Abstract: Consider a k‐out‐of‐n system with independent repairable components. Assume that the repair and failure distributions are exponential with parameters {μ1, ⃛,μn} and {λ1, ⃛,λn}, respectively. In this article we show that if λi – μi = Δ for all i then the life distribution of the system is increasing failure rate (IFR).
