Prime Implicants of Noncoherent Fault Trees

Computer-assisted fault-tree construction using a knowledge-based approach

“…In fault trees without replicated events, the cut sets are minimal. For noncoherent fault trees, the minimal cut sets are replaced by a set of prime implicants in Boolean algebra [46,78].…”

“…The elemental probability of at least one event in 10,000 yr (1.6 x is combined in 54 Chapter 7 with elemental probabilities of other significant events to form the probabilities of the eight summary sce-55 narios considered in the present study. (Worrell and Stack, 1978). No background on fault-tree formalism and notation is given in Appendix B.…”
