三级物流服务供应链最优收益共享系数确定方法

Determination Method of the Optimal Revenue-Sharing Coefficient in Three-Echelon Logistics Service Supply Chain

为了精确确定供应链收益共享契约中的收益共享系数,考虑物流服务供应链中服务能力不可储存的特性,建立了以物流服务集成商为主导的Stackelberg主从博弈模型.结合收益共享契约机制,得到了收益共享系数的取值区间.引入公平熵函数描述利润分配公平原则,建立了在随机需求环境下可精确求出最优收益共享系数的三级物流服务供应链模型.算例结果表明:物流服务集成商和提供商的收益共享系数分别为0.840和0.848时,最大公平熵为0.999.

In order to determine the revenue-sharing coefficient of supply chain with a revenue-sharing contract,a Stackelberg game model with the logistics service integrator as a leader was built by taking the non-storage property of logistics service supply chain into consideration.On the basis of the revenue-sharing contract,the value range of the revenue-sharing coefficient was obtained.Then,a solution model for the optimal revenue-sharing coefficient in three-echelon logistics service supply chain was built in a stochastic demand environment,by introducing an equity entropy function to describe the equity principle of profit assignment.With this model,the optimal revenue-sharing coefficient can be found accurately.An example shows that when the revenue-sharing coefficient is 0.840 for the logistics service integrator and 0.848 for the logistics service provider the maximal equity entropy is 0.999.
