Under The Random Demand Supply Chain’s Optimization Strategy And Coordination Mechanism Research

Based on the hypothesis of the market demand existed random deviations and also was sensitive to the commodity price. This paper used the classic stackbelg model in Game Theory and the reverse induction theory to research the supply chain optimal strategies.First, this paper studied how to find the optimal strategy in the secondary supply chain system which was made of just one manufacture and one third-party logistics service providers.Second, this paper also studied how to find the optimal strategy in the Three-level supply chain system which was made of one supplier, one retailer and one third-party logistics service providers.Finally, according to the research of supply chain management coordination mechanism with third-party logistics service providers; we decided to use the revenue sharing coordination mechanism to help the supply chain get Pareto improvement.Through this paper we could get some conclusions as follows.(1) By a single manufacturer and single third-party logistics service providers in the secondary supply chain, and adding a retailer in supply chain after three cases, every enterprise’s profits after they all got their single object of max profit was less than their cooperative supply chain profits.(2) In the two supply chain and three supply chains, the local profit and overall profits were diminishing as the random deviations increased.(3) After introducing of revenue sharing coordination mechanism, the members of the supply chain can achieve both corporate profits and the overall optimal system profit.At last, we used the method of numerical analysis to illustrate the application of the model and revenue sharing mechanism.
