Binary Decision Diagram
Fault
Tree Analysis using Binary Decision Diagram - ITEM ToolKit
|
...BDD Analysis Software... |
- Calculates EXACT probabilities for undesired events, as opposed to conventional approximate methods such as Esary Proschan.
- Compare approximation results with BDD's exact results by flick of a switch.
- Phenomenally fast analysis times (350,000 cut sets per second).
- The BDD techniques 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.
History
In 1990, a number of companies (CEA, Dassault Aviation, EDF, ELF-EP, Renault, Schneider Electric, SGN, Technicatome) and laboratories (LaBRI, LADS) formed a group to explore the use of binary decision diagrams in the field of Operating Dependability and Safety. After a few years working on the subject, one of the results produced by the group was a software tool dedicated to processing probabilistic formulae. Since then, the application has continuously evolved to cater for the varied demands in qualitative and quantitative calculus of the members of the group.
In recent years Binary Decision Diagram's advancement has suffered from its lack of a sophisticated, graphical interface for the fault tree diagram construction. Therefore, Item Software's highly advanced fault tree construction facilities have now been combined with the BDD analysis engine to form a complete, state of the art analysis tool, offering some of the most powerful and flexible safety analysis tools available anywhere today.
