考虑利润分配公平性的供应链激励模型

Supply Chain Incentive Model with Constraint of Profit Allocation Equity

本文基于回购契约建立了供应商对销售商的激励模型。模型以供应商的利润最大化为目标函数,约束条件除销售商的参与约束和激励相容约束外,还考虑了供应链利润分配的公平性。从供应链的角度来看,虽然该激励模型没有涉及供应链的协调问题,但该模型较好地体现出了供应链节点企业之间的合作关系。从算例分析可看出,随着供应链利润分配公平程度的提高,供应链的效率也在提高,供应链的利润与供应链协调时的利润非常接近。因此供应链的效率与供应链利润分配的公平性之间具有高度的一致性。

A supply chain incentive model was established based on buy back contract. The objective was to maximize the supplier＇ s expect profit. In this model, besides the constraints of the incentive compatibility and participation, the supply chain＇s profit allocation equity was considered. From the view of the whole supply chain, this model didn＇t discuss the supply chain＇s coordination, but this model better embodied the cooperative relationship between the supplier and the retailer. It can be seen from the numerical example that the efficiency of the supply chain increased with the increasing of the supply chain＇s profit allocation equity, and the supply chain＇s profit was very close to the supply chain＇ s profit obtained when the supply chain is coordinated. So, there exists high consistency between the supply chain＇ s efficiency and the supply chain＇s profit allocation equity.
