On the basis of the observation of practical defects in ceramic tiles and the limitations of the conventional model of rough sets, this paper proposed a new method of defect analysis for ceramic tiles by introducing a variable precision rough set model which uses approximation dependency of variable rough sets to realize attribute reduction and to establish decision making rules.
