Similarity measures on cubic intuitionistic fuzzy sets

The primary objective of this study is to develop a similarity measure on cubic intuitionistic fuzzy sets. First, we have proposed a series of similarity measures on cubic intuitionistic fuzzy sets based on the geometric model, set-theoretic approach, and matching function. Additionally, examples are provided to demonstrate the effectiveness and importance of the proposed similarity measures. These examples address the decision-making problems based on the technique for order preference by similarity to an ideal solution (TOPSIS) method.
