  • 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.

  • ENHANCING THE COMPETITIVE ADVANTAGES OF VIETNAMESE COFFEE THROUGH THE EXPLORATION OF CAUSAL LOOP MODELLING IN THE SUPPLY CHAIN   Order a copy of this article
    by Thich V. Nguyen, Nam C. Nguyen, Ockie J. H. Bosch 
    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.

  • Integrating Sustainable Development, Lean, and Logistics Concepts into a Lean Sustainable Logistics Model   Order a copy of this article
    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.

  • Material Flow Optimization in a Multi-Echelon and Multi-Product Supply Chain   Order a copy of this article
    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.

  • Role of management capability and Web-enabled direct procurement in creating competitive direct procurement advantage   Order a copy of this article
    by YI MING TAI 
    Abstract: Developing appropriate management capability enables manufacturing firms to strengthen competitive direct procurement advantage. The purpose of this study is to investigate what management capabilities can enable firms to create competitive direct procurement advantage and how Web-enabled direct procurement moderates the competitive impact of management capabilities. This study conducted an empirical survey with a valid sample of 101 manufacturing companies in Taiwan to evaluate the research model of this study. The results revealed that process management, trust-building, and coordination capabilities significantly influence the competitive direct procurement advantage. Moreover, this study observed that Web-enabled direct procurement alone does not directly influence the competitive direct procurement advantage. Web-enabled direct procurement plays a complementary role in reinforcing the effect of management capabilities.

  • 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.

  • City Logistics: Problems and Recovery Proposals   Order a copy of this article
    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.

  • PLANNING THE REVERSE LOGISTIC FOR RECYCLABLE SOLID WASTE BY A MATHEMATICAL MODEL AND A SIMULATED ANNEALING METAHEURISTIC   Order a copy of this article
    by Israel Gomes, Rodrigo Rosa, Carla Musso, Lucas Cinelli, Vitor Oliveira, Dahlen Silva 
    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.

  • Developing a Coordination framework for pharmaceutical supply chain: using analytical hierarchy process   Order a copy of this article
    by Gholamhossein Mehralian, Asieh Moosivand 
    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.

  • The Influence of Environmental Attitude on Consumers Intentions To Participate in a Take Back Program   Order a copy of this article
    by Siti Mahsanah Budijati, Subagyo , Muhammad Arif Wibisono, Nur Aini Masruroh 
    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.

  • MATHEMATICAL MODEL FOR PLANNING THE LAYOUT AND STACKING OF GRANITE BLOCKS IN A MARITIME TERMINAL   Order a copy of this article
    by Rodrigo Rosa, Eliane Gerzelj, Karina Fraga, Bianca Arpini, Dahlen Silva 
    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.

  • Multi Period Disassembly to Order of End of Life Product based on scheduling to maximize the Profit in Reverse Logistic Operation   Order a copy of this article
    by Sathish T , J Jaya Prakash 
    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. In the proposed structure artificial bee colony (ABC) algorithm is utilized. The proposed framework drives the preferred performance over the existing scheduling algorithms.

  • A COLLABORATIVE SUPPLY CHAIN MODEL FOR NON-FOR-PROFIT NETWORKS BASED ON COOPERATIVE GAME THEORY   Order a copy of this article
    by Vladimir Balza-Franco, Carlos D. Paternina-Arboleda, Víctor Cantillo, Luis Fernando Macea, Diana G. Ramírez-Ríos 
    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.

  • THE EVALUATION OF PORT GOVERNANCE ACTIONS BY PORT USERS PERSPECTIVE: A STUDY IN THE PORT OF SANTOS, BRAZIL   Order a copy of this article
    by Guilherme Bergmann Borges Vieira, Jonas Mendes Constante, Ricardo Dutra Scarpellini Silveira 
    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.

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.

    by Martin Dome, Sadananda Prusty 
    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.

  • Barriers Analysis for Green Supply Chain Management Implementation in Power Industry using ISM   Order a copy of this article
    by Sheetal Soda 
    Abstract: As industrial development spills over to developing nations spiralling global energy demand, there is increased concern for environment as power generation is closely associated with environmental degradation and pollution. In contrast to developed nations, the developing nations are relatively lagging when it comes to greening supply chain of power industry. India is fast emerging as a prime energy producer, as well as consumer of energy. The Indian Power industry is witnessing a phase of transition, wherein switchover from traditional operations to modern practices is precipitating; but still there is a long way to go. With sustainable development becoming a buzz word in socio-economic settings the world over, the call for cleaner energy is gaining louder, day by day. At the forefront of the targeted industries blamed for pollution and environmental degradation, lies the Global Power Industry. The answer lies in the adoption of Green Supply Chain Management (GSCM) techniques to various sections of the industry. This research study aims to evaluate prominent barriers and their interrelations in retarding the spread of GSCM culture. The power industry of Punjab (India) has been considered for the study, with the intent to assess the environmental consciousness imbibed and exhibited by its constituent companies in their infrastructural setup and operational undertakings. This research paper makes an attempt to assess the barriers that were identified from extensive literature review and opinions invited from power industry-experts that impede implementation of GSCM by making use of Interpretive Structural Modeling (ISM).A hierarchy-based model was presented with the application of ISM Techniques to identify contextual relationships among the sixteen identified barriers that offer prospects for constructing greener models of Power Industrys Supply Chain. Out of sixteen barriers, Insufficient Government Support and Limited Investment in Green Measures barriers are found to be significant, which invoke unfavorable response from the government. These barriers act as major hindrances in a spread of GSCM across the organization. To enhance the validity of the results so reached, opinions of different industry experts were invited to corroborate the earlier deductions; thereby yielding a more accurate model. This has added to the credibility of the findings.

