构建了由一个直接从事再制造活动的制造商和一个零售商组成的闭环供应链系统。假设产品的需求与产品的销售价格、产品的质量水平、制造商的回收努力和零售商的销售努力成线性关系,运用博弈论分析了闭环供应链系统在集中决策和3种分散决策下的最优策略。研究发现:闭环供应链系统在VN权力结构下的利润是3种分散决策模型中最大的,在MS权力结构下的利润是最小的。运用两部定价契约实现了不同权力结构下闭环供应链的协调。最后通过数值仿真验证了模型的合理性和不同权力结构下协调合同的有效性,并对主要的参数进行了敏感性分析。
A closed-loop supply chain system consisting of a manufacturer and a retailer who are directly involved in remanufacturing activities is constructed. Assuming that the demand of the product is linear with the selling price of the product, the quality level of the product, the recycling efforts of the manufacturer and the sales efforts of retailers, the game theory is used to analyze the relationship between the closed-loop supply chain system and the three kinds of decentralized decision making Excellent strategy. The results show that the profit of closed-loop supply chain system under VN power structure is the largest among the three kinds of decentralized decision-making models, and the profit under MS power structure is the smallest. Using two pricing contracts to achieve the coordination of closed-loop supply chain under different power structures. At last, the rationality of the model and the validity of the coordination contract under different power structures are verified by numerical simulation, and the sensitivity analysis of the main parameters is carried out.
