Quantity Decisions Model And Contract Design In The Supply Chain Under Yield And Demand Uncertainty

Nowadays,many enterprises are confronted with yield uncertainty and demand uncertainty.This paper,taking the semiconductor industry as an example,discusses the uncertainty that the enterprises face and its impact on performance of supply chain.In the context of yield and demand uncertainty,this paper studies two-level and three-level supply chain models,analyzes supply chain inventory and production decisions,and discusses supply chain coordination mechanisms.In a two-echelon supply chain under vendor-managed inventory model,it is found that the universally used wholesale price mechanism can not make the supply chain achieve the performance of the integrated supply chain.The decentralized supply chain can not achieve the optimal profit of integration supply chain as supply chain members make decisions from their own perspective.And then the paper proposes option contract and subsidy contract,in order to enhance the performance of the supply chain.In a three-echelon supply chain,a single contract can not achieve an increase in supply chain performance because of the two transaction processes involved.This paper considers a contract combination.Different contract introduced in upstream and downstream of the supply chain succeeds to ameliorate the capability of the supply chain.In the two-level and three-level supply chain,this paper further analyzes the impact of contract parameters on the expected revenue of supply chain members.And the paper finds that the contract or contract combination can improve the performance of the supply chain and perfectly achieve a win-win situation and ensure that the expected returns of the members are not less than their existing profits without contract.