  • A hybrid approach based on BOCR and fuzzy MULTIMOORA for logistics service provider selection   Order a copy of this article
    by Anjali Awasthi 
    Abstract: Partner selection is critical to developing successful collaboration for gaining competitive advantage in logistics industry. In this paper, we present a hybrid approach based on BOCR and MULTIMOORA for logistics service provider selection. The proposed approach comprises of three steps. In the first step, we identify the partner selection criteria using four categories namely Benefits, Costs, Opportunities and Risks (BOCR). The second step involves generating linguistic ratings for potential partners on the identified criteria by a committee of decision making experts. In the third and the last step, final partner selection is done using fuzzy MULTIMOORA. Linguistic information (fuzzy numbers) are used to address the lack of quantitative data. A numerical application is provided. Monte Carlo simulation-based sensitivity analysis is conducted to determine the robustness of MULTIMOORA to variation in criterion and decision maker weights.

  • Human Errors in Warehouse Operations: An Improvement Model   Order a copy of this article
    by Parama Kartika Dewa, Nyoman Pujawan, Iwan Vanany 
    Abstract: Warehouse operations are very much dependent on manual works and hence, humans play critical roles. In order to have an excellent warehouse performance, it is imperative to address the human needs so that the errors can be minimized. Papers addressing human factors in warehouse operations are limited. The purpose of this paper is to develop an improvement model that can connect between warehouse performance, human errors in the process, and actions needed to improve the performance. We propose a two-stage deployment procedure, modified from the well-known Quality Function Deployment (QFD). The first stage is to screen human errors that substantially affect warehouse performance. The second stage is to prioritize proposed improvement actions that could address most effectively the human errors. The model is applied to a warehouse operated by a logistics company that handles the storage and distribution of fast moving consumer goods.

    by Dmitriy S. Rybakov 
    Abstract: The purpose of this research is to develop a model for optimising total logistics costs of a trading company. To achieve the aim, a logistics system has been analysed and, as a result, major subsystems, logistics processes and most substantial logistics costs have been identified. The results of the analysis have been used to elaborate conceptual and structural optimisation models. They have been further used to develop a mathematical model considering both direct and indirect costs. The mathematical model has been tested numerically, so a table model has been worked out. The research has resulted in a Boolean linear programming model for determining the values of the indicators of the order cycle time and stock level, ensuring optimal total logistics costs of a trading company. Strategic objectives have been decomposed into the goals of individual departments, expressed with the target values of the indicators of lead time and cargo turnover.

    Abstract: Rice is the major staple food of Odisha. Almost 70% of the population of the state depending upon agriculture and out of which the major produced crop is rice. Odisha stood 5th in rice production in India. The impact of techno-environmental uncertainty factors like logistical problems, product specification, opportunistic behavior, on time delivery, average lateness, degree of inconsistency, reduction in cost, on time governance mechanism, increase in knowledge flow between firms and climate change on agricultural ecosystems have been a matter of concern for food security in the present situation. The uncertainty factors that are likely to enhance considerably the climate risk to the major agricultural ecosystems are: increase in temperature, higher carbon dioxide concentrations and abnormal pattern of precipitations coupled with higher frequency, drought and floods. The intent of this study is to fill the gap by providing a framework addressing how to leverage uncertainty factors to improve supply chain performance in the Indian market. In this research, strategic supply management due to the uncertainty factors to rice based supply chain which supports the livelihood security for a very large number of poor and marginalize people in India have been reported. A statistical tool (Full factorial design methodology) has been introduced here to analyze and access qualitative as well as quantitative measures. Models for capturing various uncertainty factors have been developed and the impact of uncertainties on strategic supply management tested. The present work has efficiently demonstrated the different techno-environmental uncertainties and its significance in strategic decision making.

    by Kamal Mittal, Pramod Jain, Dinesh Kumar 
    Abstract: Reconfigurable manufacturing systems (RMS) is considered as a major resource of providing variable production capacities and capabilities by different manufacturing companies. For different products needed in small quantities and with short delivery lead time, this is achieved through reconfiguring the system elements over the time. There is a need to develop a suitable performance index for mapping the manufacturing system characteristics. To find the reconfigurability of RMS considering the different characteristics such as modularity, convertibility and diagnosability an index has been developed in this paper. Using weighted sum theory, these characteristics have been mapped together. A case study is given to understand the applicability of the proposed methodology on a given system.

