Nowadays, consumption of materials for producing many goods at human life and rapid technological advances has driven organizations to address and make efforts to improve efficiency in their supply chain. Increasing efficiency in reverse logistics processes such as the recovery of the returned products or disposal of end-of-life products is one way in which firms attempt to maintain and increase competitiveness and market share. The volume and monetary value of product flowing in the reverse direction within the supply chain has been andcontinues to be increasing, particularly as environmental, legal, and customer service requirements increase throughout the marketplace.In this paper,after some explanation, a mathematical model is developed which minimizes the costs of setting upthe network and the relevant transportation costs.Thus,we seek to find a solution for optimized design of a reverse logistics network and the best recovery situation.Also in this article ,we use a case study numerical elements for validation of modle.
