Considering Discount problem in closed loop supply chain network according to sustainability problem based on new algorithms

One of the most important and strategic decisions that can affect competitive advantages and other decisions in the supply chain is the design of the supply chain network. The study addresses the economic and sustainability issues in the supply chain. In this study, a mixed linear programming model has been formulated. In the design of the proposed article has also considered the issue. In solving this problem, are used for algorithms: GA, ACO, WOA & KA. The efficiency and evaluation of the model were investigated according to the proposed algorithms.