  • FMEA Based Interpretive Structural Modelling Approach to Model Automotive Supply Chain Risk   Order a copy of this article
    by Ajay Kumar Pandey, Rajiv kumar Sharma 
    Abstract: The purpose of this study is to analyse and model various risks which may disrupt the automotive supply chain. For illustration, an automotive supply chain of tractor manufacturing company has been undertaken, seventeen potential modes of failures or risk sources are identified through close scrutiny of literature and weighted risk priority numbers (WRPN) have been calculated. Out of these seventeen failure modes, eleven are selected as key learnings (by performing SAP-LAP analysis) based upon higher WRPN numbers. Further to model, the structural relationship among these key risks Interpretive Structural Modelling (ISM) approach is used. In order to find out the driving power and dependency of risks MICMAC analysis has been performed. The results of the study demonstrate that the variables i.e. poor planning and scheduling and hazards are the key risk variables (highest driving power) and can be considered as the root cause of the problem. Quality risk, inventory risk and outsourcing risk have strong dependence power and hence can be considered as the most important risks and management shall focus on these for the managing the disruptions in an automotive supply chain.

  • Inventory model with expiration date of items and deterioration under two-level trade credit and preservation technology investment for time and price sensitive demand: DCF approach   Order a copy of this article
    by Nita Shah, Urmila Chaudhari, Mrudul Jani 
    Abstract: In this cut-throat competitive business world, cash-on-delivery is no longer a practice. Consequently, the retailer offers numerous short-term or long term credit limit to the customer. The middle-layered player passes the offer of delay payment to the end users. In addition, most of the items have a fixed lifetime and deteriorate continuously which cannot be sold after its expired dates. However, preservation technology investment can reduce deterioration rate of items in retailers inventory system. In this paper, an inventory model is formulated when retailer offers partial credit which he received from the supplier when demand is decreasing with time and price. The profit function is constructed using inflation rate and risk involved due to offer of credit period in generating revenue. The decision policies are analyzed for the decision maker. Numerical examples are used to demonstrate the theoretical derivations. Sensitivity analysis is carried out for the advantageous scenario depending upon the lengths of the credit periods.

    by Roberta Scarsi, Riccardo Spinelli 
    Abstract: Third-party logistics is a very heterogeneous industry, moving towards a progressive concentration and services differentiation at the top, but still made up by companies that differ in terms of size, supplied services, and background. This structural variety offers the starting point for a grouping analysis, which aims to identify strategic groups among major players in the industry. 199 third-party logistics service providers (3PLs) worldwide are analysed applying a two-step clustering technique to a wide set of variables which refer to the main strategic drivers for 3PLs. Three strategic groups emerge from the analysis. The first one includes major global players; the second one encompasses less advanced local providers; the third one embraces a large number of firms which are experiencing a transition from simple to more complex and internationally oriented business models.

    by Surya Prakash, Gunjan Soni, Ajay Pal Singh Rathore 
    Abstract: Present day supply chains are dynamically expanding with the increase in globalization but susceptible towards a number of risks too. The risks cause disturbances in supply chain and hinder the movement of products across their stage which ultimately leads to overall increases in supply chain costs. In this paper, a multi-echelon closed-loop supply chain model is considered, where suppliers quality risks (production issues), logistics risks (transportation issues) are mathematically modeled using mixed integer linear programming (MILP) formulation. The paper highlights benefits of adopting the supply chain network design under risk. The comparison of risk and no risk situation is illustrated for a generic closed-loop supply chain network. The findings suggest that risk consideration in supply chain network design is very useful, and its cost is not much higher to the organization too. The supply chain resilience can be achieved with a moderate risk premium. The firms which can pay 10-13% more will be able to sustain in risk events and their network configuration will be robust under supply and logistics risks happenings.

    by Abhijit Baidya 
    Abstract: Transportation policy seeks to improve agency freight and cargo management and enhance sustainable, efficient and effective transportation operations. In this paper, four new fuzzy fixed charge solid transportation problems (FFCSTP) are formulated to maximization the total profit and minimization the total cost of the retailer at the destinations with imprecise values of unit transportation cost (UTC), purchasing cost (PC), selling price (SP), resources, demands, conveyances capacities. Three new constraints (interval-valued weight, volume and budget constraint) are also investigated to formulate the interval-valued solid transportation models. The fuzzy quantities are converted to interval numbers using nearest interval approximation. The interval objective function is approximated by an interval-valued function i.e., transformed to a single objective using weighted sum method and weighted multiplication method. The fuzzy constraints are converted to its equivalent deterministic form using different interval order relations. GA and PSO algorithm are used to obtain the optimal transportation schedule for the proposed solid transportation problem. To validate the results, five equivalent forms of the four proposed models are obtained by using different interval approaches and order relations. During the evaluation of the models, in one case, limitation on the transported amounts is imposed and in other case, no such limitation is used. The models are illustrated with numerical examples and the optimum results of the models are compared.

  • Configuration and implementation of a daily artificial neural network based forecasting system using real supermarket data   Order a copy of this article
    by Ilham Slimani, Ilhame El Farissi, Said Achchab 
    Abstract: The purpose of any effective supply chain is to find a balance between supply and demand by coordinating all internal and external processes in order to ensure delivery of the right product, to the right customer, at the best time and with the optimal cost. Therefore, the estimation of future demand is one of the crucial tasks for any organization of the supply chain system who has to make the correct decision in the appropriate time to enhance its commercial competitiveness. In an earlier study, where various artificial neural networks structures are compared including Perceptron, Adaline, No-Propagation, Multi Layer Perceptron and Radial Basis Function for demand forecasting, the results indicate that the Multi Layer Perceptron (MLP) structure of neural network present the best forecasts with the optimal Absolute Error, Mean Squared Error and the lowest Mean Absolute Percent Error. Consequently, the major aim of this paper consists on modeling and implementing a daily demand predicting system using the MLP architecture to forecast future demand of a Moroccan supermarket based not only on historical data, but also with the addition of other inputs and parameters such as previous demand quantities, days classification and average demand quantities. The results are satisfactory and promising, because adding these new inputs to the adopted neural network has a positive impact on the accuracy of short-term demand forecasting manifested in an optimum error. Besides, the accuracy of demand forecasts in a supply chain is a key element of competitiveness and since the results are validated using real dataset, the proposed forecasting model can be implemented as a solution to demand uncertainty in any real supply chain.

