摘要
目前铁路设备种类多、数量广、价值高,能够监测设备运行状态,及时发现并处理故障设备,是提高铁路信息化管理的重要手段。由于铁路设备故障重要程度不同,针对设备故障处理优先级排序问题,提出了一种基于SVM模型的设备故障优先级评价方法。针对铁路设备故障特性,建立了铁路设备故障评价指标体系。仿真结果证明SVM模型具有良好的拟合效果,能够为铁路设备故障处理优先级提供有效决策依据。
With the characteristic of wide variety,large number and high value,railway equipment need to be monitored to discover the fault problem and be maintained timely,which is the important method to improve the management of railway informatization.Because of the different importance of railway equipment fault problem,the evaluation method of railway equipment failure priority based on SVM model is proposed.For the railway equipment failure characteristics,the evaluation index system of railway equipment failure is established.The simulation results show that the SVM model has good fitting effect,which can provide effective decision-making basis for the priority for railway equipment failure.
