城市轨道交通列车交路编组一体化编制方法

本文对影响列车交路方案和编组方案编制的各要素进行定量分析,从乘客和运营方两个角度建立列车交路编组一体化编组模型,并设计了相应的遗传求解算法。将求解得到的方案与单一交路、单一编组方案进行比较,结果显示,利用本文方案通过灵活编组、开行小交路等方式,可以减少13.6%的候车时间、2.65%的运营成本、12.88%的运用车数量。通过灵敏度分析,证明了该方案的可行性。

Integrated planning method of routing and formation for urban rail transit

In this paper, quantitative analysis of all the factors affecting train routing scheme and train formation plan was made, and the integrated planning model was established from two perspectives of passengers and operators, and related solving algorithm was put forward based on genetic algorithm. When compared with the scheme of single route and single formation, the results showed that using the optimization scheme presented in this paper by flexible formation and short routing operation could reduce 13.6% waiting time, 2.65% operating cost and 12.88% the number of serviceable car, and its feasibility was proved by sensitivity analysis.
