地震灾害应急物流配送系统模型优化方法研究

为合理选择应急物流配送中心地址，提高应急管理能力，基于地震灾害风险评价数据，通过ArcGIS平台形成Voronoi图，可视化表达地震应急准备分区方案并进行应急物流中心预选址；在考虑需求权重情况下，构建应急物流配送中心优化选址模型，通过LINGO软件编程求解得出基于震灾应急准备分区的应急物流配送中心选址方案，并以A市为例，通过与传统行政区划建设方案进行对比，验证本文选址方案的有效性。研究结果表明:本文选址优化模型综合考虑各方面因素，使服务里程总量减少31.39%，单位服务量提高30.61%，验证选址方案的配送效率与公平性。

Study on model optimization method of emergency logistics distribution system in earthquake disaster

In order to reasonably select the address of emergency logistics distribution center and improve the ability of emergency management,Voronoi diagram was formed based on the seismic risk assessment data by ArcGIS platform,visualizing the zoning scheme of earthquake emergency preparation and pre-selecting the location of emergency logistics center,constructing the optimal location model of emergency logistics distribution center under the consideration of the weight of demand,based on the LINGO software,the location scheme of the emergency logistics distribution center based on the Earthquake Emergency Preparedness Subarea was obtained,and the A as an example was compared with the logistics facility scheme built by the traditional administrative territorial entity.The results show that the model can reduce the total service mileage by 31.39% and increase the unit service volume by 30.61%,and verify the efficiency and fairness of the location scheme.
