【摘要】：随着人们对所处生活环境要求的不断提升以及经济全球化、社会信息化的发展，建设一个资源节约型和环境友好型社会的构想引起了人们对于逆向物流，尤其是对基于回收再制造的闭环供应链的广泛关注。对于废弃产品的回收再制造也越来越引起企业的重视。企业的这种行为一方面是迫于相关环保政策的压力，，另一方面是企业可以通过这样的回收再制造过程赢得良好的环保声誉，同时可以降低自身的生产成本，提高企业利润。因此，对于闭环供应链的研究具有理论和实际双重意义。虽然近年来国内外对于闭环供应链的研究越来越多，但是研究多是基于新产品与再制造产品之间无差异，回收产品无差异，零售商如实汇报自身的回收成本。然而实际情况下，即便在技术上可以达到再制造产品的性能、质量和新产品相同，但是消费者的感受和认知不同也会对两种产品的认可度存在差异，而回收的产品由于废旧程度不同，不可能都进行再制造处理，另外，企业受利益驱使可能会谎报自身成本信息以求获得更多的利润，存在信息不对称的情况。基于此，本文从实际情况出发，假设闭环供应链系统由单一制造商、单一零售商和消费者组成，并且回收过程由零售商负责完成，假设新产品和再制造产品存在一定替代关系，批发和零售价格不同，而且回收价格也不同。通过构建模型给出了对称信息和不对称信息条件下系统各成员的定价策略，并进一步比较相应的利润，引入了收益共享契约来对闭环供应链系统进行协调。又通过具体算例验证了模型的正确性，并分析了新产品和再制造产品替代关系对利润的影响，进一步指出了如何对闭环供应链系统进行协调。
[Abstract]:With the increasing demands of the living environment and the development of economic globalization and social information, the idea of building a resource-saving and environment-friendly society has caused people to reverse logistics. In particular, the close-loop supply chain based on recycling and re-manufacturing is widely concerned. Enterprises pay more and more attention to recycling and remanufacturing of waste products. On the one hand, the behavior of enterprises is under pressure from relevant environmental protection policies, on the other hand, enterprises can gain good reputation for environmental protection through such recycling and remanufacturing processes, at the same time, they can reduce their own production costs and increase their profits. Therefore, the study of closed-loop supply chain has both theoretical and practical significance. Although there are more and more researches on closed-loop supply chain at home and abroad in recent years, most of the studies are based on the fact that there is no difference between new products and remanufactured products, and there is no difference in recycled products. Retailers report their recovery costs truthfully. However, in practice, even if the performance and quality of the remanufactured product can be achieved technically, the consumer's perception and perception of the two products will be different from that of the new product. Because of the different degree of waste, it is impossible for the recycled products to be remanufactured. In addition, enterprises driven by interests may lie about their own cost information in order to obtain more profits, and there is information asymmetry. Based on this, this paper assumes that the closed-loop supply chain system is composed of a single manufacturer, a single retailer and a consumer, and the recycling process is completed by the retailer, assuming that there is a certain substitution relationship between the new product and the remanufactured product. Wholesale and retail prices differ, and recovery prices vary. By constructing a model, the pricing strategies of each member of the system under the condition of symmetric information and asymmetric information are given, and the corresponding profits are further compared. A revenue-sharing contract is introduced to coordinate the closed-loop supply chain system. The correctness of the model is verified by an example, and the influence of the substitution relationship between the new product and the remanufactured product on the profit is analyzed, and how to coordinate the closed-loop supply chain system is further pointed out.
