Research on Return Mechanism of Supply Chain Based on Cooperation Game Model

A kind of return mechanism of supply chain based on Nash negotiation model is proposed firstly. Although the optimal equilibrium solution of this model can satisfy the individual rationality and collectivity rationality of cooperation game, supplier and retailer allocate the increased benefit of supply chain averagely unconditionally under the optimal equilibrium solution of this model. To overcome the equalitarian phenomena, a further kind of return mechanism of supply chain based on asymmetric Nash negotiation model according to the former model is proposed. The most remarkable character of the further model is that the cooperation contribution rates of supplier and retailer are considered into the model. And the cooperation contribution rates of supplier and retailer are measured by Shapley value of cooperation game theory
