Beta BFR (Binomial Failure Rate) Model
Input Parameters: ρ, QSH, QLS
Unavailability of CCF events:
Where:
= The independent failure probability of each component.
= The conditional probability of failure of each component (given a non-lethal shock).
= The occurrence probability of non-lethal shock.
= The occurrence probability of lethal shock.Therefore, the total failure probability of an event is Qt = Q1 + ρ * QSH + QLS. In this case, irrespective of the value of n, all the parameters are required.
For n = 4:
Input Parameters: ρ, QSH, QLS
Unavailability of CCF events:
