摘要
针对现有直觉模糊聚类方法中大多数未考虑指标权重,且计算结果为实数的问题,提出了一种基于新直觉模糊相似度的聚类方法。运用直觉模糊熵得到指标权重,构造了一种考虑指标权重的直觉模糊相似度公式,得到直觉模糊相似矩阵,构造了满意度阈值。决策者根据自身满意度偏好选择合适满意度阈值,将直觉模糊相似矩阵转化为实数矩阵,然后利用平方自合成方法得到模糊等价矩阵,选择适当的置信值进行聚类,最后通过实例验证所提方法的有效性和可行性。
Aiming at the problem, which most of the existing intuitionistic fuzzy clustering methods do not take the weight of the index into account and the calculation result is real number, a clustering method based on the new intuitionistic fuzzy similarity degree is pro- posed. By using the intuitionistic fuzzy entropy, the index weight is obtained, and an intuitionistic fuzzy similarity degree formula for attribute weight is constructed as well as an approach is developed to construct an intuitionistic fuzzy similarity matrix. A satisfaction threshold is designed and the decision maker selects the appropriate satisfaction threshold according to their own preference, and trans- forms the intuitionistic fuzzy similarity matrix into real matrix, then, the fuzzy equivalence matrix is obtained by using the square self synthesis method, selects the appropriate confidence value to cluster. Finally, an example shows the validity and feasibility of this method.
