Fuzzy Closed- Loop Supply Chain considered Container Return Time

Abstract

This study considers a scenario where single supplier supplying a finished product to single buyer. In order to ensure safe transportation for the customer, finished product is packed in returnable transport items (RTIs). Empty RTIs are retreated to the supplier and used for the next delivery. We consider the return time of RTIs is stochastic in this paper as a result of some unexpected factors. We promote the problem of incorporating the flow of both the finished product and RTIs and formulating a non-linear programming model of the closed-loop supply chain expected total costs. Secondly, we analyze the results of this paper in which the behavior of the model is revealed. Additionally, we add fuzzy to this paper in order to acquire a more appropriate result under the uncertain environment.
