关于我国高速铁路列车运行图缓冲时间的研究

本文借鉴既有研究成果,从定量的角度研究了高速铁路列车运行图缓冲时间的优化取值问题。首先对缓冲时间的定义及分类等基本理论进行了总结,然后以某一列车初始晚点对后续列车造成的后效晚点时间总和为目标函数,研究这一总时间与缓冲时间取值的函数变化趋势,得出了缓冲时间在不同情况下的合理取值建议和方法。

Study on High-speed Train Diagram Buffer Time of China

Excerpting the previous research results, this thesis studied the issues of optimizing and valuing the buffer time of high-speed train diagram from a quantitative view. First, the thesis summarized the basic theories, such as certain definitions and classifications of buffer time. Furthermore, the variation tendency of the total time and the valuation of buffer time were discussed, taking the total time delay from an initial late train to influencing the next train as a target function. Last, the suggestions and methods of the appropriate buffer time under different conditions were presented in this paper.
