摘要
在由单个供应商和单个零售商组成的供应链中,零售商由于资金短缺或风险规避不能达到系统的最优订货量,因此需要采取一些措施使得供应链节点企业间相互合作来实现供应链的协调。本文针对需求随机且供应链节点企业存在缺货惩罚的情况,通过设计基于商业信用(即供应商允许零售商延期支付货款)的完全回购契约来促进零售商提高订购量,以实现供应链系统达到最优利润,分析给出了该契约下的最优订货量和批发价格;在此基础上,为了合理分配供应链系统的总利润,建立了回购与收入共享联合契约模型,发现通过共享系数的变动能够实现供应链系统协调和渠道成员双赢。
This paper considers a supply chain consisting of a supplier and a retailer.Because of the retailer＇s funding constraints or risk aversion,the system cannot achieve the optimal order quantity,so it needs to take some measures to make the enterprises mutually cooperate to achieve coordination of the supply chain.Under a random demand and existing punishment of goods shortage,a model of entirely buy-back is designed to improve the order quantity of the retailer based on trade credit（i.e.suppliers allow retailers to delay payment of the loan）.This model makes the supply chain system achieve the optimized profit.And the optimized order quantity and the wholesale price based on the contract is given.Furthermore,a revenue-sharing mechanism based on the model for distributing the profit and improving the operational performance of entire supply chain is analyzed.The parties of supply chain can achieve coordination through the given parameters.
