Abstract :
Today, the debate on the recovery and reuse of consumer products has become particularly important. Since the closed loop supply chain is not only a stream of forward but also a reverse flow, therefore, companies are succeeding to create a direct and reverse supply chain of integrity. In the present study, after reviewing the subject literature, a more completed and comprehensive model is presented than the previous models. The model is multi-objective, multi-level, and single-product with product return in the uncertain conditions. The objective functions of the model include minimizing costs, increasing the profit from the quality of the recycled product, increasing the cost savings from recycling and environmental impacts. In order to solve the multi-objective problem approach (TH) is used, which is one of the methods for converting multi-objective functions to single-objective. To validate the proposed model, a numerical example of the design was solved and for analyzed using the GAMS software. And the results of the sensitivity analysis are described below.
