摘要 本文研究了一般关系下 Vague 集合的近似问题,建立了一般关系下粗糙 Vague 近似的框架。在分析经典的粗集理论、模糊集理论、Vague 集理论三者关系的基础上,提出了一般关系下粗糙 Vague 集的概念,并定义了粗糙Vague 近似算子,讨论了粗糙 Vague 的性质。本文的结果对进一步开展粗糙集 Vague 集的研究具有一定的意义。 in this paper, the upper and low rough approximation operators based on general binary relation of Vague set are studied. Firstly, the relationship between Rough sets,Fuzzy sets and Vague sets is analysized, which are all impor tant tools for AI and KDD. Some results for the rough Vague sets are presented, which are some meaningful to farther study of the rough Vague sets.
