熵和相似度是模糊集理论中2个很重要的信息度量工具.给出了直觉模糊集的直觉熵与直觉相似度的定义,并给出直觉熵公式,讨论了直觉熵与直觉相似度的关系.
直觉模糊集;熵;相似度
熵是模糊理论中的重要概念,用来描述模糊集的模糊性程度.Zadeh[1]于1965年首次提出模糊熵的概念.1986年,Atanassov[2]对Zadeh提出的模糊集[3]进行了推广,提出了直觉模糊集,包含隶属度、非隶属度和犹豫度3个参数,可以更加灵活地描述一些不确定信息.Szmidt[4]等在模糊集熵定义的基础上,利用对直觉模糊集的几何解释给出了熵定义及熵公式.随后,学者们从不同的角度对熵进行研究,提出了不同形式的熵公式[5-8],并将其应用于多属性决策和模式识别等领域.在模糊集理论中,用来刻画不同模糊集相似性程度的重要工具是相似度.随着直觉模糊集的发展,关于直觉模糊集的相似度及应用方面的研究也越来越多[9-13].文献[14]提出了模糊集的直觉熵与直觉相似度的定义,本文给出了直觉模糊集的直觉熵与直觉相似度的定义,并讨论直觉熵与直觉相似度的关系.
另一方面
基于模糊集理论中对熵和相似度的研究,本文给出了直觉模糊集的直觉熵和直觉相似度的定义及公式,并讨论了它们之间的关系,进一步可将直觉熵用于解决模糊多属性决策问题,说明其合理性.
