生产成本扰动下差别定价闭环供应链的应对策略及协调

Dealing strategies and coordination of closed-loop supply chain with differential price under production cost disruptions

针对一个考虑新产品和再造品差别定价的制造商回收闭环供应链,在突发事件干扰两类产品生产成本发生扰动的情况下,研究了集中式决策闭环供应链的应对策略,以及设计可协调突发事件干扰下分散式决策闭环供应链的数量折扣契约问题。研究表明:突发事件发生后,集中式决策闭环供应链的稳定环境下新产品和再造品最优决策的调整方式不仅与两类产品生产成本发生扰动的程度相关,还与两类产品之间的相互替代系数相关;改进的数量折扣契约可通过使系统成员共担突发事件干扰的风险实现分散式决策闭环供应链的协调。通过数值算例验证了所得结论的正确性。

Aimming at a manufacturer collecting Closed-Loop Supply Chain(CLSC)with differential price between new and remanufactured products,the dealing strategies of centralized CLSC and the coordination of decentralized CLSC were studied by considering the situation that production costs of two products were disrupted.The results show that the adjustment directions of normal environment optimal decisions of new and remanufactured products were not only related to the disrupting degree of production cost for the centralized CLSC,but also to substitute coefficient of the two products.The improved quantity discount contract could coordinate the decentralized CLSC under disruptions.A numerical example was given to examine the theoretical results.
