Article 12 pp,Polish Naval University
The semi-Markov reliability model of the cold standby system with renewal is
presented in the paper. The model is some modification of the model that was considered by
Barlow & Proshan (1965), Brodi & Pogosian (1978). To describe the reliability evolution of the
system, we construct a semi-Markov process by defining the states and the renewal kernel of
that one. In our model the time to failure of the system is represented by a random variable
that denotes the first passage time from the given state to the subset of states. Appropriate
theorems from the semi-Markov processes theory allow us to calculate the reliability function
and mean time to failure. As calculating an exact reliability function of the system by using
Laplace transform is often complicated we apply a theorem which deals with perturbed semi-
Markov processes to obtain an approximate reliability function of the system.
