ÕªÒª
Rough Sets Theory and Grey System Theory both have the same advantage of processing inaccuracy data, so a fusion algorithm based on Rough Sets Theory and GM (1, 1) Grey prediction model is proposed. The attribute reduction algorithm of Rough Sets Theory reduces the fault diagnosis decision table, and the optimal diagnosis rules are deduced. Then, GM (1, 1) calculates the condition attributes predicted value of reduced decision table by their test value, which substitutes back to the reduction diagnosis decision table for fault prediction. It is verified in one fault of some aero radio equipment, and the results indicate that the efficiency and accuracy of fault prediction are both quite higher, which provides the foundation to improve the equipment reliability and maintainability.
