在随机需求条件下研究了由多个相互竞争的供应商、制造商、零售商和消费市场组成,且零售商具有风险规避特性的再制造闭环供应链网络均衡问题.通过对不同决策层级最优化行为的分析,分别得到各层级和整个供应链网络实现均衡的条件,并建立相关的变分不等式模型.运用拟牛顿算法对变分不等式进行求解,通过仿真分析了随机再制造率和零售商的风险规避程度对网络成员最优行为和闭环供应链网络均衡的影响.
Under the condition of stochastic demand, this paper studies the equilibrium problem of remanufactured closed-loop supply chain network, which consists of multiple competing suppliers, manufacturers, retailers and consumer markets, and the retailer has risk-aversion characteristics. By optimizing the different decision-making levels Behavior, the conditions for achieving equilibrium at all levels and the entire supply chain network are obtained respectively, and the related variational inequality models are established.The variational inequalities are solved by using the Quasi-Newton algorithm.The random remanufacturing rates and the retailers’ The Effect of Risk Aversion on the Optimal Behavior of Network Members and the Equilibrium of Closed-loop Supply Chain Networks.
