- A new approach for supplier selection using fuzzy MCDM
by Reza Rostamzadeh
Abstract: The aim of this paper is to propose a new framework for supplier selection using FAHP and TOPSIS methods. As the human decision-making process usually contains fuzziness and vagueness, so linguistic values are used to assess the ratings and weights for criteria. A hierarchy multiple criteria decision-making (MCDM) model based on fuzzy-sets theory including FAHP adopted for finding weights of criteria and its sub-criteria and then for the final ranking of the suppliers TOPSIS method is used in a real industry case. This study concluded that the ranking of the main criteria and sub-criteria in all the suppliers are the same. Drawing on a real case, supplier A was identified to be the best supplier. Also, it can be said that TOPSIS method is a useful additional tool for the problem. More research is definitely called for within the context of studying a more complex supply chain with multiple supply network and nodes. There is also a crucial need for investigating other hybrid methods to find the optimum supplier. The proposed criteria can be applied both in industrial and service organisations with slight modifications.
Keywords: supplier selection; multi-criteria decision making; FAHP.
- A new model for achieving sustainable competitive advantage through operations strategies in manufacturing companies
by Amir Samarrokhi, Kouroush Jenab, Veeri Chettiar Arumugam, Philip D. Weinsier
Abstract: Theorists and practitioners alike emphasise the importance of competitive advantage in garnering maximum profit and performance. Still, there is a presence of continuous confusion among managers in measuring a company's competitive advantage with regards to its temporality and sustainability. In order to look into this issue, the authors introduced product lifecycle as a time-dimension measure and analysed its effects on optimum financial performance. In addition, this research study attempted to identify the appropriate operations strategies that could bring about sustainable competitive advantage. Operations strategies can be divided into four subcategories: low-cost leadership, quality differentiation, service differentiation and innovation differentiation. The primary data collected via questionnaires for this study came from the chief executive officers and chief operating officers of Malaysian manufacturing companies. Results were tabulated through the application of a multiple regression analysis. The study also proved that some of the operations strategies could ensure that these select manufacturing companies would obtain sustainable competitive advantage. However, it is important to note that the service differentiation strategy was limited in its contribution to temporary competitive advantage.

- A Structural Analysis of Green Supply Chain Management Enablers in the UAE Construction Sector
by SREEJITH BALASUBRAMANIAN
Abstract: The aim of the research is to develop a structural analysis of the enablers of green supply chain management (GSCM) in the UAE construction sector. An Interpretive structural modeling (ISM) approach is used to identify the contextual relationship of the enablers and to develop their hierarchical structure. Further the enablers are classified into visual quadrants on a graph using dependence-driving power analysis (DDPA). The hierarchical structure and graph will provide useful insights to corporates, government bodies and supply chain managers to understand and prioritize the key enablers of GSCM and the organizational strategies adopted by firms in the UAE. The study will contribute significantly to the first wave of empirical investigation in the region and will provide useful insights into GSCM in the UAE. A structural analysis of GSCM enablers as well as industry specific research of GSCM in construction sector is not previously developed in the UAE

- A note concerning physical space occupation costs in Vendor Managed Inventory with consignment agreement models
by Marcello Braglia, Davide Castellano, Marco Frosolini
Abstract: A new analytic formulation of the Vendor Managed Inventory with consignment agreement is proposed. It represents a modified and more realistic version of the model proposed in Braglia and Zavanella (2003). The evaluation of the stockholding related costs is herewith substantially revisited to consider the requirements of a standard VMI relationship with consignment agreement. In particular, the physical space occupation cost held by the buyer is introduced as a component of the overall holding cost and is referred to the maximum stock level, rather than to the average value, as proposed in the past literature. Finally, an implicit analytical solution is given and compared to the original one obtained by Braglia and Zavanella (2003).

- Cooperative inventory model for vendor-buyer system with unequal-sized shipment, defective items and carbon emission cost
by Wakhid Ahmad Jauhari, Anjar Setyo Pamuji, Cucuk Nur Rosyidi
Abstract: We develop an integrated inventory model for single-vendor single-buyer with deterministic demand. The vendors production process may be deteriorated during production run and results some defective items. The defective probability is assumed to be uniformly distributed. The shipment from vendor to buyer is made in unequal size over multiple shipments. We also incorporate the carbon emission cost and investigate the environmental impact on the model. The results of the study show that adopting unequal-sized shipment policy in the model which considering defective items will result in lower carbon emission cost and total cost compared to an equal-sized policy. Furthermore, the increase in defective probability will lead to the increase of carbon emission cost.
Keywords: defective items; integrated inventory model; supply chain; unequal-sized shipment; carbon emission cost.

