"ELRAFT" A Computer Program for the Efficient Logic Reduction Analysis of Fault Trees

One of the most powerful and widely used techniques in the field of reliability analysis is the Fault Tree. In Fault Tree analysis, component failures or conditions (basic events) are graphically depicted in the necessary combinations to cause subsystem or system failures (secondary events). Application of probability theory to the logic scheme thus depicted permits computation of system failure probability where the probabilities of the basic events are known.
