摘要
针对直觉模糊粗糙集的相似度量问题,提出了一种基于海明距离的直觉模糊粗糙集相似度量方法。首先给出了两个直觉模糊粗糙值间的相似度量方法,并揭示了它的若干重要性质。然后,在此基础上,又提出了一种基于海明距离的直觉模糊粗糙集相似度量方法,并证明它也具有同样的性质。最后用数值算例验证了这种方法的有效性。
A similarity measure method based on the Hamming distance is proposed to solve the problem of the similarity measures of intuition fuzzy rough sets. Firstly, a similarity measure method for measuring the degree of similarity between two intuition fuzzy rough elements is given, and some of its important characters were revealed. Secondly, based on it, a similarity measure method of intuition fuzzy rough sets based on the Hamming distance is proposed, and has proved this method to have same characters. Finally, the method is verified its validity by a numerical computation example.
