考虑产品质量控制的供应链契约模型

Supply Chain Coordination Contract Model Considering Product Quality Control

针对考虑企业质量决策的供应链协调问题,构建了供应链质量管理非合作博弈模型,在模型中引入产品合格率及检测水平两变量.研究了在集中决策下实现供应链协调的最优产品合格率与最优检测水平;在分散决策下,证明了在考虑产品质量控制时不同契约在供应链协调中的有效性,结果表明收益共享契约、回购契约及售后担保三种契约均能实现供应链协调,产品合格率与检测水平对契约协调能力有着显著影响.并通过算例验证所得结论的有效性和可行性.

A non-cooperative game model for the supply chain quality management is built to solve the supply chain coordination problem with the product qualification ratio and inspection level introduced. The paper studies the optimal product qualification ratio and inspection level of supply chain enterprises under the centralized decision. In the decentralized decision,the effectiveness of different contracts in the supply chain coordination aiming at quality control is verified. Results show that the revenue sharing contract, the buyback contract and the after-sale guarantee contract all can achieve supply chain coordination,and that the product qualification ratio and the inspection level have a significant impact on the contracts＇ supply chain coordination. The numerical case demonstrates the effectiveness and feasibility of the proposed model.
