在原始Vague集基础上提出动态的Vague集,即S-Vague集,由此提出了S-粗Vague集概念。接着给出了S-粗Vague集结构与性质,分析了S-粗Vague集与Z.Pawlak粗集、Dubois粗糙模糊集以及S-粗集之间的关系,给出了S-粗Vague集的应用。
Based on primitive Vague set,a dynamic Vague set is presented namely S-Vague set.Based on this,S-rough Vague set is proposed and its general structure and properties are given.The relationships between S-rough Vague sets and Z.Pawlak rough sets between S-rough Vague sets and Dubois rough fuzzy sets between S-rough Vague set and S-rough set are analyzed. The application of the S-rough Vague set is given.
