While regulations have advanced product take-back in some markets, challenges to increasing product reuse and remanufacturing remain. Most research to date has focused on original equipment manufacturers taking back and remanufacturing their products, which is often problematic. The present study demonstrates that there are emerging opportunities for small companies with innovative business models to enter the market and advance product end-of-life (EoL) management. The paper examines the biotechnology industry – a growing sector with high spending on lab equipment and relatively short lifespans of research and development instruments. Building on previous research and analysis of industry practices and emerging drivers for product reuse and remanufacturing, the authors propose a framework for sustainable EoL management that includes five managerial drivers: financial benefits, space, ease/convenience, information, and sustainability goals. The paper concludes with discussion of the lessons learned and practical implications for managers in charge of purchasing or disposing of surplus equipment. 相似文献

For many manufacturers, the cost of replacing returned products may more than offset the cost of producing parts with a higher quality. This is especially true if good parts from returned products are used to remanufacture aftermarket products. Furthermore, such policy allows for satisfying a customer population with a variable expectation for acceptable quality. In this study, the total cost of supplying a given demand is derived as an analytical function of the targeted primary production rate and product quality when the demand is satisfied with a combination of primary and remanufactured products. The decision variables of this function consist of the primary production rate and the designed product and production quality. This cost is then minimised to determine the production rate and the optimum quality to target. A numerical example is provided and used to demonstrate the application of this function. This example also demonstrates the use of the proposed solution for optimising quality when there is a limit on primary production size. The example also demonstrates the use of the function for optimising service levels. The results show a close match between the theoretical functions developed in this study and those obtained from a Monte Carlo simulation model. 相似文献

Traditional supply chain design is merely based on the open loop or forward flow of materials, neglecting reverse flow for recovery of materials despite the recent concerns of customers and governments about environmental and production cost reductions. New supply chain design should be closed loop which implements traditional supply chain concepts with reverse flow or a material recovery system to reduce production cost and enhance customer satisfaction about environmental consciousness and to meet legal requirements. In our research, we designed a closed-loop supply chain which consists of recovery options such as collection centres and remanufacturing plants (reverse flow) in addition to traditional supply chain tiers (forward flow), and tried to find the best location for these facilities in a discrete space based on decision makers' opinions. Since there are uncertainties about decision parameters in an uncapacitated facility location problem, we implemented the fuzzy TOPSIS method to solve the location decision problem and find the best place to locate a remanufacturing facility. 相似文献

This paper reviews the current development and practices in closed-loop supply chain under content analysis of the published literatures. A comprehensive literature review of recent and state-of-the-art paper is vital to draw a framework and to shed light on the future direction. We have reviewed here articles on remanufacturing with special emphasis on literature related to acquisition management of returned items. For review of articles, various web-based search engine, books, journal and conference proceeding are selected and reviewed. The research papers are then analysed and categorized to construct useful foundation of past research. The review shows that current researchers are focusing on devising pricing policies to attract used products from customers. Finally, gaps in the literature are identified to suggest future research opportunities. 相似文献

Return items received from end customers for remanufacturing is uncertain in nature. In this paper, we considered that return demand function is uncertain and sensitive to the acquisition price and the availability of used products in the market. A mathematical model was developed to investigate the impact of the availability of return items in the market on acquisition price management. Here, three different methods of collection of return items from the market are considered: direct method, indirect method and coordinated method. A numerical study was conducted to illustrate the mathematical model, and an extensive sensitivity analysis was carried out for the three different methods of collection to examine the impact of market size and the available dependency factor on acquisition price and the channel profit. The results show that the total channel profit increases when the acquisition price increases for the direct method of collection. Furthermore, the results reveal that the total channel profit increases when the market size increases for the coordinated method of collection compared with the other two methods of collection. 相似文献

This paper addresses sustainable benefits of remanufacturing tyres. An agent-based simulation approach is used to tackle this research problem by identifying different agents such as tyre, collector, recycler and remanufacturer. Details related to every agent are provided to show the decisions taken by these agents and the impact that may have on tyres' remanufacturing industry. Relying on input data from published reports and papers by academics and professional organisations, experiments are conducted on various scenarios to show the benefits of increasing the retread percentage of passenger car tyres. The results show that retreaded tyre can capture almost 25% of replacement (sales) market, resulting in significant reduction in scrap tyres and raw material consumption. This percentage can further be increased by increasing the number of retreads per used tyre and the life of tread rubber. The output results help in finding the profit break‐even point at various levels of retread. The results also show other decision-making implications, particularly related to rejection rate and ways to reduce it. 相似文献