    Abstract: The present paper focuses on an EOQ (Economic Order Quantity) inventory model for deteriorating items having stock dependent demand when delay in payment is permissible. The deteriorating items follow constant deterioration rate. Shortages are allowed and are completely backlogged. The mathematical models are also derived under two circumstances: Case I: The permissible delay period is less than or equal to the shortage time point for settling the account and Case II: The permissible delay period is greater than the shortage time point for settling the account. Numerical examples are provided to illustrate the effectiveness of the proposed methods and solution procedure. Furthermore, sensitivity analysis of the various parameters is carried out and some interesting managerial insights are presented.

    by Marcelo Barbosa, Jonathan Freitas, Marcelo Ladeira 
    Abstract: The historical strong emphasis on quantitative studies in Supply Chain Management (SCM) is giving place to more qualitative studies. The execution of SCM activities as well as interactions among participants in the chains generates lots of information which can be analysed using qualitative methods. A common methodological problem in such analyses is how to move beyond specific linguistic material to generalizations. One method suited for this is Centering Resonance Analysis (CRA), which allows the synthesis of texts into smaller categories. This article discusses the contributions and potential future use of CRA in SCM field by performing a systematic literature review in studies that adopted this technique. Results showed that CRA has been adopted in SCM since 2010 in order to analyse documents that vary from training materials and corporate social reports to interviews and software documentation. A characterization of methods applied in conjunction with CRA is also provided.

    by Navee Chiadamrong, Tran Thi Tham 
    Abstract: This study proposes an integrated approach to determine the most suitable strategies, based on Structural Equation Modeling (SEM), Fuzzy-QFD, and Multi-Objective Linear Programming model (MLP). The relationships between supply chain capabilities, competitive advantages, and business performance are identified using SEM. An integrated SEM and Fuzzy-QFD approach is proposed to transform the significant factors into SCM strategies. Then, MLP model is applied to identify suitable strategic actions according to multiple conflicting objectives under a budget constraint. A case study from the Vietnamese food industry is given to illustrate the proposed methodology. The outcome of the study reveals that companies should pay more attention to supply chain capabilities for SCM strategy development, which can help to gain improvement of their competitiveness and business performance. The proposed methodology also provides a comprehensive picture for companies by transforming such relationships into specific SCM strategic actions to obtain the optimal solution according to their preference.

  • Adaptation of simulated annealing to an integrated municipal solid waste location-routing problem   Order a copy of this article
    by Hossein Asefi, Samsung Lim, Mojtaba Maghrebi 
    Abstract: Waste management and its associated processes and activities are one of the challenging issues for municipalities and other responsible sectors in most mega cities. Due to the population growth and technological progresses nowadays, the amount of waste generation in different types (e.g. recyclables and hazardous wastes) has increased significantly. Municipal solid waste management involves the collection, transportation, recycling, treatment and disposal of different types of wastes. Among the associated costs in municipal solid waste management, the transportation cost as one of the most significant constraints can be effectively economized by efficient planning approaches. This paper aims to present an integrated municipal solid waste management network covering multiple types of wastes concurrently and utilize the location-routing problem framework to minimize the establishment cost of the interrelated facilities (i.e. transfer stations; treatment, recycling and disposal centers) in the network and the transportation cost of wastes in the entire network. The defined problem consists of the concurrent site selection of the locations of the systems all facilities among the candidate locations and the determination of routes and amounts of shipments among the selected facilities to minimize the total cost of transportation and facility establishment. As the addressed problem exhibits the non-deterministic polynomial-time hardness (NP-hardness), an adaptation of the simulated annealing algorithm is proposed in this paper to solve the problem. The obtained results compared against the exact solutions by mixed-integer programming in terms of solution fitness and computing time imply that the employed algorithm works effectively and efficiently.

  • Supply Chain Analytics for Enhancing the Maritime Security   Order a copy of this article
    by Hokey Min, Yong-Kon Lim, Jong-Won Park 
    Abstract: Seaports across the world can be a frequent target for illegal activities such as contraband, weapon smuggling, drug trafficking, human trafficking, piracy, and terrorist attacks. Despite the increasing risk of those illegal activities, many ports are not equipped to deal with unforeseen security breaches. Although the use of X-ray scanning technology for cargo inspection has been on the rise due to its effectiveness in detecting potential security breaches, it alone cannot protect the port and its surrounding areas from illegal activities. To maximize the full benefit of X-ray based cargo inspection through enhanced maritime logistics visibility, we propose supply chain analytics which can not only add business intelligence to the cargo inspection process, but also guide the port authority to make informed decisions regarding security protocols. This decision-aid tool is designed to improve port security and productivity by systematically gathering, storing, analyzing, and updating big data related to cargo movement, port infrastructure, and ocean-going vessel traffic. This paper is one of the first to embed supply chain analytics within the maritime security system and gauge its usefulness for enhancing maritime security in global supply chain operations.

