RCM system modeling in developing an advanced urban EMU

Recent reliability centered maintenance (RCM) process has been increasingly applied for modern rolling stock applications to ensure the optimum maintenance of trains in its operating context. While significant benefits and tools at the appropriate stage in a new project can be achieved by applying the RCM methods, the general modeling and design framework for the RCM system implementation have to be application-specific, i.e., RCM procedures and analysis models have to be adaptive due to the upgrades/changes with complicated, modular, and smart devices equipped in the new system. Therefore, this paper investigates critical considerations in modeling and developing a new RCM system which should be implemented to the advanced urban EMU in Korea. Recommended RCM system design strategies will benefit the development of relevant large scale systems.
