Abstract: Based on the concept of hesitant fuzzy entropy, this paper introduces the concepts of entropy and similarity measures for interval-valued hesitant fuzzy information, and discusses their relationships. Firstly, the axiomatic definition of entropy for interval-valued hesitant fuzzy sets is proposed. Two entropy measure formulas are further developed, and they satisfies four axiomatic requirements of interval-valued hesitant fuzzy entropy. Then, the paper presents the concept of the interval-valued hesitant fuzzy weighted entropy depending on the interval-valued hesitant fuzzy entropy. Finally, the concept of interval-valued hesitant fuzzy similarity measures is given, and it studies the relationships between interval-valued hesitant fuzzy similarity measures and interval-valued hesitant fuzzy entropy.

Key words: Interval-Valued Hesitant Fuzzy Sets(IVHFS), entropy, similarity measures

摘要: 基于犹豫模糊熵的概念,提出了区间犹豫模糊熵和相似度的概念,同时研究了它们之间的相互关系。给出了区间犹豫模糊熵的公理化定义,在此基础上构造了两种形式的熵测度公式,并且证明了它们满足区间犹豫模糊熵的四条公理化准则;依据区间犹豫模糊熵引入了区间犹豫模糊加权熵的概念;提出了区间犹豫模糊相似度的概念,并且研究了区间犹豫模糊环境下的熵和相似度之间的关系。
