Condition Management of High-speed Railway Infrastructure Based on Full Life Cycle

A large number of historical data shows, equipment condition of high-speed railway showing a bathtub curve shape. Data on equipment state stored in different management departments, and the infrastructure management of railway design, construction stage and operation stage are disjointed. The above problems make the exploration of the equipment lifetime distribution difficulty, make equipment repair cycle is difficult to forecast. This paper presents the whole life cycle of equipment management based on the theory of high speed railway and present a personalized modeling for high speed railway equipment condition deterioration, and application in the high-speed rail grid management information system.
