一种基于GIS的铁路设备维修路线规划方法

摘要

On researching management of railway equipment maintenance,summarizing the application experience of railway equipment maintenance management system based on GIS in a station.This paper discusses the path planning of railway equipment maintenance based on GIS.Main content of the work included the design of spatial database,the quality assurance of geographic information data,the development of GIS platform,the optimization of the classical Dijkstra algorithm and analysis of the efficiency of the optimized algorithm.Practical application shows that this method can solve the path planning problem of railway equipment maintenance,provide decision support for command and an effective way to shorten the cycle of railway equipment maintenance.%针对铁路设备的维修管理进行研究.在总结某站基于GIS的铁路设备维修管理系统应用经验的基础上,论述基于GIS的铁路设备维修路线的规划方法.其中包括空间数据库的设计、地理信息数据质量保证、地理信息平台的开发、对经典Dijkstra算法的优化及对优化后算法的效率分析等内容.实际应用表明该方法能够解决铁路设备维修路线规划问题,为铁路设备维修行车指挥提供决策支持,为提高铁路设备维修效率提供有效途径.
