Abstract
Smart phone selection involves several product attributes and brand values of the manufacturing company, and the sets of alternatives, criteria, and decision-makers may be updated multiple times during the purchasing process. In this study, a multi-index multi-criteria decision-making approach is proposed using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) technique with intuitionistic fuzzy sets (IFS) measures based on score-based measures. The purchasing of electronic gadgets is considered, and a similarity-based solution to the multi-index, multi-criteria decision-making problem is proposed. The effectiveness of the suggested approach is demonstrated through a numerical scenario. The results highlight the efficacy of the proposed method in resolving specific decision-making problems in the marketplace.
