Semi-Markov Model of a Technical System with Maintenance and Time Reserve

Ensuring high reliability of technical systems requires the construction of adequate mathematical models of their functioning, taking into account not only individual factors that increase reliability (maintenance, redundancy, control, etc.), but also their combinations. In this paper, a semi-Markov model of a technical system with calendar maintenance and time reserve is constructed. For an approximate determination of the stationary characteristics of the reliability of the system, the phase merging scheme algorithm is used. The effect of the time reserve on the reliability characteristics of the system under consideration is analyzed.
