风险约束下退货合同对供应链的协调性分析

Analysis of return policy for coordinating supply chain under downside risk constraints

在零售商在风险约束下,分析了退货策略对单周期供应链的协调性.首先运用报童库存模型建立了供应链决策模型,然后运用解析法对满足零售商下游风险约束下的零售商决策进行了优化分析.对于供应商的决策,采用数值分析方法分析了零售商下游风险对其决策的影响.研究表明,在风险约束制约下,零售商和供应商的期望利润都有所减少,退货合同的协调性较无风险约束情况下弱.最后,对未来的研究方向给出了建议.

This paper analyzes the coordination of return policy for single-period supply chain consisting of one supplier and one retailer, the latter is constrained by downside risk. We model the decision problems with newsboy model and then analytically derive the optimal policies for the retailer. For the optimal decisions of supplier, we use the numerical method to analyze the effect of retailer downside risk on the decision variables and the profit of the supplier. Compared with the case of no risk constraints, the study has shown that the expected profits of both members of supply chain have been reduced under the control of the return policy, which means the return policy can not coordinate the supply chain under retailer downside risk constraint. We also give with a discussion of contract implementation issues and future research.
