探讨了不确定环境下单一供应商、制造商和零售商组成的三级供应链契约协调问题。分别建立了供应链集中、分散和契约协调最优决策模型。分析了基于收益共享契约的分散无协调和集中决策下供应链的期望利润。证明了通过收益共享和批发价格的组合契约可以使供应链实现帕累托改进。数值算例说明了契约协调的有效性。
The problem of contract coordination of three-level supply chain composed of a single supplier, manufacturer and retailer in uncertain environment is discussed. The optimal decision-making model of centralized, decentralized and contractual coordination in supply chain is established respectively. The expected profit of the supply chain under decentralized and uncoordinated and centralized decision-making based on revenue sharing contract is analyzed. It is proved that the supply chain can achieve Pareto improvement through the combination of revenue sharing and wholesale price. Numerical examples illustrate the effectiveness of contract coordination.
