The Discussion Of The Problem Of The Supply Chain

The challenge that the supply chain faces is the supply chain coordination is difficult to obtain. The supply chain contract is the effective supply chain coordination mechanism . This paper discusses some problems of the supply chain contract.Firstly , the problem of the supply chain coordination with revenue-sharing contract is discussed. A model is built up to discuss the revenue-sharing contract by using Stackelberg game theory. The revenue-sharing contract is compared to the buy-back contract. In the newsvendors case, the revenue-sharing contract is equivalent to the buy-back contract. The proper conditions of the revenue-sharing contract are discussed. And a numerical example is made to illustrate the application in practice of the revenue-sharing contract .Secondly, the problem of the supply chain coordination under disruptions with the revenue-sharing contract is discussed. The supply chain can be coordinated with the revenue-sharing contract under some setting. But this coordination may be broken off by product cost disruptions . An optimal emergency strategy for the supply chain under the disruptions is given ,and an adjusted revenue-sharing contract which has anti-disruption-ability is proposed to make the supply chain coordinated.Thirdly, the problem of the supply chain coordination under disruptions with the whole-sale contract is discussed. An optimal strategy under the disruptions is given. And we prove that ,for the supply chain under the whole-sale price contract ,only if the demand scale is changed largely by disruptions the supplier will adjust his production plan, but he will change his whole-sale price properly. And a numerical example is made to prove the conclusion.Then ,we discuss the problem of the supply chain coordination under disruptions with the buy-back contract . An optimal emergency strategy under the disruptions is also given and an adjusted buy-back contract which can coordinate the supply chain is proposed.Finally, the flexibility quantity contract is discussed. A model is built up to discuss the flexibility quantity contract.
