Fault Diagnosis Based on Combination of Fault Tree and Rough Set Theory
Jinshan Li · Journal of Hunan Institute of Engineering · 2009
How to get knowledge about system's faults and construct the structure of fault tree automatically are key problems.By applying rough set theory to fault diagnosis of fault tree,looking for logical relationship of the various fault source signal and constucting fault-tree model,acquiring and streamlining the fault knowledge is extracted from samples by rough set.The fault study analysis showed that the combination of fault tree and rough set theory for fault diagnosis can effectively compress fault feature space and achieve fast and accurate fault reasoning.
