The Fault Diagnosis of Vehicle Gear-Box Based on Gray-Rough Set Mode

To improve the precision of vehicle gear box fault diagnosis based on gray cognate method and reduce the inconsistency of decision, gray cognate analysis is combined with rough set theory to find the optimization eigenvector. It shows that the gray rough set mode can display the effect of each parameter and reduce the inconsistency of decision. Gray rough set theory can improve the precision and consistency of the methods of fault diagnosis based on rules.
