ToolKit BDD Engine

The Binary Decision Diagram analysis technique (BDD) available in ITEM ToolKit, offers an exciting leap forward in fault and event tree analysis. These new capabilities are included alongside the existing Fault Tree Module and offer the following benefits:

Calculates EXACT probabilities for undesired events, as opposed to conventional approximate methods such as Esary-Proschan
Compare approximation results with BDD's exact results quickly
Phenomenally fast analysis times (350,000 cut sets per second)
Can be used alongside the existing fault tree analysis techniques
Numerous distributions available to model event failure probabilities
Exact computation of event importance parameters
Time dependant analysis
Models incoherent fault trees
