客运专线车站接发车进路选择优化

为了给客运专线车站接发的列车合理安排接发车进路,构建了进路选择多目标优化模型。优化目标为列车选择进路的偏好最大、到发线均衡使用,约束条件主要有到发线作业间隔时间约束、进路冲突约束。基于目标协调优化思想,提出了该多目标优化模型的求解方法。以济南西站为例,运用本文方法对15:00:00~21:00:00时段的到发线运用、进路选择方案进行求解。结果表明:方案较好地达到了两目标,较为合理。可见,模型能够更准确地描述列车占用各到发线、进路的不同,适用于求解客运专线运行图编制阶段的进路选择问题。

Optimized Selection of Receiving and Dispatching Routes of Passenger Dedicated Lines

In this paper,for the purpose of more reasonable arrangement of the receiving and dispatching routes of the passenger dedicated stations,we established a multi-objective optimization model,proposed the solution method based on the thinking of objective coordination and optimization,and then in the case of Ji’nan West Station,used the method studied previously to obtain the solution for the selection of receiving and dispatching routes between 15:00:00 and 21:00:00,finding that the solution could satisfy the two objectives very well.