- Green supply chain practices and its impact on organisational performance: an insight from Indian rubber industry
by Rameshwar Dubey, Surajit Bag, Sadia Samar Ali
Abstract: The purpose of the paper is to investigate the impact of green supply chain practices on organisational performance in Indian rubber industry. The present study has adopted two prolong strategies that includes critical literature review published in reputed journals to identify research gaps and identify variables and survey methodology using structured questionnaire. In order to validate, variables we performed exploratory analysis and identified parsimonious factors which are orthogonal. The orthogonal factors are named as technology and best practices, supplier relationship management, waste reduction through collaborations and regulatory norms and two measures for organisational performance, i.e., business performance and environmental performance. The multiple regression analysis suggests that 'supplier relationship management' and 'waste reduction through collaboration' are found to be positive determinants of 'business performance'. The multiple regression analysis using parsimonious factors were regressed on environmental performance. The output suggests that 'technology and best practices' and 'waste reduction through collaboration' are found to be positive determinants of 'environmental performance'. The analysis suggests that 'regulatory support' is not found to be statistically significant. The unique contribution of present study is GSCM-business performance and GSCM-environmental performance framework for Indian rubber industry.

- Comprehensive view of logistics flexibility and its impact on customer satisfaction
by Tejas R. Shah, Mahendra Sharma
Abstract: The volatility and uncertainty in internal and external environment has made logistics and supply chain issues more complex. Customer responsiveness and flexibility are the keys to responding to market volatility and uncertainty thereby gaining competitive advantage for firms. Most relevant studies about logistics flexibility reveals that it is contextual in nature and do not have stable components. This fills this gap by exploring logistics flexibility and its components at supply chain level. The study also identifies the non-contextual nature of components of logistics flexibility. The purpose of this paper is to explore the relationships among components of logistics flexibility and its impact on customer satisfaction. The dichotomy of flexible logistics competence and capability can help to differentiate the sub-dimensions of logistics flexibility that are critical to their customers from the sub-dimensions that support these capabilities. This research helps to understand that flexible logistics competences as well as capabilities of the firm are important to generate customer satisfaction.

- Status of service purchasing capability in networked supply chains, a literature review
by Vesa Kilpi
Abstract: The subject of this review is to investigate how service purchasing has been covered in recent literature. In marketing, the paradigm shift over the past ten years has been towards service and systems capabilities, yet research into the development drivers and needs in purchasing still seems to be in an initial phase. Customer-centric systems delivery is still being supplied by manufacturing-based purchasing processes. The opportunities provided by innovative information technology, global supply markets and integrated supply chains are developing the supply of services. This paper draws the map of this current status and suggests some paths forward.

- Internal supply-chain competition in remanufacturing: operations strategies, performance and environmental effects
by Emmanuel D. Adamides, George Papachristos
Abstract: This paper investigates the competitive and environmental effects of different operations strategies of Original Equipment Manufacturers (OEMs) and semi-independent remanufacturers, which simultaneously cooperate and compete in different stages of a closed-loop supply chain. In particular, a co-opetitive situation, in which remanufacturing is undertaken only by retailers while the OEMs role is restricted to recycling is considered. After adopting a resource-based perspective of competition, investigations are accomplished using system dynamics simulation modelling. The results of simulations indicate that, in the long run, OEMs, regardless of the operation strategy they adopt, are unable to (re)capture the market gained by the remanufacturers. However, some of these strategies contribute to the improvement of the environmental performance of the entire supply chain.

- Selecting inbound logistic policies: an ANP based multi-criteria decision making approach
by Francesco Zammori, Gionata Carmignani, Barbara Bigliardi
Abstract: This work presents a structured framework for the selection of the best inbound logistic policy, in a supplier-buyer relationship. Defining long lasting collaborations is a strategic issue, involving considerations of several parameters in terms of Benefits, Opportunities, Costs and Risks (BOCR). To support decision makers, the paper proposes a multi-criteria BOCR, which integrates a high level Analytical Hierarchy Process (AHP) with a low level Analytic Network Process (ANP). The latter one concerns operational issues, while the first one aggregates results from a strategically oriented point of view. The novelty of the approach relies in the way in which decision criteria have been structured in the form of decision networks: this makes it possible not only to streamline the analysis, but it also assures a high degree of flexibility. An industrial application is finally presented as experimental validation; obtained results demonstrate the quality and the robustness of the approach.

