摘要
针对电子废弃物逆向物流网络特点,从整体逆向物流选址优化角度,分析并确定了网络成本最优化混合整数线性规划(Mixed-Integer Linear Programming,MILP)模型.考虑废弃物的回收成本、处理成本、处理规模、经处理后碎片的销售收入、政府补贴,以及由于专业分工所带来的在不同拆解处理厂间及不同粉碎处理厂间的物料流动,可以灵活支持子网络内各个企业间物流活动.此外模型支持多种类型的电子废弃物的输入,以及经处理后产生的多种不同的物料碎片的输出,帮助优化电子废弃物逆向物流网络中的选址和物料分配等问题.
Based on the analysis of the electronic waste （E-waste） reverse logistics network,an optimization model of E-waste reverse logistics network site is proposed. This model has cost minimization as its objective from the overall perspective of reverse logistics. The factors considered in the model include the cost of collection, disassembly and treatment, processing capacity, sales income from material fractions after disassembly, as well as recycling subsidy. The model considers specialized facilities as sub-networks, which can support logistics activity flexibly. At the same time, input of the network can be multiple types of E-wastes and the output could be different material fractions including valuable and hazardous substances. The proposed optimization model can help optimize facility location decision and the material flows in the network.
