【摘要】 我国铁路在列车运行图的编制与管理中尚无运用于铁道部的全路列车运行图计算机软件系统 ,因此 ,加速研究“全路列车运行图信息系统”十分迫切。可先以铁路局或铁路分局为单位分散建立独立的数据库 ,然后再将它们有效地合并在一起 ,构成一个完整的全路列车运行图数据库。但仍需解决好系统的数据组织、数据结构设计、编图算法求解及系统的人机交互功能设计等问题。目前该软件系统开发已初步成型 ,试验表明 ,该系统在技术上是可行的。更多还原

【Abstract】 In the compilation and management of China railway train graph, there has not been a software system for system wise train graph of Railway Ministry. It is hence pressing to speed up the study on “system wise train graph information system”. It shall be feasible to create independently the databases in railway administrations or sub administrations, then to combine them effectively to compose a complete database for system wise train graph. However, it is still necessary to well resolve the problems such as the data organization of system, the design of data structure, solution of graph compilation calculation method and functional design of system man machine interaction, etc. At present the software system has reached its preliminary form and the test results proved its technical feasibility.更多还原
