AN OPTIMIZED ALGORITHM FOR CALCULATING TOPEVENT FAILURE PROBABILITY OF FAULT TREE BASED ON THE BINARY DECISION DIAGRAMS TECHNIQUE

摘要

Fault tree analysis technique is often used to calculate the topevent failure probability of the numeration system. The traditional fault tree analysis is often up against the bottleneck of accuracy and efficiency when dealing with large fault tree structures. The Binary Decision Diagram (BDD) is highly efficient and precise in calculating the top event probability by computer This paper aims to provide an algorithm of fault tree by using an optimized calculation or analysis method of the BDD technique.
