关于Vague集之间的相似度量

On Measures of Similarity between Vague Sets

首先提出了定义一个Vague集之间的相似度量所应该满足的若干准则,而后指出了Chen给出的vague集之间的相似度量所存在的缺陷,并分析了李凡提出的vague集之间的相似度量,在此基础上,基于对不确定性信息处理的背景,提出了一种新的相似度量方法。研究了这一新的相似度量的性质。

This paper firstly suggests some rules which is considered when y ou give a similarity measure for measuring the degree of similarity between elemen ts and between vague sets.After that,the paper shows by examples the deficien-cy of Chen's similarity measures between vague sets and proposes a new similar ity measures for measuring the degree of similarity between vague sets.The prop osed measures can provide a useful way for measuring the similarity between vag ue sets.
