A Study on Necessity to Introduce Prognostic Maintenance of Rolling Stock

Abstract

The easiest way to prevent the railway vehicle failure is to heavily invest money and labor into maintenance and advance the vehicle replacement and maintenance cycles. However, the actual operational maintenance resources (cost and time) are limited, making it difficult to predict when and where sudden failures would occur. Therefore, many studies have examined how to build an effective maintenance system that can minimize failures based on limited resource availability. In this paper, I will examine the necessity of predictive maintenance and research trends.
