The direct supply chain has become increasingly implemented in all industries to ensure the customers’ satisfactions at the lowest delivery time and at the minimal cost. The goal of this work is to propose a modeling methodology of the integrated the reverse logistics chain in the direct supply chain with the inclusion of the possibility of selling in a secondary markets. The first part of the article presents the problems caused by the integration of the return logistics chain in the direct chain. The second part presents a literature review of the reverse logistics and its importance. The third puts light on our methodological approach to modeling and analysis of the supply chain. The fourth part is subject to the application of the proposed methodology in a case study. The final part will represent the conclusion and prospects of this paper.