- Demand Forecasting Model for Slow moving items
by Dhakshayani Ekambaram
Abstract: Demand forecasting for a slow moving product is a critical area of concern and becomes crucial to find the optimistic forecast value for a slow moving product which results in huge inventory ultimately affecting the cost.
The two new models namely Probabilistic Demand Model (PDM) and Demand Size Based Model (DSBM) have been developed in this work by modifying the Crostons model. Probabilistic Demand Model (PDM) has been developed by considering actual probabilities in the demand size per period and Demand Size Based Model (DSBM) by directly estimating the demand size without any average per period considerations. Comparative study with the commonly used demand forecasting methods shows that the models follow close approximations to them and are versatile with different values of smoothening constant.
Keywords: Probabilistic Demand Model (PDM) , Demand Size Based Model (DSBM)
- Information and communication technology adoption in the Italian road freight haulage industry
by Pietro Evangelista, Edward Sweeney
Abstract: Despite the importance of information and communication technology (ICT) in the management of transport and logistics systems, there is a shortage of studies in the road freight haulage sector. This paper is aimed at filling this void through an exploratory survey on ICT adoption and the influencing factors carried out in the Italian road transport market. The paper provides a review of the previous research on this topic that allows the identification of research gaps that have been addressed through a questionnaire survey. The findings provide evidence of a passive stance on ICT usage characterised by the adoption of isolated applications. The financial risk associated with technology investment and human resources are the main barriers to ICT adoption, while the improvement of service level and the reliability of transport operations emerge as stimulating factors. The results suggest that the potential benefits of technology have not been fully exploited and a risk-sensitive stance on ICT is evident preventing the full incorporation of ICT into business processes

- Optimal Lot Sizing and Inventory Decisions in a Centralized and Decentralized Two Echelon Inventory System with Price Dependent Demand
by Dega Nagaraju, S NARAYANAN, A RAMAKRISHNA RAO
Abstract: In the present-day scenario of global competitive environment, the consideration of the elasticity of demand has become one of the significant factors for designing effective supply chain coordination. In this paper, an integrated inventory model for optimal lot sizing and inventory decisions for centralized and decentralized supply chain with a single customer and single supplier considering ordering/setup costs, carrying costs and transportation costs of respective entities has been developed. The main contribution of this work is to demonstrate the implications of a dependence factor over the optimality of inventory levels, number of shipments and the total variable costs under price dependent demand which in turn is a function of replenishment quantity with dependence factor. A computer program is written in MATLAB as per the solution procedure developed to solve the model. Numerical example is devised to illustrate the optimality of decision variables, and objective function and also the sensitivity analysis is carried out.

- Fuzzy EOQ models for deterioration items under discounted cash flow approach when supplier credits are linked to Order Quantity
by Sarla Pareek, Vinti Dhaka
Abstract: The article deals with a fuzzy inventory model for deteriorating items under a situation in which supplier offers the purchaser some credit, proportional to the ordered quantity by purchaser. Shortages are not allowed. The effects of the inflation rate find on the purchase price, ordering price and holding price, deterioration of units and permissible delay in payments are discussed in this article. A mathematical formulation is developed when inventory units are subject to fuzzy deterioration under inflation when the supplier offers a permissible delay to the purchaser if the order quantity is greater than or equal to a quantity which is specified. An Optimal solution is obtained and algorithm is also given for finding the optimal order quantity and replenishment time, which gives the minimization of the total cost of an inventory system in four different cases. The article concluded with a numerical example to illustrate the theoretical results where interdependence of parameter is studied for the optimal solution.

- An Empirical-Relational Investigation on Supply Chain Responsiveness
by Santanu Mandal
Abstract: Various supply chain capabilities like SC Agility, SC Resilience etc. encompasses a key factor in their conceptualization i.e. to respond to customer demand or environmental changes. So SC responsiveness is relevant in current context. Developing supply chain responsiveness in a global supply chain mandates presence of several relational attributes. Based on Resource Based View (RBV), Dynamic capability and relational view theories, the study empirically explores trust, commitment, communication, co-operation and co-ordination as relational resources in developing supply chain responsiveness. The study also considered the moderating role of environmental uncertainty on these relationships. The findings based on a web based survey of 141 supply chain professionals largely support our proposed relationships.

