Integrated Inventory Model for Return-able Transport Items considered Container Return Time and Fuzzy Demand (EI)

Abstract

This study considers single supplier supplying single buyer with finished products packed in returnable transport items (RTIs) to facilitate safe transport to the customer. Empty RTIs are collected at the buyer and returned to the supplier. The return time of RTIs is considered to be stochastic in this study because of unforeseen events, such as damages of RTIs or labor shortage to empty RTIs. We formulate the problem of integrating the flow of both the finished product and RTIs and minimizing the supply chain expected total costs as a non-linear program. Secondly, it presents the results of this study in which the behavior of the model is analyzed. In addition, we add fuzzy to this study in order to acquire a more realistic result because of the uncertain environments.
