针对列车运行图冗余时间布局影响列车运行图弹性的问题,对运行图冗余时间分配方法进行研究.首先,通过分析列车实际运行数据,总结列车运行晚点分布规律,基于对运行图关键位置及关键列车的判断,在运行图冗余时间总量不变的前提下,对列车运行图冗余时间进行重新分配.然后,在满足列车作业间隔约束条件的前提下,对列车到发时刻进行冲突疏解,形成新的列车运行图.最后,选取京沪高速铁路某日列车运行图进行算例分析,通过高速铁路列车运行自动调整系统,比较在不同初始扰动方案下运行图冗余时间分配前后的弹性效果.调整结果表明:冗余时间重新分配前列车运行平均总晚点时间为143 min,冗余时间重新分配后列车运行平均总晚点时间缩小为123 min,降低了13.99％,证明该冗余时间分配方法可有效降低外界扰动下的运行图总晚点时间,提升运行图弹性.
Improving timetable resilience for high-speed railways through time supplement allocation
This study investigates methods to enhance the resilience of train timetables by optimizing the time supplement allocation. Firstly, an analysis of actual train operation data is conducted to iden-tify patterns in train delays. Based on critical positions and key train assessments within the timetable, a redistribution of time supplements is proposed while maintaining the overall quantity unchanged. Sub-sequently, conflicts in train schedules are resolved under operational interval constraints to formulate a revised train timetable. Finally, a case study using a daily timetable of the Beijing-Shanghai high-speed railway evaluates the effectiveness of the proposed method under varying initial disturbance sce-narios using an automatic train operation adjustment system. Results demonstrate that the average to-tal delay decreases from 143 minutes before reallocating time supplements to 123 minutes thereafter, indicating a 13.99％ reduction. This approach effectively mitigates external disruptions to improve timetable resilience.
