가능한 시스템의 신뢰성 분석에 중요한 문제 중의 하나는 유 지보수 효과를 모델링하는 것인데 불완전 유지보수는 Kijima[3] 가 제안한 2가지 실질 노후상태(Virtual Age) 모형으로 설명 할 수 있다. Abstract An important problem in reliability analysis for repairable systems is to model the maintenance effect. The most of researches have assumed two extreme cases; one is perfect maintenance and the other is minimal maintenance. However, many of maintenances performed by domestic subway operators are imperfect maintenances which have the effect between both of two extreme

This paper deals with a case study on determining imperfect maintenance interval by using the level of maintenance effect through reliability analysis of PDS.
