供应链回购合同的权重效用利润函数分析

Analysis on the Weighted Utility Profit Function of Buy-Back Contract in Supply Chain

引入供应链权重效用利润概念,研究在回购合同协调供应链前提下权重效用利润相对于传统效用利润能否增加的问题.在权重效用利润函数最大值问题的研究基础上,证明了可以通过修正相应的合同参数形成新的协调性回购合同使得利润增加,并给出相应的的合同条款并给出具体数值例子验证结论.

In this paper,the concept of weighted utility profit in supply chain was introduced,and the problem whether the weighted utility profit increase or not relative to traditional profit of buy-back contract was studied in the premise the contract coordinating supply chain.On the basement of research on the maximization of weighted profit utility function,a new buy-back contract was formed which not only coordinating supply chain but also increasing profit by modifying relative parameters in supply chain.Lastly,a numerical example was performed to support above conclusion.