    Abstract: In this study, we present an analytical framework for supply chain disruptions planning of a multi-agent, multi -product supply chain with an emphasis on Conditional Value at Risk (CVaR) as a risk measure. In a risk-neutral operating condition, the decision maker seeks to minimize the expected cost. On the contrary, a risk-averse decision maker wants to minimize the expected worst-case cost of a system of interest. Considering the significance of the risk of higher cost in supply chain planning and management, this paper makes an attempt for the minimization of expected worst case cost as a CVaR measure. At the same time, the CVaR model targets to compute the response policies of a supply chain system that undergoes supply and demand disruptions. The proposed formulation is illustrated through some numerical examples. In addition, some computational results are also reported to demonstrate the benefits and applicability of the model in supply chain disruptions planning and decision-making process. The results present that the CVaR model shows a considerable difference in response policies in comparing with the expected cost model. Ordering quantities in response to supply and demand disruption are lower in the CVaR model than the expected cost model. In many instances, it is also seen that ordering quantities in response to disruptions tend to become lower when a decision maker becomes more risk-averse. It is expected that the proposed CVaR model would outperform to optimize the supply chain of an organization, in particular, for the purpose of reducing the risk of high cost.

    by Aparna Choudhary, Sandeep Mondal, Kampan Mukherjee 
    Abstract: Increasing concern towards environment has forced the manufacturing firms to adopt green supply chain practice (GSCP) in their business processes. Managing these practices efficiently is a major challenge facing by manufacturing firms. Purpose of this paper is to explore the critical factors for managing green supply chain practice in small and medium enterprises (SMEs), and establish contextual relationship among them. A tentative list of 29 constructs influencing the management of GSCP was identified through extensive literature review and discussion with a panel of experts. A questionnaire was developed and survey was conducted on 162 SMEs. Applying factor analysis, constructs were summarized into eight critical factors. Interpretive structural modeling (ISM) methodology was deployed to develop a structural model of these factors. Considering the outcome of ISM as an input, MICMAC (Matrices Impacts Cruises-Multiplication Appliqu

  • Multi-objective evolutionary algorithm for a ship routing problem in maritime logistics collaboration   Order a copy of this article
    by Eric Wibisono, Phongchai Jittamai 
    Abstract: This paper proposes a multi-objective evolutionary algorithm in maritime logistics collaboration of two liner shipping companies in joint-routing network design. The model is called the ship routing problem and two objectives being minimised are total cost and deviation in fair cost proportion. The method combines NSGA-II and the principles of effective genetic algorithms from the literature, and an example of application with data background from the Indonesian archipelago is demonstrated. Both the method and its application in real-life problems have never been encountered in academic publication, therefore this research has significant contribution and practical values on those fronts. Three dispersal mechanisms are tested with two different mutation probabilities and the results suggest that different rate supports different mechanism. Running times are longer in higher mutation rate, but in general the DV(1) mechanism is faster than both DL mechanisms. Non-dominated solutions are found and translated to joint routings of both carriers.

  • Control Aspects in Humanitarian Logistics   Order a copy of this article
    by Thomas E. Fernandez, Nanthi Suthikarnnarunai 
    Abstract: In this paper, the authors look at the control aspects of three types of organisations involved in Humanitarian Logistics: Humanitarian Relief Organisations (HROs), commercial companies, and military organisations. Looking at both internal and external control mechanisms, this paper explores the suitability of each type of organisation in the three phases of disaster, namely preparedness, emergency response and recovery. They find that, looking at the control aspects alone, both commercial companies and HROs are well suited for logistics in the preparedness phase, while the HROs are best suited in the emergency response phase. In the recovery phase, commercial companies are best suited.

  • A robust replenishment model for deteriorating items considering ramp-type demand and inflation under fuzzy environment   Order a copy of this article
    by Archana Sharma, Usha Sharma, Chaman Singh 
    Abstract: Supply chain performance directly depends on demand pattern, inventory management and control strategies of organizations apart from other supply chain activities. Effective replenishment policy can increase the performance of logistics and supply chain activities and customer satisfaction. Optimal inventory model can also reduce overall replenishment cost and improve financial performance of the organization. This study focuses on developing a replenishment model for deteriorating products with ramp-type demand rate under the consideration of inflation and partial backlogging. The nature of the demand function is a piecewise exponential function. The proposed model is developed under fuzzy environment, which can easily handle uncertainty and impreciseness associated with parameters. The illustrative numerical example has given in crisp as well as in fuzzy sense to demonstrate the solution procedure for the proposed approach. Sensitivity analysis is also performed to check robustness of the proposed model.

    by Fatemeh Ranjbar Tezenji, Mohammad Mohammadi, Seyed Hamid Reza Pasandideh 
    Abstract: this paper proposes a bi-objective integrated model for supplier location-allocation, capacity allocation and supplier selection and order allocation problems in a two echelon supply chain. The goals of the proposed model is to (i) select the best supplier(s), (ii) locate the selected supplier(s) in the best location(s), (iii) determine the optimal capacity of selected supplier(s), (iv) allocate the customer(s) to supplier(s), and (v) allocate customers order (order interval). In the first step we proposed a single-objective model to minimize the total costs consist of inventory related costs (purchasing, inventory replenishment, holding and shortage (backordering) costs), transportation costs (fixed and variable costs) and fixed establishment costs. In the second stage we used de novo programming to determine the optimal capacity of selected supplier(s). Therefore, we consider a second objective function to minimize the total costs related to capacity of selected supplier(s) (variable establishment cost). We used NRGA and NSGA-II algorithms to solve the proposed bi-objective mix-integer non-linear model. At the end, we propose various test problems to show the performance of the proposed methodology. To show which meta-heuristic algorithm is better we used t-test and the simple additive weighting (SAW) method.

