摘要
构建了绿色供应链低碳共生演化的概念模型,揭示了绿色供应链自适应系统动态演化控制机理;用碳足迹来分析碳排放对供应链总成本的影响,引入不同市场的响应时间变量,考虑响应时间对供应链销售收入的影响;借助罚函数系数来平衡成本、响应时间、碳排放三者的相互制约关系,将多目标优化问题转化为单目标优化,建立了绿色供应链网络设计决策模型,使整个网络在环境质量和经济效益的效率边界实现Pareto最优;最后通过数值分析验证了模型的有效性,为绿色供应链网络设计提供辅助决策方案,旨在促进整个供应链的可持续发展。
A conceptual model of low-carbon symbiotic evolution is established,and the model reveals dynamic evolution mechanism of adaptive system for green supply chain.The influence of carbon emissions is evaluated on supply chains’total cost using carbon footprint,by introducing difference market response-time variables to consider the influences of the re-sponse time on the sale income of supply chain.Penalty function coefficient is introduced to balance cost,response time and carbon footprint,which converts the multi-objective optimization problem to a single-objective one.A network optimization model is developed to balance the three targets of supply chain profitability,service level and environmental protection.An example is offered as proof of this model’s effectiveness,serving as a supplementary solution to optimization design of green supply chain network.
