A Study on the RCM and expert system of Urban railway system for Maintenance Computerization

도시철도유지보수체계 시스템의 RCM과 전문가시스템에 관한 연구

The maintenance CALS system for car of urban transit is a part of standardization and development of urban transit system, and We have been performed the establishment of maintenance CALS system from 2001 to 2005. The RAMS for management computerization system are utilized in a variety of CALS system for user's convenience and safety in maintenance. Ever since its inception though, the urban transit has searched for ways to improve reliability, availability, maintainability and safety of the railway subsystem. In this paper, This system include RAMS(reliability, availability, maintainability and safety) and expert system of the vehicles shall be enhanced in the future.
