도시철도 차량의 지식기반 유지보수 방안

Since the most part of maintenance work for EMU depends on the worker's know-how, the quality of maintenance is different according to the worker's skill and experience. Especially EMU is composed of the various parts such as electrics, electronics, communication, signal, and machinery, etc., and performs its function by their organic work. Therefore it is very difficult to improve the quality of maintenance for EMU. In this paper we purpose how to change the know-how-based maintenance method to knowledge-based maintenance method. Consequently we can ensure the quality of maintenance for EMU, and improve the quality by continuous maintaining the knowledge.
