Abstract
Purpose - The article aims to explore the product disposition strategies in reverse supply chains and to develop a framework to prioritize these strategies for effective reverse supply chain implementation. Design/Methodology/Approach –The disposition strategies, based on the literature review were selected, and fuzzy TOPSIS methodology has been applied for the prioritization of these disposition strategies. A case of cell phone manufacturing firm is discussed for the illiustration and validation of the methodology. Three respondants from the firm helped in exploring the disposition strategies and data collection of the firm. Findings - The results of the study show that dissemble and recycle is the most preferred disposition strategy for the firm. Redistribution of returned products after their refurbishing is second most prioritized disposition strategy. Landfill and inciretion of cell phones is the last and least prefreferred option for the firm. Research limitations/implications- The study will provide useful guidance to the firm for disposition decision making of cell phones returned to the firm. It will help academicians and practitioners for evaluating, improving and benchmarking the disposition strategies for the disposition of returned cell phones. One of the limitations of the study is that it only considers the single case of manufacturing firm. In future, more case studies may be carried out for generalization of the results. Originality / value - It is evident from the literature review that there are very few studies on disposition decisions in reverse supply chain. Also, disposition strategies for cell phones are first time being explored and prioritized.Hence, this study can be viewed as an attempt to increase the level of awareness on reverse supply chain issues.
Introduction
In today's highly competitive business environment, the success of any business depends to a large extent on the efficiency of the supply chain. Competition has moved beyond firm-to firm rivalry to rivalry between supply chains. Traditionally, businesses have concentrated on improving the forward supply chain for their products (e.g., manufacturer-wholesalerretailer-consumer). However, another important and emerging dimension of successful SCM is the reverse logistics process (Marien, 1988). As the business environment becomes more competitive, it becomes increasingly important for them to concentrate on optimizing the backward loop, as well. Reverse supply chain practices have been in existence for a long time, especially in the automotive industry, where manufacturers try to recover value from recycling car parts. Reverse supply chains differ from forward supply chains in information flow, physical distribution flow and cash flow. To manage reverse supply chain, companies need sophisticated information systems. Some of the technology involved in reverse supply chain is similar while in some areas the technology used differs from that of traditional supply chain. Technology used in reverse supply chain such as real-time inventory tracking system (bar codes and sensors) are similar to that used in the forward supply chain. On the other hand, activities such as repair optimization, slow moving inventory optimization, warranty tracking and de-manufacturing of product is different. In designing a successful reverse supply chain, it is important to know what type of product will be returned at which point in time at which place and in which condition. Hence, importance of data is immense.
