Study on solving method for structural importance of fault tree
Tianwen Jiang · Journal of Safety Science and Technology · 2012
When conducting safety system analysis by fault tree analysis,the structural importance of fault tree has usually been solved by minimum cut set or minimum path set.Due to the different results by minimum cut set and minimum path set analysis,the structural importance of fault tree will be differenced.Which lends to the divergence in system analysis results.The methods of calculating structural importance by solving structural importance coefficient and solving probability importance were put forward.The practical example proved that the solved results of structural importance was consistent with the results by minimum path set analysis,and the results were accurate.
