基于低碳理念的多目标闭环供应链网络设计

针对低碳环境下的供应链网络设计，研究具有供应商、制造商、消费者、配送中心、回收中心及处理中心的多层级闭环供应链网络。考虑网络设施约束、碳排放、顾客服务等因素的影响，以网络运营成本、碳排放成本和顾客需求响应时间成本为目标建立多目标规划模型，解决网络内设施建设、选址、设施间流量分配等网络资源优化配置问题。利用Lingo11.0软件对模型求解，通过算例分析设施能力限制、碳税税率以及时间延迟成本对设施建设方式和网络成本的影响，为企业提供决策支持并在生产实践中发挥指导作用。

Optimization of Multi-objective Closed-loop Supply Chain Network Based on Low Carbon Concept

Aiming at the multi-echelon supply chain network design under the background of low carbon, a multi echelon closed-loop supply chain network with suppliers, manufacturers, consumers, distribution centers, recycling centers and disposal centers is under study. By considering the factors about network infrastructure capacity constraints such objectives as carbon emission, customer service and others, network operating costs, carbon emission costs and customer demand response time costs, a multi objective programming model is established to solve the problem of network resource optimization configuration, such as the facility construction within the network, location and traffic facilities distribution. Lingo 11.0 software is used to solve the model, analysing facility capacity constraints, carbon tax, time delay affecting the cost of facility construction methods and network costs by a numerical example, which provides decision support for the enterprise and can play a guiding role in the production practice. 〖WT5HZ〗Key words： 〖WTBZ〗