- Vehicle routing with cross-docking decreasing total cost in supply chain and storage unrestricted capacity using PERT search Algorithm
by Soroush Avakh Darestani, Mojgan Tahaei
Abstract: Cross-docking is a place which is determined according to routing for discharging goods as well as reloading and also goods can be maintained there for less than 24 hours. There are different ways with different restrictions in delivering materials from supplier to warehouse and then consumer. Direct loading. Is recognized as one of the important factors in controlling warehouse or physical flow and is included in managing supply chain. Also, it is planned for customer satisfaction as well as decreasing costs. This research presents optimal cross-docking methods and cars routing program aiming at decreasing transporting cost and determining the number of cars, cost of storage and cost of production and fixed cost of establishing a storage. Here, production capacity is restricted and storage capacity is un restricted and total loaded goods in each car must be less than its capacity. Therefore, factories are not able to send goods to each other. This model is provided for solving the problem the above goals and the proposed solution can improve the cost of this method and do the work in reasonable time. In the numerical example of the present research study, the number of nodes which must get the service is supposed as 6 (of course the number of nodes depends on the number we insert as the Entrance into the program ) and then by investigating the total Optimistic , Probable and Pessimistic costs between each two nodes ad by using the presented algorithm PERT, the amount of optimized obtained cost was 14 and the total variance was 3.6667. It should be noted that these amounts will be updated whenever the nodes, which must get the service, change.

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

- Joint Replenishment Problem for Multi -Echelon System with Planned Shortage
by Bassem Roushdy, Nahed Sobhy, Ahmed Mahmoud, Abdelrhim Abelhamid
Abstract: An inventory system with one warehouse and one retailer is proposed, planned shortage inventory amounts are allowed at both the retailer and the warehouse. During the ordering process, a major order cost for the lot is incurred at each location and a minor order cost is added for each item in the lot. Demand occurs only at the retailer with a constant deterministic rate. Two policies are considered for this problem; first, the centralized non-cooperative policy where a centralized decision making process is done on warehouse and retailer together to optimize their costs; second, the centralized cooperative policy wherein addition to the centralized decision process, the items at the retailer and the warehouse are replenished jointly to gain the advantage of reducing the major order cost. In the first policy, the objectives here are to evaluate the optimum order interval for each item (i), while in the second policy the objectives are to determine the common order interval, the associated multiple integers and that determines the time of order for each item, and the optimum inventory planned shortage amounts, for each item at each location, which minimize the total inventory cost for the echelon system.
Keywords: Joint Replenishment Problem; Multi Echelon Inventory; Planned Shortage.
- An Exploratory Study of Supply Chain Risk Management in the New Zealand Fast Food Industry
by Yiran Cui, Chuda Basnet
Abstract: This paper reports on exploratory qualitative research into the current practice of supply chain risk management in the New Zealand fast food industry. The study found that the New Zealand fast food industry depends heavily on import from other countries and overseas suppliers for the large amount of raw materials required by the industry. These suppliers hold dominant power in New Zealand fast food industry. As a result, fast-food restaurants have limited room for switching to contingency suppliers in disruptive situations, such as natural disasters or earthquakes. Furthermore, the study also shows that the fast food industry has increased vulnerability due to the stringent food safety and health standards and customers increasing awareness of food safety issues.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

- The selection criteria of global distributors in the fire protection industry
by Islam El-Nakib, Sara Elzarka
Abstract: In the supply chain of firefighting protection industry, the selection of the right overseas distributors is a strategic advantage for the manufacturer. Improper selection of potential overseas distributor can negatively affect the supply chain performance. Thus, this research tries to point out the current selection criteria used by the Fire Fighting and Fire Alarm Products Manufacturers (FF/FA PMs). In addition, the research attempts to determine how FF/FA PMs evaluate the following four criteria to select the overseas distributors: a) influence in the market, b) financial strength, c) commitment and d) logistical capabilities.The conclusion of this study is that selecting the right overseas distributor is a main requirement for FF/FA PMs effective performance. It is recommended that the company who looks to become an overseas distributor for FF/FA PMS should know the manufacturers requirements from the distributors; also; manufacturers should have predetermined criteria based on which they can select distributors who can represent them in the market.

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

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

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

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

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

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

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

by Mohamed Syazwan Ab Talib, Abu Bakar Abdul Hamid, Mohd Hafiz Zulfakar, Ai Chin Thoo
Abstract: There is a growing demand for Halal-certified logistics service, but the supply of such logistics service is limited. This study asserts that there is a potential area for research, and argue that logistics service providers (LSP) are resistant to adopt Halal logistics operation. Therefore, the purpose of this study is to determine the barriers in adopting Halal logistics operation. Additionally, this study tries to highlight the core reasons behind the barrier to Halal logistics operation. This study fills in the gap exist between insufficient supply of Halal LSP and the rising demand for Halal logistics. Semistructured interview technique is used to gather information from four Halal LSP in Malaysia. The respondents are identified from purposive judgement sampling. Four major barriers to Halal logistics operation are identified, and there are four core reasons behind these barriers. This study appraised and contributed to the growing knowledge of Halal and Halal logistics. Research limitations are highlighted and future research agendas are proposed.
