全路列车运行图编制系统设计的研究

Research on Design of Train Diagram-Making System of Railways in China

提出全路列车运行图编制系统建设的远期目标和近期目标,设计了包括铁道部和铁路局2级层次的系统总体结构,并对系统的功能和实现技术进行了研究 给出了以铁路局和铁路分局数据库为基础,合并建立全路列车运行图数据库 并以区间作为基本数据描述单元,进行数据库设计和单双线合一的列车运行图编制思想和方法 针对系统研究的技术关键问题,如系统的数据组织及数据结构设计、编图算法求解及系统的人机交互功能设计等进行了介绍和探讨.

The shortand longterm goals of constructing the train diagrammaking system of railways in China are put forward. A general structure of this system based on the two levels of the Ministry of Railway and railway bureaus is proposed, and its functions and implementation approach are discussed. An idea of train diagrammaking is advanced. That is, the train diagram database of railways in China may be set up on the basis of railway bureaus' and subbureaus' databases, sections should be used as the basic description unit in the design of databases, and single and double track railways ought to be considered at the same time in train diagram making. In addition, the key techniques of the system design such as the organization of data, the design of data structure, the solution of diagrammaking algorithm and the design of manmachine interaction functions are discussed.
