Analysis of Large Fault Trees based on Simplified BDD Algorithm
Wei Liu · International Journal of Performability Engineering · 2017
A simplified BDD analysis method (SimBDD) is proposed to solve the problem of temporal and spatial explosion and low computational efficiency of getting the fault tree's minimum cut sets in BDD method.On the basis of using SimBDD to get the minimum cutting sets, the failure paths of the fault tree are obtained by the hierarchical processing method.Tests are taken on large fault trees with this method.The results demonstrate that the method is efficient.
