摘要:

为提高铁路客运站作业调度水平,降低列车延误影响,采用数字孪生技术构建铁路客运站技术作业模型,通过实时数据采集,基于随机森林的作业时间预测,作业模拟以及智能决策,提出基于数字孪生的铁路客运站技术作业实时调度方法。将此调度方法应用于某实际铁路客运站中,实验结果表明:该方法能对实际作业进行高精度预测及模拟;使用三种数字孪生决策规则能有效降低列车作业延误。研究论证了该数字孪生模型能应用于实际车站管理,提高作业实时调度水平。

Abstract:

To improve the operation scheduling of railway passenger stations and reduce the train delays, digital twin technology is used to establish a railway passenger station operation model. Through real-time data acquisition, based on the operation time prediction of random forest method, operation simulation and decision-making, a real-time scheduling method of railway passenger station operations based on digital twin is proposed, and applied in a real railway passenger station. The experimental results show that the method can effectively forecast and simulate the actual operation. Three kinds of digital twin scheduling rules have been used, which can reduce the delay time of train operations. It is proved that the digital twin model can improve the real-time scheduling of operations in the daily management of stations.

Key words: railway transport, real-time scheduling, digital twin, operations, operations delay
