摘　　要：针对一个实施VM I(供应商管理库存)的两级供应链,市场需求受供应商和零售商双重努力影响的问题,建立了基于协作关系的库存和努力水平决策模型。通过分析得出在分散决策下供应商选择的库存水平和零售商选择的努力水平均低于集中决策下的最优水平,供应链效率也较低。设计了一个成本分摊契约协调供应链。结果表明,该契约能将供应商和零售商紧密地联系在一起,且通过供应商和零售商的共同努力能获得比分散式决策下更大的利润。The coordination problem for a two-stage supply chain composed of a supplier and a retailer is considered in this paper.It is a vendor managed inventory（VMI） supply chain and the demands are influenced by both the supplier and retailer＇s efforts.Based on collaborative partnerships with inventory-level decision and effort-decision,a mathematical model is developed.With this model,analysis is carried out.It shows that,under decentralized decision-making,both the inventory level and effort level of the supplier and retailer are below the optimal ones obtained under the centralized decision-making.In other words,the efficiency of supply chain under the decentralized decision-making is worse than that under the centralized one.To solve this problem,a cost sharing contract is presented to coordinate the decentralized supply chain.Analysis shows that such a contract can make both sides in the supply chain collaborative such that more profit can be gained for both sides than that obtained without coordination.
