The Study On Information Sharing And Contracts Design In Supply Chain

With the rapidly development of science and technology and fast globalization, the environment faced by enterprises has been totally changed. So the competitions will be happened among supply chains rather than just among some independent enterprises in 21st century. Strengthen the competitive capacity of the supply chain is the key element of the successful enterprises management. Therefore, it is very important to build up the competitive capacity of the supply chain through two basic methods: information sharing and contracts design. Combined with the inventory theory, contract theory, decision-making theory, game theory, probability theory, differential theory and so on, taken the methods of theory analysis, simulation, and empirical case studies, this thesis studies these problems systematically, such as the value of partial information sharing, full information sharing, the existence and design of perfect and win-win contracts, the wholesale price contract's influences upon inventory management models.First, we discuss the meaning of supply chain and supply chain management systematically, give the purpose of this study on information sharing and contracts design, define the perfect and win-win contracts, review the current literatures of information sharing and contract design research.Second, in regard of a two-echelon supply chain system with one retailer and one manufacture, we construct the mathematical models for sharing the retailer's promoting planning or manufacture's supply information, analyze the reduction of running cost and average inventory in the supply chain through analytical analysis and simulation.Third, under the strategy of fulfill the order ahead, the mathematical model and the values of coordination and information sharing between a manufacture and a retailer is built up and analyzed, the enumerative algorithm is given to calculate the optimal solution of the supply chain with order fulfill time and market demands being even distributions, at last the influences of parameters variation upon the profit of the supply chain are studied through 24000 simulation cases.Forth, we discuss the meanings of buy back contract, revenue-sharing contract, quantity flexibility contract, sale rebate contract, and quantity discount contract, study the necessary and sufficient conditions for these five contracts being perfect and win-win ones in a two-echelon supply chain system with one retailer and one manufacture that faces newsvendor problem. Then we give the necessary and sufficient condition for the perfect and win-win revenue-sharing contract with the same revenue-sharing ratio, and at last figure out a set of perfect and win-win...