  • Effective Governance Defines Strategic Supply Chain Outsourcing Success in India   Order a copy of this article
    by Vijayakumar Sangam, Himanshu Shee 
    Abstract: This paper aims to study whether effective governance can have a positive influence on the success of supply chain outsourcing. While earlier studies mostly focused on key success factors of logistics outsourcing, the importance and effect of governance on logistics outsourcing success merits further investigation. Governance in joint participation, mutual conflict resolution and collaborative relationships are conceptualized as antecedents of outsourcing success. The results of SEM analysis of survey data from 297 professionals representing shipper organizations in India revealed a positive and significant relationship between dimensions of governance and outsourcing success. The findings draw shippers attention to collaborative relationship governance at early conceptual stage; joint work on risk and reward sharing at implementation stage; and mutual conflict resolution at post-implementation stage in order to achieving outsourcing success in India.

  • An inventory model for deteriorating item with frequency of advertisement and selling price dependent demand under mixed type trade credit policy   Order a copy of this article
    by Ali Akbar Shaikh 
    Abstract: In this paper, we have developed an inventory models for deteriorating items with selling price and frequency of advertisement dependent demand of an items under the mixed type financial trade credit policy. Shortages are allowed and partially backlogged with a variable rate dependent on the duration of waiting time up to the arrival of next lot. In this model, the deterioration rate follows three-parameter weibull distribution. Transportation cost is dependent on the lot-size as well as the distance from the source to the destination. The corresponding model have been formulated and solved by generalized reduced gradient based method. Numerical examples have been considered to discuss the results and the significant features of this model. Finally, based on these examples, the effects of different parameters have been studied by sensitivity analyses taking one parameter at a time keeping the other parameters as same.

  • PLANNING THE BERTH ALLOCATION PROBLEM IN DEVELOPING COUNTRIES WITH MULTIPLE CARGOS AND CARGO PRIORITY BY A MATHEMATICAL MODEL AND A CLUSTERING SEARCH METAHEURISTIC   Order a copy of this article
    by Rodrigo Rosa, Glaydston Mattos, Geraldo Mauri, Winnie Fracaroli 
    Abstract: Some Brazilian ports operate several different cargos. These ports were privatized, and to avoid the private companies to restrict their operations to some few profitable cargos, the Brazilian government established rules, called cargo priorities, to ensure that all cargos are handled at the ports. These rules have a direct impact on port operations, especially when it comes to define the allocation of berth space for vessels. Thus, this paper presents a mathematical model and a Clustering Search (CS) metaheuristic for the berth allocation problem with multiple cargos and cargo priorities, considering time and space constraints. The paper is motivated by a port terminal located in Brazil, which handles containers, granites and cars. CS solved both instances based on real data and instances created to test large problems. An extensive analysis of all the results is also presented.

  • An evolutionary approach for supply chain management   Order a copy of this article
    by Xiaoming Li 
    Abstract: This paper aims to provide a simple pragmatic approach for supply chain management, departing from the current mainstream chase on supply chain integration. We first summarize two dominant but opposite approaches, the decentralized traditional approach and the centralized supply chain management approach, each of which has its distinct strengths and obvious weaknesses. To take advantage of their strengths and overcome their weaknesses, an evolutionary approach is laid out by applying key insights of the Theory of Evolution self-interest, adaptation, and natural cooperation, and of supply chain management demand and supply evolution. We propose an evolutionary approach that integrates four rudimentary advantages: the organization fulfills its own interest, the organization is better adapted to its local environment, natural cooperation is built on direct reciprocity, and demand and supply evolution provides a differential preservation of interrelations between suppliers and buyers. A two-stage newsvendor game illustrates its practical implication, which confirms the evolutionary approach is a legitimate alternative to the current systems integration approach for supply chain management.

  • Using VMI to Improve Supply Chain Performance of a Public Enterprise in Thailand   Order a copy of this article
    by Thananya Wasusri, Buntita Pongcheep 
    Abstract: Supply chain management is well recognized and implemented in private sectors, but the beneficial of supply chain management in public sector is limited shown in the literature. This paper presents a comprehensive supply chain simulation study for a real case of Thai public sector focusing on its material supply network. The supply network consists of four stages in inventory system: head office, regional warehouse, main warehouse and service warehouse. This study aims to propose three different strategies according to the combination of purchasing structure and Vendor Managed Inventory (VMI) with targeting to reduce lead time and cost. The Discrete event simulation (DES) is a powerful tool used to reveal the supply chain performances. The three strategies result in shorter lead time and cost reduction. The decentralized purchasing with VMI on each echelon to support continuous replenishment offers the best solution. The managerial implication is provided to enable the enterprise to improve the supply chain performance measures.

