基于GIS和多目标的生活垃圾运输路线优化研究

随着城市建设和规模的发展,人们生活水平日益提高,城市生活垃圾管理系统的改进与提高势在必行。为了探索生活最优运输路径,研究以北京市海淀区生活垃圾转运设施(五路居转运站)和处理设施(六里屯填埋场)为例,基于Arcgis9.2软件平台,利用最短路径搜索法和GIS(地理信息系统)中网络分析工具以及AHP(层次分析法),建立了可视化多目标运输体系,并搜索出不同目标(路线最短、时间最短、环境最优和综合加权)下生活垃圾最佳运输路径。该研究结果为海淀区生活垃圾运输系统提供可选优化路径和研究方法,从而为城市生活垃圾转运系统提高收运效率、减少运输过程中环境污染以及针对不同情况采用不同路线等问题提供理论指导和技术支持。

Route Optimization to Municipal Domestic Waste Based on GIS and Multi-objective

With the development of urban construction and scale as well as the increasing of people's living standard,it is imperative to change and improve the management of municipal solid waste(MSW) . Optimal routes of MSW transportation was discussed,taking Wu-luju refuse transfer facility and Liu-litun landfill located in Haidian District,Beijing as examples. Using Dijkstra arithmetic,spatial network analysis tool in GIS and AHP method,via Arcgis 9.2 software platform,a visual multi-objective transport system was built,which could find the optimal routes under different targets including the shortest line,the shortest time,the optimal environment and comprehensive evaluation. The study which provided optional optimal routes and research methods for MSW transport system could enhance the transfer efficiency,reduce probability of environmental pollution during transportation and select different routes according to different targets,which would provide theoretic instruction and technical support for various MSW transport system.
