| Abstract(in English) | The minimal cut-AND structure can be expressed with an AND conjunction of an output and all inputs that compose a minimal cut set in Fault Tree Analysis (FTA). For the structure, the failed state of the output becomes true when all failed states of inputs exist simultaneously. In practices, there are cases where the output of the minimal cut-AND structure depends not only on all failed states of inputs but also on the sequence of occurrences of those failures. This paper assists in quantifying this kind failure logic using Markov model. Algorithms to estimate the probability that the output is in a failed state at time t and the statistically expected number of failures of the output per unit time at time t are proposed for the basic events characterized of exponential distributions with common failure and repair rates. |
