考虑延伸售后保证服务的闭环供应链定价与协调

Price Decision-making and Coordination in a Closed-loop Supply Chain Model with Extended Warranty Service

在一个制造商和一个零售商构成的闭环供应链中,研究了延伸售后保证(Extended Warranty EW)不同提供模式下的供应链定价决策,比较了不同EW提供模式供应链的效率,设计了考虑满意度的收益共享契约协调供应链。研究结果表明:在服务成本相同的分散式决策环境下,零售商提供EW时,零售价较低,批发价也较低,同时销售量、回收率、EW价、各节点成员利润和总利润较高;无论是哪种EW提供模式,相较于集中式决策,分散决策零售价较高,而回收率、EW价和总利润较低。为实现供应链的协调,考虑到各成员的满意度,依据绝对偏离方法,设计收益共享契约。利用数值算例检验了理论结果。

In a closed-loop supply chain constituted by a manuiacturer and retailer, l tus study lnvesugates me pricing decision and the efficiency of the supply chain with different extended warranty （EW） modes. The revenue-sharing contract considering the satisfaction of participants is designed to coordinate the supply chain. The results show that with EW provided by the retailer, despite the same EW service cost and the decentralized deci- sion-making mode, the retail price and the wholesale price are lower, while higher are the sales, the recycling rate, the EW price, the profit of each member, and the total profit; No matter what mode of EW is provided, compared with centralized decision, the retail price is higher, while lower are the recycling rate, the EW price, and the profit of the while system when decentralized decision is implemented. Based on the absolute deviation approach, a revenue-sharing contract considering the satisfaction of participants is designed to coordinate the closed-loop supply chain. A numerical example is provided to verify the correctness of the conclusions.
