铁路点外上线计划管理信息系统设计与开发

铁路点外上线作业是保证其正常运营必不可少的环节。当前采用的纸质作业形式，存在施工维修作业内容信息收集不完善、信息传递简单化、分层管理数据不清晰等问题，不利于后期的统计分析和管理。文章针对点外上线作业中存在的问题，结合实际现场作业流程，以数据库和网络技术为支撑，基于C/S模式，设计和开发了点外上线计划管理信息系统。系统通过设立工区级、队部级、公司级三级应用层次，实现了维修计划的层层提报、修改、审批、下达执行、信息反馈、数据查询等功能，提高了点外上线计划的管理质量。该系统已经在天津南环铁路有限公司维修公司（工务系统）得到试用，效果良好。

Management Information System for maintenance plans beyond schedules

The maintenance plans beyond schedules are necessary to keep the normal operation of the railway. The paper operation has some shortcomings, such as that the information of maintenance is not perfect, the information of transfer is simple, hierarchical management data is not clear, and so on. These problems are not conductive to statistical analysis and management. Aiming at the problem of maintenance plans beyond schedules, combining with the actual operation process, this article designed and developed a Management Information System for maintenance plans beyond schedules which was supported by the database and network technology, based on C/S model. The System was designed with three-level application, which is work area, headquarters of a team, the company. It implemented the functions of the maintenance plan of submission, modify, approval, order execution, feedback, data query, and etc., improved the quality of management. This System was applied in the Tianjin South Circle Railway Company. The application effect was good.