  • PLANNING THE DISTRIBUTION OF GOODS IN THE CONTEXT OF CITY LOGISTICS CONSIDERING SPLIT DELIVERIES WITH ACCESS AND TIME RESTRICTIONS   Order a copy of this article
    by Rodrigo Rosa, Renata Arantes, Henrique Astoures, Dahlen Silva 
    Abstract: Cities are getting bigger with more homes and companies which demands more goods to supply them. Furthermore, more vehicles are traveling in the cities which leads to an increase of greenhouse gas emissions, traffic jam and many other problems that damage the citizens quality of life. To make it better, local governments are imposing restrictions on the type of vehicles and the time that they can deliver goods in the city. Thus, to plan the distribution of goods in this restricted context, this paper proposes a mathematical model that incorporates the characteristics of split deliveries, heterogeneous fleet, access restrictions and time windows for planning the distribution of goods. Based on real data from an agricultural supply company that delivers goods to supermarkets, seven instances were elaborated and the results showed that the model can bring cost savings for the company and environmental benefits for the citizens.

    by Seyed Mahdi Aghazadeh, Mohammad Mohammadi, Bahman Naderi 
    Abstract: This paper proposes a new multi-objective model for organ transplant supply chain under uncertainty conditions. Previous models have focused on time, location and allocations separately, and have not considered some important aspects in locating healthcare units. Because of the vital role of these parameters in decision making about locating organ transplant supply chain, this new model compensates for and covers this shortcoming. These significant parameters include: 1. Expected number of organs donors. 2. Coverage rate of other zones for the selected locations based on cold ischemia time for each organ. (Cold ischemia time is the maximum time each organ can bear outside the body. 3. Safety index based on earthquakes and other natural or unnatural events. The model consists of three objective functions: the first objective function reduces the costs of the active working centers. transportations and allocations of units and organs, and the second objective function considers the mentioned parameters too. These objective functions are likely to face conflicts based on the input data. Finally, some statistics-based experiments have been conducted on the problem under study, and it has been solved using GAMS optimization software (ver. 23.5).

  • Nobody Wants to Buy Sour Milk: Supply Chain Performance Measure Matters   Order a copy of this article
    by Wei Wei, Jwen Fai Low, Andrea Schiffauerova 
    Abstract: In the increasingly competitive manufacturing landscape, the key to thriving is in managing the supply chain. Supply chain performance measurement systems, which gauge the performance of a supply chain on different metrics, are indispensable tools for supply chain management. By introducing a weighted and industry-independent performance measure and incorporating it in a questionnaire distributed to manufacturing companies, we were able to compare supply chain performance between different categories of manufacturers. We identified management as the biggest impediment towards implementation of supply chain performance measures. The results also show that supply chains in light industry are flexible but members of each supply chain interact poorly. Heavy industry supply chains suffer from inflexibility but have good interactions between members within each supply chain. Despite international supply chains having many advantages over domestic supply chains, our survey respondents indicated that global supply chains perform better than local supply chains. And, supply chains which have members who are actively cooperating, whether in the form of a pact, partnership, or alliance, perform better than supply chains where such cooperation does not exist. Finally, our study found that the performance of supply chains with performance measurement systems in place trumps the performance of supply chains without them.

    Abstract: The main aim of this study is to understand how buyer-supplier relationship and social capital influence green supply chain collaboration in manufacturing companies. Also, the mediating role of social capital between buyer-supplier relationship and green supply chain collaboration was examined. Because of that a sample of 70 from logistic and middle levels managers were chosen for distributing questionnaires. Collected data were analyzed by Partial Least Square method of structural equation modeling. The results indicated that there are positive relationships among buyer-supplier relationship (asset specificity, transaction frequency and competitive environment) social capital and green supply chain collaboration. Also the mediating role of social capital confirmed. But two hypotheses which are related to relation volume uncertainty with social capital and green supply chain collaboration are rejected. These findings provide considerable insights to managers and marketers of green supply chains that seek to respond to a growing interest of environmental performance of supply chain.

    by Farida Pulansari, Suparno Suparno, Sri Gunani Partiwi 
    Abstract: Reverse Logistic (RL) and management of unused product, waste as well as limitation of natural resources are growing problems throughout the decade. The RL has been successfully implemented in some companies, however, no clear key performance indicator or parameter of a successful RL is provided. The paper proposes a framework for assessing the maturity level of the RL implementation. The framework was designed in order to provide the information as well as a clear key performance indicator that are easy to learn and be applied. The procedure of assessing the framework was to come to many companies to measure the level of RL implementation. Better integration among supply chain actors (manufacturer, recycled center, collection center, supplier, disposal center, and distribution center), government and customer can minimize the environmental problems. The finding shows that the maturity level in the implementation of RL for the Indonesian consumer electronics industries is at level 2 (Managed Level), especially in the local companies.

    by Senthil Kumar 
    Abstract: In real-life decisions, usually we happen to suffer through different states of uncertainties. In order to counter these uncertainties, in this paper, the author formulated a transportation problem in which costs are triangular intuitionistic fuzzy numbers, supplies and demands are crisp numbers. In this paper, a simple method for solving type-2 intuitionistic fuzzy transportation problem (Type-2 IFTP) is proposed and optimal solution is obtained without using intuitionistic fuzzy modified distribution method and intuitionistic fuzzy zero point method. So, the proposed method gives the optimal solution directly. The solution procedure is illustrated with the help of three real life numerical examples. Defect of existing results proposed by Singh and Yadav (A new approach for solving intuitionistic fuzzy transportation problem of type-2, Annals of Operations Research (2014): 1-15.) is discussed. Validity of Pandians method (Realistic Method for Solving Fully Intuitionistic Fuzzy Transportation Problems, Applied Mathematical Sciences, 8 (113), 5633-5639.) is reviewed. Finally, the comparative study, results and discussion are given.

