This paper explores normalization methods for intuitionistic fuzzy matrices, enhancing consistency in decision analysis and multi-criteria decision-making.
The concept of intuitionistic fuzzy sets (IFS) provides a comprehensive framework for dealing with uncertainty, incorporating both membership and non-membership functions. Normalization of intuitionistic fuzzy matrices is an essential process in decision-making and data analysis where the matrix entries are expressed in terms of intuitionistic fuzzy numbers (IFNs). This paper explores the methods and techniques for normalizing intuitionistic fuzzy matrices to ensure that the degree of membership and non-membership values are consistent, thus enhancing the reliability of the matrix in decision analysis problems. We propose an efficient approach to normalize intuitionistic fuzzy matrices, ensuring the transformed values retain their essential characteristics while adhering to the constraints of the fuzzy set theory. The study also addresses the application of normalized intuitionistic fuzzy matrices in multi-criteria decision-making (MCDM) and other relevant areas such as image processing, pattern recognition, and system modelling. Several illustrative examples are provided to demonstrate the effectiveness of the proposed normalization techniques
