| Abstract: | According to the practical conditions of aeroengine fault diagnosis,the paper firstly analyzed limitation of rough sets,then processed the samples set from experts experience by introducing variable precision rough sets model.And the samples sets of history faults were analyzed by the received decision-rules.The rate of identification was high.The result proves the effect of this method and the applicability of the decision-rules received from the small samples set. |
