도시철도 시스템 유지보수를 위한 저장품의 적정 예비율 산정에 관한 연구

Urban rail are transporting passengers safely by general industrial purpose equipment and special equipment combination used only in urban rail with vehicles, signals, rail, electricity, etc. in case of equipment failure or performance fails, such equipments must be secured checked or replaced immediately to maintain the performance To do this, a constant quantity of each piece of equipment parts should be obtained as a spare part. to maintain the performance of urban rail systems, proper reserve rate calculation and timely purchase of the critical components is needed In this paper, propose that reserve rate calculation base on major storage products in order to optimal reserve rate calculation required for stable operation of urban railway system through the study for the impact on the train operation conditions and major system operating, the passenger services and the parts characteristics.
