Research on Multi-Period Closed-Loop Supply Chain Network Equilibrium Based on Consumers' Preference for Products

This paper comprehensively analyzes the impact of consumer preference for products in a multi-period closed-loop supply chain network (CLSCN) equilibrium. This paper is based on the multi-period CLSCN equilibrium model of remanufacturers' recoveries and multiple planning periods. The consumer preference for products at multiple planning periods are respectively divided into dynamic and static conditions. Moreover, the intervention of government is considered. Meanwhile, the variational inequalities are employed to separately depict the optimal behaviors and equilibrium conditions of the supply chain network. The results show that when the consumer preference for new products is static, the impact of consumer preference for new products has a significant impact on the multi-period CLSCN. If consumer preference for new products is dynamic, at the preliminary planning period, the impact of consumer preference for new products on the multi-period CLSCN will be better defined.
