基于异质消费群体的生态供应链网络均衡模型

Ecological Supply Chain Network Equilibrium Model in a Heterogeneous Market

文章针对不同消费者对新产品、再制造产品存在效用异质性的情况,构建了一个由制造商和消费者市场组成的两层生态供应链超网络模型,优化目标为经济效益最大化、环境影响和风险最小化。考虑环境规制及产品的可再造比例对整个供应链绩效的影响,利用网络均衡理论描述不同主体的独立行为和主体之间、产品之间相互影响的竞争行为。数据分析结果表明,系统整体效益以及企业对产品可再造比例的选择很大程度上取决于产品创新效率和政府补贴方式。

A two-echelon ecological supply chain model that consists of multiple manufacturers and markets is developed with the multicriteria decision-making, which includes the maximization of profit, the minimization of Waste emission, and the minimization .of risk. In terms that consumers have different preference to new product and remanufactured product, the independent behaviors of different decision-makers, as well as the competitive behaviors of interacted decision-makers and products are described with variational inequities considering the effects of environmental regulations and of the product on the performance of the total supply chain. Results of numerical simulation show that the selection of remanufacturable rate for the manufacturers would be effected greatly by the product innovation efficiency and the mode of allocating subsidies for the government.
