The optimization of reverse supply chain supernetwork

In this paper, we present a green reverse supply chain supernetwork model, which consists of I manufacturers, J distributors, M markets and N recyclers. Hereon this base, the optimality conditions for the manufacturers, distributors, the consumers and the recyclers are established respectively using the variational inequalities. Then we describe the optimization situation for the supply chain supernetwork model and get the stationary points for this situation. An example is illustrated to validate the utility of the supply chain supernetwork model in the last part.
