摘要
区别度是刻画模糊集之间差异程度的一种度量方式,区别度研究具有重要理论意义.本文给出了粗糙模糊集区别度度量应满足的若干条件,提出了三种形式的粗糙模糊集区别度,并讨论了它们的基本性质.
The difference degree is a measure of the extent of the way which describes the differences of rough fuzzy, so the study of difference has an important theoretic significance. In this paper, the number of conditions that the difference degree of rough fuzzy sets should have must be satisfied. Three forms of the differences of rough fuzzy sets are given and their basic properties are discussed.
