Abstract

Decision rules of fault diagnosis were acquired after analyzing the inconsistent fault information system. By converting inconsistent information system into a consistent one based on the application of generalized decision function of inconsistent information system of rough sets and then by reducing the condition attributes of fault diagnosis based on the compatible relation of rough sets, relative reduction of inconsistent information system was acquired and decision rules were found. When it came to fault system of diesel, the inconsistent fault system of it can be converted into a consistent one and the decision rules acquisition of fault diagnosis proved to be effective.
