零售商具有风险厌恶偏好下的易逝品供应链协调分析

Analysis of Perishable Product Supply Chain Coordination with Risk-aversive Retailer

在随机市场需求受销售努力水平影响的前提下,研究了由一个风险中性的制造商和一个具有风险厌恶型的零售商组成的两级易逝品供应链的协调问题;通过模型分析指出单纯的回购契约无法实现供应链协调,而基于回馈与惩罚策略下的回购契约能够实现供应链协调,给出了供应链协调下的模型优化方法;然后分析了风险偏好对供应链成员决策的影响,结果表明:零售商风险厌恶程度与最优订购量成负关系变动,而与零售商利润及供应链最优系统利润成正关系变动。最后进行了数值验证。

In this paper, on the premise that the market demand was stochastic and under the influence of the sales effort level, we studied the coordination of a two-echelon perishable product supply chain composed by a risk-neutral producer and a risk-aversive retailer. First, through analyzing the model, we pointed out that simply by a buyback contract, we could not coordinate the supply chain and that through a buyback contract based on the feedback and penalty strategy, we could. Then we presented the optimization model of the supply chain, analyzed the influence of the risk preference on the decision-making of the supply chain members, and at the end, through a numerical example, proved the correctness of the model.
