Pricing Model In The Closed-loop Supply Chain Research

In the whole decision-making of closed-loop supply chain, the product pricing decisions is a key element related to enterprise efficiency and performance of the closed-loop supply chain. However, there is goal conflicts and private messages in closed-loop supply chains, which may lead to profit conflicts. Therefore, this paper particularly analyzes the product pricing model of close-loop supply chain under symmetrical information and asymmetric Information and network equilibrium by combined qualitative and quantitative analysis with game theory, optimization method and variant inequality as tools. In one hand, the work is of much value in theory. On the other hand, It provides a reference of production operators and guidance of improving the overall competitiveness. The main thesis of the research and the results are as follows:(1) Five pricing models of closed-loop supply chain under asymmetric information were researched, in which the amount of recovery was affected by recovery price.Pricing strategies of the five closed-loop supply chain models were calculated and the relationship between profits and recovery cost factor were given throgh the comparativeof pricing strategies. Therefore, the manufacture's choices of closed-loop supply chain model was drawn. Corrdination mechanism based on contract was designed to coordinate the nodes in the closed-loop supply chain profits.(2) According to the recovery market conditions whether the manufacturer can observe, three MRCRM pricing models of closed-loop supply chain under asymmetric information were studied. when manufacturers and retailers can observe the recovery market conditions, It studied the optimal pricing strategies. when manufacturers can not observe the recovery market conditions the separation and mixed contract pricing model which the manufacturers adopted were stuided and the optimal pricing strategies and profits were caculated.(3) A closed-loop supply chain network equilibrium model which consists of anumber of independent decision-making entity was studied. By analyzing the competitiveness of various markets and its equilibrium targets, changing variational inequality problem into the equivalent form of the complementarity problem, giving the economic interpretation, a closed-loop supply chain network equilibrium model was established. A solution algorithm was given to derive the equilibrium price and equilibrium trading volume. Finally, a numerical example was given.
