Abstract

Aim. The paper aims to develop an algorithm that would allow finding the required number of items (SPTA) for a complex system, whose elements may or may not be maintainable.

Methods. Markov models were used for describing the system. The final probabilities were obtained using the Kolmogorov equation. The Kolmogorov system of equations has a stationary solution. Classical methods of the probability theory and mathematical dependability theory were used.

Conclusions. The paper formalizes the problem of determining the required number of SPTAs for a system with elements that have a probability of being repaired. A Markov graph is constructed. Using induction, a stationary solution was found for the Kolmogorov system of equations. An example of finding the required number of SPTAs is given.
