Closed loop supply chain network design has attracted the attentions of many researchers due to the social and environmental requirements as well as the economic benefits. Most of the researchers have studied the design problem separated from the supplier assessment. Some other criteria except for price, regarding supplier features, the supplied part and the production process can have considerable effects on supply chain performance. In this paper, a closed loop supply chain network including production centres, disassembly, refurbishing, and disposal sites is considered. An integrated three-phase model is given so that in the first phase, integrated SWARA-WASPAS method is employed for suppliers’ evaluation; in the second phase, a new method is proposed in order to determine environmental-social scores of remanufacturing sites and in the third phase, a three-objective mixed integer linear programming model is developed. Determination of the eligible suppliers and sustainability of the supply chain considering economic, social and environmental objectives, are of most outputs of this model. Unsatisfied demand of customers are assumed to be lost. The numerical results show the validity of the model and the role of stockout option in reaching better solutions considering the sustainability metrics.
