Basic event ordering in fault tree analyses using binary decision diagram
XI Shuren · Journal of Tsinghua University(Science and Technology) · 2005
Fault Tree Analysis(FTA) is widely used to analyze system reliability.This paper describes the use of the Binary Decision Diagram(BDD) for FTA and the ordering of the basic events.The Fault Tree is first transformed to a BDD,and then cut sets are directly obtained.The ordering of the basic events is crucial to the size of the resulting BDD and the analysis speed,so the optimal ordering is a key part of the analysis.Ordering rules presented applicable for most FTA cases can reduce the number of BDD nodes by almost half.
