摘要
Abstract
An extended rough set model based on similarity of variable precision dynamic tolerance relation is proposed on the basis of comparing the existing extended rough set models. This model divides the tolerance classes according to the similarity of two objects and missing property value. The realistic feasibility and effectiveness of the model to handle the incomplete information systems is confirmed through the comparison among the expanded rough set models of tolerance relation, similarity relation,limited tolerance relation. At the end, the concept of relative positive region and attribute reduction rule are given.关键词
