Application of Reliability Centered Maintenance for Waterworks after Constructing CMMS (Computerized Maintenance Management System)

유지관리업무 시스템(CMMS) 구축에 따른 수력발전 및 수도설비를 위한 신뢰도 기반 유지보수(RCM) 적용

This paper presents application of RCM(Reliability Centered Maintenance) in waterworks system. The reliability-based probability model for predicting the failure probability is established and FTA(Fault Tree Analysis) is proposed to considering RCM. To calculate failure probability, Weibull distribution is usually used due to age related reliability. FTA is an engineering analysis which is using logic symbols. The real historical data of CMMS(Computerized Maintenance Management System) make full use of case study for waterworks system. Consequently, the RCM would be likely to permit utilities to reduce overall costs in maintenance and improve the total benefit.
