单向S-区间值模糊粗糙集及应用
One-direction S-interval-valued fuzzy rough set and its application
摘要
Abstract
This paper introduces the concept of dynamic interval-valued fuzzy approximation in interval-valued fuzzy rough set based on the theory of Z.Pawlak rough set. Based on this, the concept of one-direction S-interval-valued fuzzy rough set is proposed, and its general structure and basic properties are given. The concepts of rough equivalent, cut set and roughness of one-direction S-interval-valued fuzzy rough set are defined, and related properties are discussed and proved. Then, the application and existing value of one-direction S-interval-valued fuzzy rough set is given.关键词
