| Abstract: | There are incompleterness and uncertained infromation in fault diagnosis of military aircraft,which increase the difficulty of real-time diagnosis.Rough sets theory has much more superiority of processing uncomplete and uncorrect information.The paper introduces the knowledge expression system and discernibility matrix,and then analies the two attributive reduction algorithms of decisiontable based on discernibility matrix.The results show that the two algorithms can reduce the data and the fault diagnosis ... |
