摘要
分析当前旅客列车车底的运用方式,提出铁路实行车底套用可以提高车底运用效率,并且可以减少车底接续时间。通过构建车次连接网络图,对初始可行车次连接任务串进行搜索,以每个车次都能被覆盖且仅被覆盖一次为约束条件,以车底使用数量最少为目标函数,建立不固定区段的车底套用模型,并采用遗传算法进行求解。结合北京、武汉、广州、上海4个地区一些大型客运站旅客列车的运行情况对模型加以运用,结果表明:车底的实际接续时间减少,减少了车底的使用数量。
Through the analysis of application of the current passenger train set,this article puts forward that the application of the train set assignment can increase its efficiency and decrease the connecting time of the train set assignment at the station. The paper searches for the initially feasible train number connection duty strings by constructing train number connection network diagram, establishes the model of the train set assignment in uncertain sections, in which each train number is covered and only once as the constraint condition, and the minimum number of the train set assignment in use is the objective function, and finally adopts the genetic algorithm to solve the problem. The model is used to verify the operation conditions of passenger trains at some large passenger stations of four areas such as Beijing, Wuhan, Guangzhou and Shanghai. The results show that the connecting time of the train set assignment decreases and the train set assignment is less used in quantities