    Abstract: We consider the coordinated capacitated lot-sizing problem (CCLSP) with stochastic non-stationary demand. Although the CCLSP with deterministic demand and the uncoordinated CLSP (UCLSP) with stochastic demand have been addressed in the literature, there is no published research on the CCLSP with stochastic demand. Motivated by the case of Stokke, we develope the formulation and solution method for a special case of the CCLSP. Our model is tested in the settings of stochastic and deterministic demand. The stochastic model out-performed the deterministic model with significantly lower total cost, leading to a reduction in inventory costs and to a slight increase in use of emergency supplies.

    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, organisations 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.

  • Driving forces and interfaces between elements of triple bottom line - findings and propositions of TBL management   Order a copy of this article
    by Nils M. Høgevold, Göran Svensson 
    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 organisations, the marketplace and in the society beyond mere compliance. The results from 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 labelled TBL management. This is an attempt to emphasise 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 recognised 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 modelling and methodology, the basic newsvendor model specialises in the case of discrete probability distributions. The compound distribution generates scenarios that allow solving the stochastic optimisation problem of expected profit maximisation 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.

    by Vahid Mirzabeiki, Violeta Roso, Per Sjöholm 
    Abstract: The purpose of this paper is to analyse the benefits of the application of a radio frequency identification (RFID)-based collaborative tracking and tracing (CTT) system on a logistics setting in which freight is transported by rail between a seaport and a dry port. The case study research method was used for this study and the empirical data were gathered through a research project, which was carried out in Sweden. The results indicate that opportunities for improving the speed of operations, resource utilisation, timeliness of operations, safety of operations, and finally, improving the quality of data are created for multiple actors within the studied logistical setting after application of the CTT system.

  • Supply chain management and marketing integration: enhancing customer lifetime value   Order a copy of this article
    by Pankaj M. Madhani 
    Abstract: The supply chain management (SCM) and marketing integration has a direct and significant impact on customers and the revenue-earning potential of the firm. Hence, it is vital for the firm to achieve better synergy between them. SCM and marketing integration is a complex and multi-faceted construct and hence requires strategic approach for its evaluation. This study aims to understand how to achieve SCM and marketing integration by focusing its facilitators and controlling distracters. This research develops various frameworks and models for better understanding of SCM and marketing integration. This research demonstrates the benefits of a close integration between SCM and marketing and evaluates its impact on customer lifetime value (CLV). The contribution of this article is both theoretical and practical. From a theoretical perspective, the frameworks developed for study of SCM and marketing integration are an important contribution to the existing knowledge. From a practical perspective, various models of this paper aim at providing guidelines for SCM and marketing managers for building competitive advantages by achieving SCM and marketing integration.

  • Identification of critical success factors for green supply chain management implementation   Order a copy of this article
    by Rakesh Kumar Malviya, Ravi Kant, Ashim Dutta Gupta 
    Abstract: The objective of this study is to identify the critical success factors (CSFs) for successful green supply chain management (GSCM) implementation. The nationwide questionnaire survey and fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL) method is used to identify critical success factors (CSFs) for GSCM implementation. The total 35 influential factors were identified through literature review and expert discussion. Out of which 29 influencing factors (Mean ≥ 3.00) were selected through a nationwide survey of Indian automobile industries. The empirical case study of an Indian gear manufacturing organisation is presented to identify CSFs and to validate the applicability of the proposed framework. The proposed fuzzy DEMATEL method identified 12 CSFs from 29 influencing factors which will help to improve the effectiveness and efficiency of successful GSCM implementation. The findings help in understanding GSCM deeply which offers a meaningful base and provides an indication to build an effective phase-wise GSCM implementation.

  • 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 USA 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 US destination ports. Despite numerous benefits of using X-ray scanning technology, maritime industry sectors and port authorities still are hesitant to utilise 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.

  • Logistic service quality and organisational performance: conceptualisation, measure development, measure test and model fit   Order a copy of this article
    by Sachin S. Kamble, Shradha Gawankar, Rakesh Raut 
    Abstract: This paper attempts to develop, validate the measures for LSCP and also test the influence on the organisational performance. The data was collected through questionnaire survey from 154 transport service providers from Mumbai and nearby costal region in India. In the first phase, confirmatory factor analysis was used to test the validity of the proposed measurement scale for all the identified constructs. Second phase tests the relationship between the identified constructs and organisation performance using SEM. In doing so, we map a positive relationship between logistic supply chain performance (LSCP) and organisational performance (OP) which ultimately leads to enhance the performance improvement within firms and across the supply chain.

  • Assessing the responsiveness of supply chain - structural equation modelling based approach   Order a copy of this article
    by P. Raghuram, P.G. Saleeshya 
    Abstract: Companies worldwide have now realised 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 modelling. 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.
