Abstract

In this paper we study the effect of failure detection equipment(FDE)s on system availability. A new repair scheme is considered for the step of repairing FDE which becomes out of order in the course of repairing the main system(MS). We compute and compare the availability of MS.

이 논문에서는 고장감지장치(FDE)가 시스템 가용도에 미치는 영향을 연구한다. 주시스템(MS) 수리 도중에 고장이 발생한 FDE를 수리하기 위한 새로운 수리 정책을 고려한다. 이 논문의 주요 목적은 MS의 가용도를 계산하고 비교하는 데에 있다.
