Abstract: Knowledge discovery on oil fault diagnosis system (OFDS) is essentially a problem of pattern classifier and recognition. Based on Rough set theory and tribology system, knowledge discovery model of OFDS is proposed. By applying the concept of inclusion degree to Rough set theory, method of knowledge reduction and discovery based on inclusion degree is deduced, and the relation between the inclusion degree and measures of rough set data analysis is also discussed. In the end an application example of diesel engine OFDS with 9 attributes is given to show the effect of this method.

Key words: Fault diagnosis, Inclusion degree, Knowledge discovery, Oil analysis, Rough set
