摘要 列流图是展示通过某铁路区域的各类客货列流(列车流)的类别、径路和列车数量的直观图形表示形式,列流图包括铁路网络和列流线2部分。通过分析列流图的站场布局合理性、列流线的对称性及尽可能避免交叉等优化编制目标,提出编制列流图的左右、紧凑、分层、对称和分类5种排列原则,以及5种排列原则相冲突时应遵循的先后顺序,给出编制列流图的步骤,据此开发优化编制列流图的计算机软件系统。该系统采用图形输入铁路网络、列表输入列流,根据列流线排列原则和步骤自动生成列流图,并可导出CAD图形文件。对包括3个车站和7个方向的某区域铁路网络,运用该系统编制出具有60余条列流线的列流图。 A train flow diagram is a direct graphic form which shows the category, path and number of all kinds of passenger and freight train flow in railway network, which includes railway network and train flow line. By analyzing the criterions for drawing a diagram, such as the rationality of network distribution, the symmetry and crossing of train flow lines, we put forward five arrangement rules--left-right, compactness, delamination, symmetry and classification--and a method to arrange train flow diagram. We also developed software according to these principles and the method, in which the railway network is input graphically, train flows are input in a table, and the diagram can be created automatically and graphics files in AutoCAD form can be obtained. For a railway network with three stations and seven directions of a certain region, a train flow diagram which contains over 60 train flow lines is given by means of this software.
