废旧家电逆向物流网络模型优化与实证研究

Optimization and Empirical Research on Reverse Logistics Network Model for Waste Household Appliances

基于废旧家电数量大、回收价值高的特点,研究了废旧家电逆向物流专业网络的社会价值与构建重要性,将回收运输路径、节点设施建设成本以及相关政策倾斜下的家电处理补贴考虑到废旧家电回收网络中,构建了包括回收点、储存点、处理点和分销市场的四级网络模型,利用混合整数线性规划建立了以最小构建成本为总目标的数学模型,再结合0-1变量参数约束,借助计算机软件LINGO解决网络中节点选择和流量配置问题.研究中利用河南省地区废旧家电相关数据进行验证,证明逆向物流网络模型优化后更具有强关联性.

Based on the characteristics of large number of waste household appliances and high recycling value,the study highlights the social value and importance of constructing a professional network of reverse logistics for waste household appliances,takes into account the recycling transportation path,node facility construction cost,and home appliance disposal subsidies under relevant policy inclination into the waste household appliance recycling network,constructs a four-level network model including recycling points,storage points,disposal points and distribution markets,and uses mixed integer.A mathematical model with minimum construction cost as the overall objective is established by linear programming,and then the node selection and flow configuration problems in the network are solved by combining 0-1 variable parameter constraints with the computer software LINGO.In the study,the data related to waste household appliances in Henan Province were used for validation,which proved that the reverse logistics network model is more strongly correlated after optimization.
