摘要
针对目前大部分应急资源调度管理系统反应慢、效率低、步骤多等问题,采用B/S三层架构,使用WebGIS开发技术,SuperMap SDX+空间数据库技术以及最短路径算法Dijkstra,设计了应急资源调度管理系统.系统将资源储备点、中间配送点和受灾地抽象为一个个的节点,将整个的资源调度路线看做是网络图中的路段,将它们组织成一个空间的网络交通图,使调度的图表和表格在GIS中通过空间网络图进行表达.测试结果表明,该系统功能多样、性能稳定,提高了物资调度决策的可视化程度和直观性,达到了预期的目的.
Aiming at the problems of the most of the emergency resource scheduling management system at the present such as response slow,low efficiency,step overstaff and so on,a GIS-based emergency resource scheduling management system was designed. The system used B /S three-tier architecture,WebGIS development techniques,SuperMap SDX ＋ spatial database technology and the shortest path algorithm Dijkstra to design. The system abstracted resource reserves points,intermediate distribution points and the distribution of the affected land for each point,and the entire route was seen as a resource scheduling network diagram sections,basing it to organize them into a space network traffic map,making scheduling charts and tables in the GIS for expression through space network diagram. The test results showed that the system was versatile,stable in performance,which improved the visualization and intuition of material scheduling decisions to achieve the desired goal.
