摘　　要：针对包含供应商、制造商、零售商、顾客和回收处理商的闭环供应链,在多商品流和随机需求假设下,利用网络均衡理论,分析了每类决策者的行为,得到了基于变分不等式的闭环供应链均衡模型,并给出了经济解释。对补贴政策进行了灵敏度分析,实验表明:当补贴额增加时,回收率也相应增加;异质商品在销售和回收过程中都存在竞争。For a closed-loop supply chain consisting of suppliers,manufacturers,retailers,customers and recyclers,under the conditions of multi-commodity flow and stochastic demand,we develop a closed-loop supply chain network equilibrium model,and analyze the behavior of the various decision-makers by using network equilibrium theory and variational inequality.Then we present a sensitivity analysis on subsidies.The results show that the collection rate will increase with the growth of subsidies,and that heterogeneous products always compete in sale and recovery processes.
