Study On Perishable Products Supply Chain Income Coordination Under The Condition Of Consumers Return

Domestic and foreign scholars have carried out some research about the costume return perishable goods supply chain income distribute coordination, the solutions and models have formed and completed gradually. However, there are some differences between scholar's research and the coordination contract used. Based on the condition of the customer can be free to return, the retailer is responsible for the sales and bear the cost of the premise, this paper try to find out the equilibrium point of the manufacturer led supply chain.Firstly, after setting various parameters and their relations, this paper study on how to deal with customer return problem in the two level supply chain. Through analysis of the benefits of both the retailer and the manufacturer in the case of customer returns, I conclude that the coordination of supply chain is not achieved by the coordination of the price of the purchase price and the wholesale price. Thus, the amount of the repurchase is added to the coordination contract to achieve the supply chain coordination.Secondly, the supply chain contract is used in a three-level supply chain of perishable goods and proved that the contract can effectively coordinate perishable products supply chain. This paper points out that the essence of perishable products supply chain coordination of the parties are still in the supply chain's bargaining power. Therefore, the model of cooperative game is introduced into the supply chain coordination.Finally, this paper uses the cooperative profit distribution model to study the supply chain of one manufacturer and multiple retailers. By improving the cooperative profit model to ensure that the income distribution is more consistent with the model hypothesis. At the same time, the expert evaluation method and the cooperative profit model are combined to obtain a model which can meet the demand of the income and the bargaining power.
