Supply Chain Equilibrium Model And Its Analysis Based On Game Theory

Because the science and technology progresses unceasingly and the market competition is becoming increasingly fierce, the competition between individual enterprises has been gradually transformed into the competition between the supply chain. With the supply chain concept more and more accepted by the enterprise managers, the supply chain management of theoretical study and practical application are in a continuous deepening and optimizing process. The game theory becomes the main method researching supply chain equilibrium model, when the system members'management objectives conflict, using game theory to coordinate the interests of all parties may be a wise choice. Therefore, the research to the supply chain equilibrium model is very important to the supply chain management, and is one of the hot spots on the supply chain.Based on the above analysis we selected this topic as the research objective. The research objective is two class supply chain equilibrium model, Specific studies as follows:Supply chain pricing decision, coordination as well as the uncertainty in supply chain were summarized and reviewed, and game theory as well as its application in the economic was briefly introduced, and we introduced the basic newsboy model, bi-level programming knowledge.After analyzing the existing two-level sole-manufacturer-to-sole-retailer model, we give the improved pricing strategy model that meets the practical need. Then based on the improved model and game theory, change the formulation of pricing strategy in supply chain management practice to fit cooperation environment. The improved model can maximize the interest of single members while meeting the basic system efficiency demand. Only in this way we can make sure the maximum economic and social values of supply chain.A decentralized supply chain model between a single manufacture and some retailers without any relationships was improved. A supply chain model between one manufacture and more retailers with competition relationships was proposed, the manufacture is the leader who sets the wholesale price, and retailers are the followers who determine their retail price which the demand depends on. The original model did not consider any competition among retailers, its difference with the realistic scene. Therefore the new model considered the competition relations among retailers.In a Manufacturer-leaded supply chain, we compared the proceeds of the supply chain members in the state of non-cooperation, as well as cooperation state.In the premise that the retail price and the market demand have inverse relation we study the supply chain cooperation strategy, and find solutions to the problem. In the premise that demand and the price are relevant, we establishment supply chain contract's mathematical model, and discusses the price factor how to influence the supply chain contract's cooperation strategy.A two-stage supply chain dominant by retailer was discussed , and how the supply chain members work out optimal policy under certain situation and uncertain situation respectively. Also the problem about supply chain equilibrium model.
