Computing system failure probabilities a comparison of SIGMA PI with other methods.

Computing system failure probabilities [electronic resource] : a comparison of SIGMA PI with other methods.

SIGMA PI is the fastest method available today of accurately calculating probabilities associated with large fault trees. To demonstrate this, we describe the major problems that have prevented successful evaluation of these probabilities by other methods in the past. Then, we describe how SIGMA PI...

Description
Summary:SIGMA PI is the fastest method available today of accurately calculating probabilities associated with large fault trees. To demonstrate this, we describe the major problems that have prevented successful evaluation of these probabilities by other methods in the past. Then, we describe how SIGMA PI addresses all of these problems, and we compare the performance of SIGMA PI with that of leading alternative methods under selected problem scenarios. 13 refs., 3 figs., 2 tabs.
