Abstract

Abstract: In this paper,some concepts of rough sets and vague sets are discussed,and the method of knowledge expression is approached.A new concept of rough vague sets（RV sets） is proposed,the concept of rough vague-valued and similarity measures for measuring the degree of similarity between elements（rough vague-valued：RV-valued） are given,and then its some properties are studied.

Key words: rough sets, vague sets, rough vague sets, rough vague valued, similarity measure

摘要： 对粗糙集和Vague集的概念、知识表示方法进行了讨论,把粗糙集和Vague集进行了融合,描述了粗糙Vague集概念,给出粗糙Vague值的相关概念及其相似性度量的一种新方法,研究了粗糙Vague集的相关性质及其相似性度量的方法。

关键词: 粗糙集, Vague集, 粗糙Vague集, 粗糙Vague值, 相似性度量
