列车运行图可调整度评价系统研究

A System for Evaluation of Train Diagram Elasticity

在详细分析了列车运行图缓冲时间的大小及其分布规律对列车晚点传播影响的基础上，通过建立列车运行图调整系统，对给定晚点程度的列车进行模拟调整，从而计算出列车晚点恢复率（或增晚时间）、晚点传播区大小、连带晚点时间和关键列车运行线等指标来达到对列车运行图可调整程度优劣评判的目的。

Based on the analyses of the influences of buffer time and its distribution pattern on train delay propagation in a given train diagram, an adjustment system for train diagram is proposed. The recovery time or extra delayed time of a delayed train and the spreading area of train delay are calculated with the system, so that the key train lines can be find out. The elasticity of the diagram, therefore, can be evaluated.
