Dependability of a Complex System

Abstract

In this paper the behaviour of a complex system consisting of n components of constant failure rates λ 1 , λ 2 , …, λ n and repair rates pit μ 1 , μ 2 , …, μ n is examined. The probability that the system is operating at time t is obtained. Also the probability that it is in outage stage i at time t has been determined. At the end, a particular case where μ ı 's are equal is considered.
