A Framework for Sustainable Supply Chains: Evaluation of Implementation Barriers
by Bikram K. Bahinipati, Swayam S. Panigrahi
Abstract: Sustainable supply chain Management (SSCM) identifies and integrates a set of key business processes to provide products, services and information for value addition through collaborative and sustainable efforts of supply chain members. In order to accomplish this objective, sustainable supply chain practices need to be implemented to ensure a strong and healthy society without compromising the performance limits and governance, while attaining the environmental, economic, and social goals. The literature and industry experts have identified the critical inhibiting indicators for the successful implementation of SSCM practices. The sustainable supply chain evaluates different alternatives against multiple sustainable practice attributes which should be considered simultaneously to arrive at an appropriate implementation decision. The focus of this paper is to develop a framework for implementation of sustainable practices in Indian Small and Medium Enterprises (SMEs) for competitive advantage. An analytic hierarchy process (AHP) framework has been proposed for SMEs to resolve the conflicts and quantify the impact of critical inhibitors on SSCM implementation. The assessment of the priority weight of these inhibitors would help the decision makers to prioritise the action plan for implementation of SSCM practices. A sensitivity analysis is conducted to identify the sensitive points in the decision process.
Keywords: Sustainable Supply Chain; Implementation Barriers; Analytic Hierarchy Process; Sustainable Practices; Sensitivity Analysis; Implementation framework.

Exploring environmental sustainability in the food service supply chains
by Gyan Prakash
Abstract: This paper aims to identify factors of environmental sustainability in the context of food service supply chains (FSSC). Factors of environmental sustainability have been identified from the review of literature. These factors have been used to capture desirability of restaurant owners and suppliers for adoption of the environmental sustainability indicators. Data have been gathered using a seven point Likert scale. Hierarchical cluster analysis has been used to combine these indicators into set of clusters. Mann Whitney U test has been used to assess the differences among the perceptions of the groups. Ten factors of environmental sustainability condense into four clusters. Application of Mann Whitney test reveals differences among the groups across certain indicators. Some indicators are interlinked with each other which pose challenges towards environmental sustainability. Restaurants owners as well as their suppliers find generic indicators to be more effective in the achieving environmental sustainability. It contributes to the body of knowledge by presenting a perspective from an emerging economy. This paper provides insights on adoption of environmental sustainability in FSSC.

Managing Welfare Driven Supply Chains: Insights from the Indian PDS
by Gyan Prakash
Abstract: The objectives of this study are to understand the design, implementation and monitoring of social food supply chain. As a case in point Indian public distribution system (PDS) have been investigated. In India a public distribution system (PDS) and its improved version targeted public distribution system (TPDS) was carved out as a novel system of safety net operations for the distribution of scheduled commodities to the targeted citizens through a network of institutions comprising Food Corporation of India (FCI) warehouses and fair price shops (FPS). The methodology adopted is a mix of literature review, document analysis, interview with policy makers, officials responsible for distribution of food grains, fair price shop owners and survey of end users. It is inferred that this system is fraught with inefficiency at all stages of the supply chain and service delivery is poor. A hybrid approach is proposed to retain the current PDS supply chain while making suitable process redesigns, introducing ICT based interventions and involvement of private actors in service delivery.

An Insight into Centralized Sourcing Strategy for Enhancing Performance and Sustainability of Multi-tier Supply Network
by Avinash Bagul, Indrajit Mukherjee
Abstract: In a multi-tier supply network, sourcing strategy, consisting of supplier selection (SS) and order quantity allocation (OQA) to selected supplier(s), is a critical and challenging task for practitioners. Every player, in every tier of sourcing network, attempts to select quality conscious suppliers and optimize its own inventory cost per unit time for OQA. However, this may results in sub-optimal solution(s) for overall multi-tier supply network. Considering centralized sourcing strategy for SS and OQA may provide global best solution and sustainable supply network. This paper attempts to quantitatively illustrate inventory cost saving for coordinated centralized sourcing strategy for all tiers compared to independent decentralized sourcing strategy at individual tier in the supply network. Suitable mathematical models (single and multi-tier) and corresponding solution framework is used to determine local optima and global best solution for a comparative analysis. A real life electric goods manufacturing industry case study is used to demonstrate significant cost advantage for a centralized as compared to decentralize sourcing strategy. Sensitivity analysis with varied unit material price is also illustrated in this study.

Developing the preferred supplier relationships A case study
by Sunil Kumar C V, Srikanta Routroy
Abstract: The manufacturer-supplier relationships along the manufacturing supply chains have become the rich sources for generating the sustainable competitive advantages. Consequently in developing these relationships, often the manufacturers are inclined to have preferred supplier relationships established so as to cater their long term requirements. In this regard, a manufacturer must adopt a scientific process to favourably associate with few selected suppliers and eventually choose to develop the right suppliers in order to generate the supply base advantages over the other manufacturers. However, in practice often the right suppliers are not systematically promoted and thereby the opportunities for achieving the potential growth of manufacturing supply chains are greatly lost. Considering this issue, the current study is focused on proposing a systematic approach for establishing the preferred supplier relationships. By implementing the proposed process, a manufacturer can ensure that the right suppliers are professionally endorsed and the manufacturer-supplier relationships are optimally flourished.

Coordination Quality Index: A metric for measuring the quality of coordination efforts in humanitarian supply chain
by Anand Gurumurthy, Lijo John
Abstract: Coordination challenges in humanitarian supply chain (HSC) have plagued logistician for long in the humanitarian domain. Since coordination requires deployment of resources in terms of manpower, material and money, it is a cost center by (Balcik et al., 2010; Stephenson, 2005) all the associated members of the HSC. The effectiveness of the coordination practice has a direct consequence on the performance HSC operations. Therefore, it becomes imperative for the managers to quantify the effectiveness of the coordination activities for improving the operations of HSC. This study aims to address this gap and provide humanitarian agencies with a decision support tool to measure effectiveness of its coordination strategies in achieving the related benefits such as improved resource utilization, better information sharing, improved perception of value of coordination, streamlined organizational mandates, etc. Coordination Quality Index (CQI) is introduced to address this need. CQI is an aggregate measure of the degree of implementation of various coordination practices carried out by the humanitarian agencies. Furthermore, the application of the proposed methodology is demonstrated in the setting of Chennai Flood relief activities.The results indicate that the overall quality score obtained for coordination during the Chennai floods was moderate to low. Though, the perception of value for coordination and effectiveness of resource utilization was from moderate to high, the major reason for the poor coordination was due to the poor information sharing, large diversity of actors and lack of streamlined organizational mandates. It was also found that, though there were efforts to improve coordination between the stakeholders in HSC during the relief operation of Chennai floods, benefits of the coordination were not achieved.

by Om Prakash Yadav
Abstract: An effective quality management system is critical for having a smooth and efficient supply chain system. Establishing and maintaining quality systems is more challenging for smaller companies compared to larger organizations. This paper presents a cost effective and do-it-yourself approach to design and implement a quality management system for smaller organizations. It proposes a quality system implementation framework for small-medium sized companies to enable their transition from a no-quality system to having a more effective quality system. The study also proposes an effective continuous improvement and system maintenance plan after implementing the quality system. The proposed framework is validated using a case study of a small door manufacturing company. The findings of this study reveal several setbacks during quality management implementation and suggest means to overcome them. Benefits and results achieved by implementation of proposed framework will be useful for quality practitioners, quality managers, consultants, and engineers, especially in small companies.
