decision-making process with regard to the choice of a sustainable mode for cargo transportation. The proposed index will be derived from the integration of several indicators related to different environmental aspects that could be damaged by the different activities performed. This integration will be achieved using fuzzy logic and neurofuzzy architecture. This index will assist enterprises when they are planning a sustainable cargo transportation service, environmental agencies in controlling such a service and society by preserving the environment and ensuring quality of life.

    Abstract: Stochastic timed Petri nets are among the most effective languages to model event driven uncertain processes. Their adoption in the industrial sector is even more diffuse and of potential help for the practitioners. This paper presents a stepwise approach to support the dynamic design and simulation of manufacturing and assembly production processes. An industrial application from the white good sector, based on a semi-automatic assembly line is, further, discussed demonstrating the approach flexibility and the modelling language key strengths. The stochastic timed Petri net model for such a scenario is described together with the simulation outcomes of interest for the assembly line design and the production and maintenance activity scheduling.

  • The strategic relevance of logistics: new perspectives   Order a copy of this article
    by Wanja Wellbrock, Ingrid Göpfert, Michael Stephan, Malte Ackermann 
    Abstract: We measure the strategic relevance of logistics in multinational corporations (MNCs) using two proxies: (1) the communication of logistics endeavors in annual reports and (2) the employment of logistics competencies on the top management level. We define logistics competencies as the employment of executive board members whoare assigned to logistics tasks. We examine 360 MNCs and their annual reports of the years 2000, 2004, and 2008 using content analysis. We show that there are considerable differences in the communication efforts amongst the geographical regions and the associated industries using the standard industrial classification (SIC) scheme. We present evidence that corporations originating in Asia are more likely to employ logistics competencies at the top level than their North American and European counterparts. On the other hand, Asian corporations are much more taciturn in their corporate disclosure policy. On an industrial level the transportation and chemicals subsectors are more likely to employ logistics competencies on their executive boards than other subsectors. Additionally, using partial point-biserial correlations. We demonstrate that the employment of logistics competencies is related to higher financial performance, further substantiating the strategic relevance of logistics for MNCs.

    Abstract: Our case study analyses the performance of 24 operating departments in Soroka Hospital in Beer-Sheva, Israel. Data Envelopment Analysis (DEA) was used with 5 inputs and 3 outputs over two years. These inputs and outputs reflected mostly logistic parameters and income of operating rooms. In the three operating sites investigated we found no significant difference in efficiency. We found that simple room utilization ratio is not sufficient for measuring efficiency. As a by-product of DEA, benchmark analysis verified inputs and outputs which need improvements in order to reach full efficiency, relative to their peers.

    Abstract: From an operations perspective, retailers are seeking to manage and improve relationships with their customers, brand image, customer services, etc. in order to underline their green potential, because literature has considered green and sustainable business practices as a means to reducing costs. Among different retail operations and activities, transport and logistics have caused the highest costs and have been insufficiently investigated as well. The main purpose of this paper is to investigate the greening of the transport activities in the food retail supply chain and characteristics of the food retailers` who are leaders in pursuing such activities. In such a way, the paper reveals the impact of food retailers` green initiatives on the way they manage their transport and logistics services. For the purpose of the paper, a quantitative study on the sample of 190 food retail companies operating on the Croatian market was conducted. The results suggest that generally retailers see green transport and logistics activities as an overall positive activity in terms of reducing costs and beyond, however usage of such green practices still differs a lot among observed food retailers.
