考虑消费者不确定偏好的闭环供应链定价与协调

Pricing and Coordination of Closed-Loop Supply Chain Considering Consumers' Uncertain Preferences

在闭环供应链受到广泛重视的背景下,充分考虑消费者对不同销售渠道的敏感程度和回收渠道的回收意愿,建立了由单个制造商、单个零售商和单个回收商组成的闭环供应链模型。首先,通过分散和集中决策模型,得出消费者的销售渠道的敏感系数和回收意愿对供应链决策、利润和回收率的影响程度。然后,用收入费用共享合同和两部定价法契约实现了闭环供应链的完美协调。最后,用数值仿真对渠道的敏感程度和回收意愿进行了灵敏度分析,探讨了分散和集中决策模型下最优决策的变化情况。

Under the background of wide attention in the closed-loop supply chain, fully considering the de- gree of sensitivity in different sales channels and recycle willingness in recycle channel of consumers, this paper established a model of closed-loop supply chain consisted of a single manufacture, a single retailer and a single recycling provider. First of all, through decentralized and centralized decision making model, it gets the influence degree of consumers sensitivity coefficient in sales channels and recycling willingness to supply chain decisions, profit and recovery rate. Then, using revenue-and-expense sharing contract and two-part tariffs, it realizes the perfect coordination of closed-loop supply chain, Finally,using numerical simulation, this paper takes sensitivity analysis to the sensitivity degree of sales channels and recycling willingness, and it also discusses the changes of the optimal decision based on the decentralized and centralized decision model.
