Abstract

Abstract: The notion that a vague relation R is α-decomposable is introduced.Two necessary and sufficient conditions that a vague relation R is α-decomposable are given.As R is α-decomposable，the solution sets of A and B with R=AαB are given，respectively.

Key words: vague relation, α-decomposition, solution set

摘要： 提出了Vague关系R是可α-分解的概念。得到Vague关系R是可α-分解的两个等价刻画。在Vague关系R是可α-分解时，分别给出了使R=AαB成立的A与B的解集。

关键词: Vague关系, α-分解, 解集
