距离测度是集合理论中的一个重要基础概念.自直觉模糊集提出以来,直觉模糊距离受到了广泛的关注,近年来已有多种形式的距离测度被提出.大多数现存直觉模糊距离存在反例,且没有考虑直觉模糊集三个参数的性质.引入了模糊距离的概念,综合体现了经典距离和犹豫指数的特点.提出了一种新的直觉模糊距离测度,并给出了相应的证明.基于单元素直觉模糊集,构建了一个人工基准的测试集来比较本文提出的距离测度和广泛使用的距离测度.结果表明,提出的距离测度没有任何反例,并且能够很好地反映出犹豫度的波动性.“,”Distance measure is a basic and crucial notion of set theory.Since the intuitionistic fuzzy sets (IFSs) were put forward,distance between IFSs has been widely concerned by some researchers and many types of measures have been proposed.Most of them have counter-intuitive cases and ignore the characteristics of three parameter properties of IFSs.The concept of fuzzy distance was introduced,which embodied the characteristics of classical distance and highlights the characteristics of hesitance index simultaneously.A new fuzzy distance measure was proposed,and the corresponding proof was included.An artificial benchmark test set of distance measure was constructed based on single-element IFSs,which was applied to compare the proposed distance measure with the widely used distance measures.Results show that the proposed distance does not provide any counter-intuitive cases and the waver that brought from hesitancy degree can be well reflected.
