摘要:

直觉模糊集IFS是模糊集的进一步推广,比传统的模糊集在处理模糊性和不确定性等方面更具灵活性和实用性。已有的部分相似度测量方法,不满足相似度的公理化或有些存在反直觉的情形。通过对Boran和AKay提出的直觉模糊集的相似性度量的研究,提出了一种新的改进的相似度测量公式,证明了该公式的合理性,最后通过实例说明了该方法的有效性。

Abstract:

Intuitionistic Fuzzy Sets (IFS) are the further promotion of fuzzy sets,which are more flexible and practical than the traditional Fuzzy sets in dealing with vagueness and uncertainty.However,existing similarity measurement methods cannot realize the axiomatization of the similarity,or they may incur some counterintuitive instances.Based on the similarity measurement of intuitionistic fuzzy sets proposed by Boran and Akay,we propose a novel measurement formula.Example analysis demonstrates the rationality and effectiveness of the proposed formula.
