列车运行图缓冲时间合理设置研究

The Train Running Buffer Time Reasonable Analysis and Research

以定量为基础,以如何在铁路列车运行图中设置合理的缓冲时间为目标,首先通过准确定义、合理分类缓冲时间,然后再以后效晚点时间总和作为目标函数,研究不同情况下,当前行列车产生源晚点时,对后行列车造成后效晚点下的总时间与缓冲时间的关系式变化趋势。通过寻找临界点分析相应的取值范围,得出最终的合理缓冲时间取值。通过设置合理的缓冲时间能使列车运行图的利用率得到有效提升,减少晚点列车。

In the existing data study,on the basis of quantitative,how to train on the railway running diagram set reasonable target buffer time.First by definition,the reasonable classification buffer time accurately,and then later combined effect late time as objective function,the different situation,the current line train source,late on the train after effect caused by the late after the total time and the relation between the buffer time trends.By looking for critical analysis of the corresponding scope,it is concluded that the reasonable value of buffer time.By setting reasonable buffer time can get effective utilization of the train running,reduce the delayed train.
