基于第3方逆向物流的闭环供应链模型及应用

Models of closed-loop supply chain with third-party reverse logistics and their applications

在价格敏感的随机需求量与回收努力敏感的随机回收量条件下,建立了基于第3方逆向物流服务提供商(3PRLP)从事物料回收的多级闭环供应链模型.设计了制造商与第3方之间的目标奖惩合同,讨论了分散闭环供应链系统中制造商为主方、销售商和第3方为从方的一主多从 Stackelberg 对策及集成闭环供应链的联合优化策略,并从供应链合同协调的角度进行了对比分析.最后结合上海宝钢公司废钢回收的实际运作情况进行了仿真计算与分析.

Assuming price-sensitive stochastic demands and effort-sensitive stochastic returns, a multi-echelon closed-loop supply chain with 3PRLP is established. A target rebate-punish contract between the manufacturer and the 3PRLP is designed. The closed-form analytic expressions for both united optimization strategies in cen- tralized closed-loop system and the one-leader-multiple-follower Stackelberg strategies in decentralized system are deduced, and comparisons are made from the viewpoint of contract coordination. Finally, according to the practice of Baosteel Companies, some simulation experiments are carried out to gain an insight into the impacts of reverse logistics activities on the practitioners operations and decisions.
