基于改进重心法的校园快递服务中心选址研究

Research on Campus Express Service Center Location Selection Based on Improved Gravity Center Method

以西北大学长安校区为例,利用AHP法构建选址评价指标体系;结合实地调研数据完成空间数据采集,借助ArcGIS软件对数据进行矢量化处理,对校园快递服务中心可选区域中的建筑物和道路进行地理配准和空间校正;利用栅格计算器得到最优选址范围图,结果显示预选范围主要分布于宿舍区,与AHP法的结果一致,且包含了重心法的位置结果。在聚类分析的基础上,通过GIS平台实现了Dijkstra算法;通过改进的重心法求解坐标,得到西北大学长安校区集中式校园快递的最佳选址。结果表明,将多维度分析与GIS相结合,在改进的重心法分析下能使选址结果更加科学、适用性更强。

Taking Northwest University Chang,an Campus as an example,AHP method was used to construct the site selection evaluation index system.Combined with field survey data to complete the spatial data collection,ArcGIS was used to vectorize the data for geographical registra-tion and spatial correction of buildings and roads in the campus express service center optional area.The results show that the pre-selected areas are mainly distributed in the dormitory area,which is consistent with the analytic hierarchy process and includes the location results of the gravi-ty center method.Based on cluster analysis,Dijkstra algorithm was achieved through GIS platform and coordinates were solved by improved gravity method.The optimal centralized campus express location in Chang,an campus of Northwest University was obtained.The research and analysis results show that the combination of multi-dimensional analysis and GIS can make site selection results more scientific and applicable with the improved gravity center analysis.
