{Sigma}{Pi}-Patrec is a computer program for the evaluation of exact top-event probability of fault trees. Exact value of top-events are necessary for real applications with large basic events probabilities (i.e.: P {ge} 0.1). {Sigma}{Pi}-Patrec allows the user to evaluate the exact value which would otherwise lead to erroneous, overly conservative results. {Sigma}{Pi}-Patrec requires an IBM compatible PC with an 80386 or newer processor, VGA graphics capability, and a mouse.
