面向供应链协调的利润分享契约及其响应方法研究

针对收入分享契约未能使供应链中的风险在成员企业之间有效分担的情况,提出了一种利润分享契约及其在需求价格弹性变动情况下的响应方法。按照该契约,供应商与零售商之间采用中间产品的单位成本作为结算价格,并在销售期末对供应链系统利润进行适当分配。当需求价格弹性发生变化时,需要调整利润分享契约参数以引导零售商的决策。研究表明,利润分享契约能够协调供应链;对市场需求变化的合理响应,能够促使双方接受新的协调契约,使供应链系统利润始终处于最优水平。仿真实例表明了利润分享契约及其响应方法的有效性。

Study on Profit Sharing Contract and Response Method for Supply Chain Coordination

A kind of profit sharing contract and its response method to variance of demand price flexibility have been designed by considering that the risk of supply chain has not been completely shared by the members with revenue sharing contract. According to the contract,the supplier transfers middle product to the retailer with price of unit cost,and shares the system profit properly. Parameters of the contract should be adjusted to induce the decision of the retailer. The research shows that,the profit sharing contract can coordinate the supply chain. Reasonable response to change of and the retailer accept the adjusted contract,which is helpful to optimize the profit of supply chain.Study of simulated case demonstrates the effectiveness of the profit sharing contract and the response method.
