Semi-Markov Models

Let us determine operating time to failure $T_{+}$ and average stationary restoration time $T_{-}$ of the system S.

$\underset{E_{+}}{\int }\rho (de)P(e,E_{-})=\underset{0}{\overset{\tau }{\int }}G(s)\rho (0s)ds+\rho (1\tau )\overline{G}(\tau )=$

In such a way, on the basis of (1.17), (1.18) we have:

$T_{+}=\tau +E\alpha H(\tau ),T_{-}=E\beta H(\tau )-\tau .$

Based on the results obtained let us determine the value of time reserve ensuring necessary system reliability.
