Abstract :
The paper deals with redundant systems consisting of i.i.d. units with repair. There are 2 kinds of spare units 1) warm standby units with instant perfect replacement and 2) cold stock units which can be supplied after a delay only. The replacement mechanism and the derivation of the mean ´time to first system failure´ (TFSF) using Markov renewal processes are illustrated on two models. The influence of stock unit replacement time on the mean TFSF is studied.
