考虑生活垃圾可利用率的闭环供应链差别定价决策

基于可回收垃圾的可利用程度与消费者对其再制品的偏好性不同的实际情况,建立闭环供应链的差别定价模型,从而分析闭环供应链总利润随废品可利用率和消费者偏好的变化规律。结果发现,当再制品和残值单位总价值大于新产品的单位成本价格偏好时,总利润随着消费者偏好系数的增大而增大。但在分散决策情形下,会造成各企业节点之间效率的流失。据此,提出以集中决策下的均衡结果作为标准,建立了一种协调契约收益共享机制。最后通过算例分析,得到收益共享比例的具体取值范围,实现了供应链中各节点之间的有效协调。

Differential pricing decision of closed-loop supply chain considering domestic waste availability

Based on that for remanufactured products,recyclable waste availability is different from consumers’preference.The total profit of the closed-loop supply chain with waste products and consumer preferences availability has changes.In order to analyze the changes,this paper established a differential pricing model for a closed-loop supply chain.The results show that total profit increases as the consumer preference coefficient increases,when the total value of remanufactured and residual value units is greater than the unit cost price preference of new products.However,in the case of decentralized decision-making,it would cause a loss of efficiency between the nodes of each enterprise.So,it established a coordinated contract revenue sharing mechanism based on the equilibrium results under centralized decision-making.At last,through the numerical simulations to calculate specific value range of the revenue sharing ratio,it realizes the effective coordination between the nodes in the supply chain.
