| 摘 要： | 对粗糙集、Vague集及粗糙Vague集的概念、知识表示方法进行了讨论，描述了粗糙Vague集的相关概念，在研究了粗糙Vague集相似性度量方法的基础上，提出了一种对踌躇度пv（x）k步细化的k步相似度量新方法，并且研究了该方法的相关性质。进一步对k步相似度量在k趋向无穷时求极限，得出粗糙Vague集退化为模糊集的特例情况。

| Abstract: | In this paper,some concepts of rough sets,vague sets and rough Vague sets are discussed,and the method of knowl-edge expression is approached.The concept of rough vague-valued and similarity measures for measuring the degree of similarity between elements(rough vague-valued:RV-valued) are studied,and then a new method of similarity measures for k steps between rough Vague sets(valued) is given,its some properties are studied.Similarity measures for k steps are limited while k tends to in-finity,then rough V... |
