基于突发情况下的高速铁路票额调整与停站方案协同优化

Collaborative Optimization of High-Speed Railway Ticket Allocation Adjustment and Station Stop Plan under Emergency Conditions

  • 摘要: 在面对突发情况时,高速铁路列车因为不可控因素会出现车次取消的情况,导致大量的旅客滞留在车站,不仅会出现客流流失,还可能会导致安全事故。从铁路效益和列车停站时间两个方面出发,优先考虑长途旅客的需求,以票额分配和停站方案作为决策变量,以客票收益最大、增加停站的成本以及停站时间最小为目标,建立票额分配与停站方案的协同优化模型。以京沪高铁部分区段为例,在列车停运的情况下,利用后续列车的剩余运能对滞留旅客进行疏散,并使用COPT求解器对京沪高铁实例进行求解,结果表明增加停站的方式对滞留旅客疏散效果良好,客运收益损失降低98.7%,疏散率最高达到90.37%,并避免了一定的经济损失,将突发情况带来的负面影响降到了可控范围内。

     

    Abstract: When facing emergency situations, the high-speed railway trains may have trips cancelled due to uncontrollable factors, resulting in a large number of passengers being stranded at the stations. Not only will there be a loss of passenger flow, but also may result in safety accidents. Commences with two aspects, namely railway benefits and the train stop time at stations. It gives priority to the needs of long-distance passengers, takes the ticket allocation and the station stopping plan as decision variables, aims at maximizing the passenger ticket revenue, minimizing the cost of adding stops and the stop time, and establishes a collaborative optimization model for ticket allocation and station stopping plan. Taking a section of the Beijing-Shanghai High-Speed Railway as an example, in the case of train suspension, the remaining transport capacity of subsequent trains is used to evacuate the stranded passengers. The COPT solver is used to solve the example of the Beijing-Shanghai High-Speed Railway. The results show that the method of adding station stops has a good effect on the evacuation of stranded passengers, the loss of passenger transport revenue has been reduced by 98.7%, with the highest evacuation rate reaching 90.37%. It also avoids certain economic losses and reduces the negative impact brought by emergency situations to a controllable range.
