摘要
作为铁路运输的关键组成部分,重载铁路对于我国货运的发展具有重大的影响,重载列车大都按计划运行,但是在实际运行过程中难免受到一些突发状况的影响。由于重载列车载重大,线路钢轨和车轮故障是日常突发事件,当突发事件发生时,其影响演化具有不确定性。突发事件的扰动时间是进行列车运行调整的重要参数,因此,需要对突发事件影响进行分析与演化推演。本文基于重载铁路列车突发事件处理的历史数据,构建数据驱动的重载铁路突发事件影响时长预测集成模型,进一步提高突发事件影响时长的预知能力。
As an important part of railway transportation,heavy-duty railways have a significant impact on the development of my country’s freight transport.Most heavy-duty trains operate as planned,but they are inevitably affected by unexpected situations during actual operation.The vehicle is very important,and the rail and wheel failures of the line are daily emergencies.When the emergencies occur,the impact of the emergencies is uncertain.However,the disturbance time of an emergency is an important parameter for the train dispatcher to adjust the train operation.Therefore,it is necessary to analyze and evolve the impact of the emergency,and build a data-driven based on the historical data of the emergency handling of heavy-load railway trains.The prediction model of the impact duration of heavy-haul railway emergencies improves the ability to predict the impact duration of emergencies.
