A comprehensive reverse supply chain model using an interactive fuzzy approach – A case study on the Vietnamese electronics industry

Reverse supply chains (RSCs) have gained much attention from governments, companies and scholars due to increasing levels of environmental concern, resource depletion and regulation. In Europe and other developed countries, RSCs have been imposed by regulation so that manufacturers take greater responsibility for their end-of-life products. In developing countries like Vietnam, this situation is much more complicated since there are many destinations for end-of-life products other than the take-back systems of their manufacturers. Consequently, product flow quantities to RSC facilities in Vietnam, as well as other parameters, are vague and uncertain. To help electronics companies set up more effective RSCs, this study employs a fuzzy approach to account for such uncertain parameters. Furthermore, risk factors are integrated into the proposed model to make it more comprehensive. The solution approach gives much greater flexibility for decision-makers to obtain a satisfactory solution. © 2019 Elsevier Inc.
