根据区段管内列车的运行过程和车流产生情况,分析列车的各种车小时消耗,在着重考虑集结完成的车流在站等待挂车车小时消耗的前提下,推导出相应的计算公式。建立以总车小时消耗最少为目标的优化模型,并利用分层求解算法对模型进行求解,进而求得总车小时消耗最少的运输组织方案。 According to the running process of the train and the traffic flow in the section tube, the paper analyzes the train hourly consumption, and deduces the corresponding calculation formula under the premise of focusing on the hourly waiting time of the trolley waiting at the station. The optimization model with the least total hourly consumption of vehicles is established, and the model is solved by using the hierarchical algorithm. Then the transportation organization scheme with the least hourly total vehicle consumption is obtained.
