摘　　要：合理的摘挂列车开行方案能够有效提高区段内车流组织水平和设备使用效率。摘挂列车开行方案除受区间通过能力、车站设备能力、车流量分布等因素的影响外,还与是否开行区段列车有关。根据区段列车和摘挂列车的运行特点,通过分析区段与摘挂列车运行过程中的车小时消耗以及对区间通过能力的影响,建立以区段列车和摘挂列车的集结车小时和运行车小时、摘挂列车在站停留车小时和停站次数最小化为目标函数的优化模型。最后结合数值算例,利用优化软件对模型进行求解,得出总车小时消耗最少的车流组织方案,验证了模型的可行性。An optimal operation scheme of pick-up and drop train can effectively improve the level of car flow organization and utilization efficiency of equipment in the district.The operation scheme of pick-up and drop train is influenced by some factors such as the carrying capacity of the block section,the capacity of the station equipment,the distribution of the car flow,and so on.And it is also related to whether to operate the district train.According to the running characteristics of district train and pick-up and drop train,this paper analyzed the car-hour consumption and the influence of carrying capacity of the block section during trains running on the district,set up the optimization model by taking the minimization of accumulation car-hour and running car-hour of district train and pick-up and drop train,stopping car-hour and stop number of pick-up and drop train as the objective function.Finally,a numerical example was presented and the model was solved by using optimization software.The car flow organization scheme was acquired with the least total car-hour consumption,which proved the feasibility of the model.
