The Research Of Coordination About Interests Among The Members Of Supply Chain

Due to economic globalization, product diversification and technological progress, customer demand becomes highly uncertain in many industries. Decreasing the impact of the demand uncertainty and satisfying the demand has become a main economic activity for many companies. But usually the supply chain is made up of several different economic entities, which often make decision to maximize their profit.So the supply chain faces the double marginalization phenomenon: many decision makers in the pursuit of different goals, not only conflicts between each other, but will affect the overall supply chain efficiency.So supply chain contracts to coordinate the supply chain are used. Supply chain collaboration ensures that the profits of all members equivalent to the optimal profits of the supply chain.Based on the above analysis and appraisal, I select this topic as the research issue. This paper summarizes the supply chain contract models of the newsvendor problem. To maximize the overall profit of the supply chain, the paper describes optical models. In this paper, the supply chain contracts of some different situation are expanded studied. Concrete work of the paper as follows:1. Expand the supply chain which is made up of a single supplier- retailer to a supply chain which is composed of a single supplier-distributor-retailer. The need is related to the effort factors. After analyzing, an independent buy-back contract can not coordinate this supply chain. Design a supply chain contract based on effort sharing to achieve supply chain's cooperation for this supply chain. By designing parameters of the contract, the supplier and distributor share the cost of sales. This contract can coordinate the supply chain. The members of the supply chain can allocate supply chain profit by arbitrary ratio. The profit of the members depends on economic status of the members in supply chain. An example demonstrates the correctness of this outcome.2. Expand a supply chain of a manufacturer innovation investment to a supply chain of a supplier and a retailer innovation investment at the time. After analyzing, the profit of a supply chain of a manufacturer innovation investment is less than a supply chain of a supplier and a retailer innovation investment at the time. Design a quantity discount contract to coordinate the supply chain. An example demonstrates the correctness of this outcome.3. For a simple supply chain which is composed of a single supplier- retailer, the cost information of the retailer is asymmetric. After analyzing the profit of the retailer will be higher than the cost information sharing. Designed a contract in which the retailer can not make a false cost information, so the contract can achieve the supply chain collaboration. An example demonstrates the correctness of this outcome. Through this study of the paper, strive to make the theory of supply chain conform to the actual situation. The paper provides an idea for the supply chain decision-makers. This paper is based on the supply chain coordination. The results of this study can ensure that the entire supply chain optimization.
