摘要/Abstract

摘要： 以Z.Pawlak粗集理论为基础，将动态模糊近似概念引入Dubois模糊粗糙集中。提出了双向S-模糊粗糙集概念，给出了双向S-模糊粗糙集的结构与性质。分析了双向S-模糊粗糙集与Z.Pawlak粗集、Dubois模糊粗集、S-粗集、S-粗糙模糊集及单向S-模糊粗糙集之间的关系。给出了双向S-模糊粗糙集的应用及存在价值。

Abstract: The paper introduces the concept of dynamic fuzzy approximation in Dubois fuzzy rough set based on the theory of Z.Pawlak rough set. Based on this, the concept of two-direction S-rough set is proposed, and its general structure and basic properties are given. The relationship between a two-direction S-fuzzy rough set and Z.Pawlak rough set, Dubois fuzzy rough set, S-rough set and S-rough fuzzy set, between a two-direction S-fuzzy rough set and a one-direction S-fuzzy rough set are analyzed. The application and existing value of two-direction S-fuzzy rough set is given.

Key words: dynamic fuzzy set, fuzzy elementary transfers, Dubois fuzzy rough set, two-direction S-fuzzy rough
