Rail Inspection Cost Prediction Model Considering the Degradation of a Rail

초록

Railway inspection procedures have been traditionally planned based on the knowledge and experience of each company. The risk of rail failure increases with tonnage which is defined as the amount of traffic passing the rail. Generally, it is beneficial to renew rails before the risks and cost becomes very high. In this paper, a rail inspection cost model considering the reliability of NDE technique which is represented by PoD curve and the rail degradation process is presented and rail inspection cost is calculated varying PoD curve and rail inspection interval
