摘　　要：研究了随机市场需求下由制造商、分销商和零售商组成的三级供应链的协调问题.通过分散式无协调状态和集中决策状态下的供应链收益比较,采用数量折扣和价格补贴双契约机制,设计了Qd-Ps联合契约模型.并用算例证明了通过合理范围内的参数设置和取值,可实现供应链节点企业的利润共享,并促进供应链系统的有效协调.The coordination problem of three-level supply chain under stochastic demand is studied, which consists of the manufacturer,distributor and retailer. According the compari- son of the supply chain revenue between decentralized with uncoordinated state and central- ized decision state, the Qd-Ps combined contracts model is designed with dual contract mechanism by using Quantity discounts and price subsidies. A numerical example was used to prove the reasonable parameter values can achieve the goal of profit-sharing among the node enterprises in supply chain, and it can also promote the effective coordination of supply chain.
