Study On Supply Chain Coordination Based On Option Contracts Under Environment Of Uncertainty

With the development of technology, the trend of globalization has appeared in the economy. The competition between supply chains is becoming more and more intense. The coordination of supply chain is of great significance to improve the overall competitiveness. Comparing to the enterprise environment, there exist market demand, production yield and supply uncertain risks in the process of operation, these uncertain risks can cause to supply and demand imbalance, inventory accumulation, profit damage and other hazards. Based on the conditions mentioned above, this thesis studies the supply chain coordination based on option contracts under environment of uncertainty, which takes a two-level supply chain system consisting of one retailer and one supplier as the research object. The main contents are as follows:(1) The coordination of supply chain under uncertain market demand is studied. The combination of the wholesale price contract and option contract is applied to supply chain coordination, which is used to solve the problem that market risk is borne independently by the supplier. Through deeply analyzing and the retailer optimal combined order strategy and the supplier optimal production strategy, it shows that the supply chain system profit can be rationally distributed, the supply chain can be coordinated and a win-win situation can be achieved by choosing appropriate option price. Finally, the numerical examples and sensitivity analysis are given to verify the validity of coordination.(2) The coordination of supply chain under stochastic market demand and random production yield is studied. The supply chain coordination model is developed based on the wholesale price and option contracts, where considering the retailer not only orders wholesale price contract products, but also orders a certain number of options. The research shows that the individual decision can be motivated consistent with the overall decision, and the supply chain system profit can be rationally distributed, and the supply chain member’s revenue can be increased by choosing appropriate contract parameters. At last, the numerical examples are presented to verify this conclusion, and the sensitivity analysis of some important parameters is carried out.(3) The coordination of supply chain for products with selling price sensitive market demand is studied. Considering the selling price is a decision variable, the supply chain coordination model is established based on the option contract under market demand and supply uncertainty, and then the optimal solution is obtained. The result indicates that the optimal performance of the whole supply chain can be achieved, and the supply chain system profit can be rationally distributed, and a win-win situation for member of the supply chain can be realized. Lastly, the theoretical results of the model are verified by numerical examples, and the effects of some parameters on the profit of supplier, retailer and supply chain are analyzed.
