基于政府环保补贴的再制造供应链均衡决策研究

Research on Remanufacturing Supply Chain Equilibrium Decision-Making Based on Government Environmental Subsidy

在市场竞争环境下,基于政府环保补贴政策研究多个再制造商间均衡决策问题,在政府环保补贴和市场竞争条件下,建立多个再制造商之间的博弈模型。通过变分不等式转化原优化问题,证明纳什均衡解是存在且唯一的,并运用欧拉算法和Matlab进行数值分析。算例结果显示,有效的补贴政策能促使再制造企业提高其产品环保等级并带来更多利润。

In the market competition environment,based on the government environmental protection subsidy policy,the equilibrium decision-making problem among multiple remanufacturers is studied.Under the government environmental protection subsidy and market competition conditions,a game model between multiple remanufacturers is established.The original optimization problem is transformed by variational inequality to prove that the Nash equilibrium solution exists and is unique,and the Euler algorithm and MATLAB are used for numerical analysis.The results of calculation examples show that effective subsidy policies can prompt remanufacturing companies to improve the environmental protection level of their products and bring more profits.
