λ-相似关系下的区间粗糙数粗糙集模型
Interval Rough Number Rough Set Model Under λ-Similarity Relation
摘要
Abstract
Aiming at the limitation of classical rough set theory in dealing with interval rough number information system, an interval similarity rate is defined. Combining the interval similarity rate and introducing two parameters α and β , the concept of interval rough number similarity is proposed. The concepts of λ-similarity relation and similarity class are given by introducing the parameter λ and combining the concept of interval rough similarity. The interval rough set model under λ-similarity relation is proposed. The relevant properties of the rough set model are studied and explained by an example.关键词
