摘要
本文在分析编组站现车管理信息系统流程图的基础上,提出了合理组织编组站信息的几种数据库模式和用状态转换法进行编组站数据规范化的方法。这种方法在编组站管理信息系统设计中能较好的解决时/空关系,对减少系统投资和提高系统的工作效率有现实意义。
On the basis of analyzing the flow chart of Management Information System of Railway Marshalling Yard, in this paper are presented several data base modes for the reasonable organization of Railway Marshalling Yard information and the data normalization method for Railway Marshalling Yard by way of Status Transform. This method has nicely solved the problem of the ralationship between time and space in designing Management System of Railway Marshalling Yard and it is of realistic importance in reducing system investment and increasing working efficiency.
