Abstarct: The problem of closed-loop supply chain and reverse logistics has been an increasing attention because of the environmental worrying, strict rules, and the benefit of this kind of supply chain management. This study aims to develop a model for the problem of closed-loop supply chain network with ability of recycling the products. So, after definition the parameters and variables, a nonlinear mixed integer mathematical model in multi-product condition has been developed to minimizing total cost. Purchasing cost in the assembly section, renovation the collected products, gathering cost, repayment to customer, and eexcretions cost have been minimized in the sweep networks. Strategic design of the supply chain with tactical planning contains of the production, distribution, Reclaiming, recycle, and reusing is done simultaneously in the proposed model. The proposed model is run by GAMS and the result is analysed for some sample problems.
