In particular, chewing gum stuck on the Mass Rapid Transit train doors stopped the trains from moving. 特别是当口香糖被吐在大型的高速铁路列车的门档上,会阻止列车前进。
In order to solve an MRT ( mass rapid transportation ) train operation simulation model and obtain the optimum operation curve, an improved multi-objective GA ( genetic algorithm ) was proposed. 为了求解城市快速交通(MRT)列车运行模拟模型,寻找最优的列车运行控制曲线,构造了多目标改进遗传算法。
