Abstract

An exact and an approximate method for calculating the probability of occurrence of the output event from priority-AND (sequential) failure logic is given. The approximate method can be used during fault-tree analysis without modification to existing quantitative evaluation techniques. Assumptions made include s-independent, exponentially distributed, non-repairable basic events as input to the priority-AND failure logic.
