摘要: 为了揭示Vague集和经典集之间的联系,在Vague集二元截集的基础上,提出了两个新的Vague集的分解定理。Vague集的分解定理表明Vague集可以由它分解出的截集簇来表示,而这些截集簇都是普通集。最后实例说明了其有效性。

关键词: Vague集, 二元截集, 分解定理

Abstract: To reveal the relationships between Vague sets and classical sets,two new decomposition theorems of Vague sets based on the binary cut sets are proposed.The decomposision theorems show that every Vague set can be expressed by the family of cut sets decomposed by itself,and the elements in the family of cut sets are classical sets.Finally,some examples are given to illustrate their effectiveness.

Key words: Vague sets, binary cut sets, decomposition theorem
