고속철도차량 추진제어장치의 수명주기비용 평가 모델에 관한 연구

This paper presents about the evaluation model for life cycle cost of motor block in the KTX. Until now, most life cycle cost of the system as a whole that has been studied. but in case of railway industry part, LCC studies are needed on the subsystem like a propulsion control system becouse subsystems are developed continuously localization. Therefore, In this paper presents cost breakdown structure for life cycle cost (LCC) estimation for localization development of propulsion control system (Motor Block) in high speed railway vehicle (KTX). Also to design CBS, it was analyzed physical breakdown structure (PBS) on propulsion control system in view of maintenance cost. Based on this, we describe evaluation model as possible for life cycle cost.
