Supply Chain Coordination On Asymmetric Information

With the increasing competition, in order to achieve a quick response to rapidly changing customer's requirements, supply chain management has been receiving more and more attention of managers, consultants and researchers. Among various entities and functional units in a supply chain, coordination pattern is needed to achieve a global performance optimization. Because supply chain members are independent enterprises, they make decisions to optimize their own objectives. In order that the enterprises' behavior follows the optimal action of the supply chain, it is necessary to design appropriate mechanism to restrain and coordinate the entities on the supply chain. The supply chain management applies supply chain contracts as an effective managing tool to control incentive conflicts and to improve the supply chain performance. The study of supply chain enterprises' game and cooperation problems stemmed from supply chain management in reality to reach win-win is an important research area of supply chain contract.The paper combines the theories and methods in some fields such as Operational Research, Economics and so on to study the problem of supply chain coordination contract on asymmetric information. The main content of the dissertation as follows:Analysis the problems of coordination of supply chain on asymmetric information, including the motivation factors of the three stage supply chain coordination, and the co-ordinated approach and problems of the enterprises elaborate the three stage supply chain coordinated method. The paper also showed the supply chain contract coordination mechanisms according to the coordination problem of supply chain.Supply chain contract will determine the way of enterprises distribute their business resources and the interests with other enterprises. When the contracts are under the coordination mechanism and make the activities of the supply chain satisfy the Nash equilibrium, the supply chain members will not deviate from optimal behavior. In this kind of mode, the contract played a role in coordinating the supply chain. The paper summarizes the common characteristics in a variety of supply chain contract models. The characteristics include that the supply chain usually is two stages, the sales cycle is often short, the core enterprise is always manufacturer, and the contract is provided by manufacturer to other enterprises in supply chain. Therefore, the paper established a common supply chain contract model and analysis two kinds of supply chain (the integrated supply chain and the vertical separated supply chain). The contract model can encourage the enterprises to choose strategy which can optimize the whole supply chain.The next part of the paper, the n-stage ordering strategy is made considering the price discount contract of supply chain. The market demand is fixed in the case. The dissertation respectively analysis a two stage supply chain including one supplier and one retailer and a three stage supply chain including one supplier, one retailer and one logistics operator. In this supply chain contract model, the supply chain member enterprises can obtain more interests, so this strategy can make the supply chain coordinated, and the supply chain members are also welcome to use it.
