本文将区间值直觉模糊有序加权余弦相似度测度与广义有序加权平均算子相结合,提出了区间值直觉模糊有序加权余弦相似度测度。IVIFOWCS测度的主要优点是提供了一个参数化的相似性测度族,决策者可以使用IVIFOWCS测度考虑多种可能性,并根据自己的兴趣选择聚合算子。研究了区间值直觉模糊有序加权算法余弦相似度(IVIFOWACS)测度和区间值直觉模糊最大余弦相似度(IVIFMAXCS)测度。IVIFOWCS测度不仅是某种相似性测度的推广,而且可以处理区间值直觉模糊值的不同决策矩阵之间的相关性。在此基础上,提出了IVIFOWCS测度在群体决策问题中的应用。最后通过实例将现有的相似性度量与IVIFOWCS度量进行了比较。
We present the interval-valued intuitionistic fuzzy ordered weighted cosine similarity (IVIFOWCS) measure in this paper, which combines the interval-valued intuitionistic fuzzy cosine similarity measure with the generalized ordered weighted averaging operator. The main advantage of the IVIFOWCS measure provides a parameterized family of similarity measures, and the decision maker can use the IVIFOWCS measure to consider a lot of possibilities and select the aggregation operator in accordance with his interests. We have studied some of its main properties and particular cases such as the interval-valued intuitionistic fuzzy ordered weighted arithmetic cosine similarity (IVIFOWACS) measure and the interval-valued intuitionistic fuzzy maximum cosine similarity (IVIFMAXCS) measure. The IVIFOWCS measure not only is a generalization of some similarity measure, but also it can deal with the correlation of different decision matrices for interval-valued intuitionistic fuzzy values. Furthermore, we present an application of IVIFOWCS measure to the group decision-making problem. Finally the existing similarity measures are compared with the IVIFOWCS measure by an illustrative example.
