Dependability of a Complex System

In this paper the behaviour of a complex system consisting of n components of constant failure rates λ₁, λ₂, …, λ_n and repair rates pit μ₁, μ₂, …, 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.
