基于改进线性分成契约的逆向供应链协调机制

Study on reverse supply chain coordination mechanism based on improved linear revenue-sharing contract

提高废旧产品的回收效率,实现逆向供应链协调,是逆向供应链能够得以高效运营的重要保证.文章针对单个再制造商和单个回收商构成的二级逆向供应链,利用博弈论和激励机制理论,分析了传统线性分成契约的激励不足问题,并提出新的有协调作用的契约形式.在上述基础上,本文对回收商成本类型为对称信息和不对称信息下的契约具体形式做了进一步讨论,并通过数值仿真分析了参数变化对协调机制的影响,所得结论对废旧产品回收供应链的运营实践有很好的指导意义.

To improve the recycling efficiency of end-of-life product is an important way to ensure that the reverse supply chain operate efficiently. A two-stage reverse supply chain consisting of one re-manufacturer and one recycler was considered in this paper. The paper analyzed the insufficient incentive problem in traditional revenue-sharing contract, and then put forward a new contract with coordination function by using game theory and incentive theory. The form of the contract was further discussed respectively in the situation of symmetric information and asymmetric information about recyclers＇ cost type. The effects of certain parameters on coordination mechanism were illustrated with a numerical simulation. The conclusion in this paper will be valuable to the operation of reverse supply chain.
