Reverse supply chain is the process of returning the products from their production or consumption centers back to the supply chain in order to extend their life cycle and gaining competitive advantage. In this paper, these chains and their difference with forward supply chains are introduced from previous researches. Then the different flows of products, disposal options, processes and members are presented. For reverse supply chains the level of information sharing and the uses of IT are modeled at this paper. Finally, the criteria for selecting an information sharing technology are identified and a hierarchical model is suggested to achieve the managerial insights conceptually
