研究了多周期规划视野下考虑产品生命周期和碳排放约束的闭环供应链网络均衡问题。闭环供应链网络由供应商层、制造商层、零售商层和需求市场层组成，制造商直接从需求市场收集旧产品。引入产品生命周期来表示制造和再制造的最大次数，并通过库存转移来描述相邻周期之间的关系。利用变分不等式和互补理论，对所有参与者的最优行为进行建模，进而建立闭环供应链网络均衡模型。模型的求解采用修正的固定步长的项目收缩算法。通过算例计算分析了最优平衡结果。分析了回收率、再制造转化率、产品寿命和碳排放总量限制对平衡状态的影响。最后，本文提出了一些管理学的见解，为企业家和政府官员提供决策支持沿着，并对未来的研究提出了一些启示。
This paper studies a closed-loop supply chain network equilibrium problem in multiperiod planning horizons with consideration of product lifetime and carbon emission constraints. The closed-loop supply chain network consists of suppliers tier, manufacturer tier, retailers tier, and demand markets tier, in which the manufacturers collect used products from the demand markets directly. Product lifetime is introduced to denote the maximum times of manufacturing and remanufacturing, and the relation between adjacent periods is described by inventory transfer. By variational inequalities and complementary theory, the optimal behaviors of all the players are modeled, and, in turn, the governing closed-loop supply chain network equilibrium model is established. The model is solved by modified project contraction algorithm with fixed step. Optimal equilibrium results are computed and analyzed through numerical examples. The impacts of collection rate, remanufacturing conversion rate, product lifetime, and carbon emission cap on equilibrium states are analyzed. Finally, several managerial insights are given to provide decision support for entrepreneurs and government official along with some inspirations for future research.
