| Abstract: | The paper studies the probability characteristic of the reparable time for a system suffering delayed random damage. That is, the safe time period of the system in its initial operation is a random variable, then it suffers random impact arriving by the rule of Poisson process and comes into damage. The article deduces the density function and characteristic function of the reparable time and the reparable probability of the system by mathematical means of the conditional stochastic process and conditional Markov process. |

| Keywords: | System analysis distribution and characteristic conditional Markov process partial differential equation. |
