销售努力与价格干扰下的回购契约模型分析

摘要

In this paper, on the premise of the verifiable sales efforts, we studied the buyback contract coordination problem where the market demand was influenced simultaneously by retailing price and sales effort level. First we presented the optimal ordering volume, efforts level and retailing price of the supply chain system under centralized decision-making, then explained why the traditional buyback contract malfunctioned under distributive decision-making, then on such basis introduced the mixed buyback contract that introduced effort cost apportionment and price ceiling to realize supply chain coordination, and at the end, through a numerical example, validated the model established.%实现供应链协调的一个重要方法就是供应链契约，以一个两阶段存货式生产供应链系统为背景，研究了在销售努力可以核实的前提下，零售价格与销售努力水平同时影响市场需求时的回购契约协调问题。首先在集中决策下给出系统最优的订货量、努力水平和零售价格，然后解释了分散决策下传统回购契约失灵的原因。为此，引入基于努力成本共担与最高限价的混合回购契约，实现了供应链协调。最后，通过数值算例对模型进行了检验。
