Evaluation of Best Mobile Phone in India using Entropy based TOPSIS, EDAS and CODAS as MCDM methods

Pradeep Kumar Deka

Abstract


Manufacturers frequently release new mobile phone models with improved features and technical characteristics to keep up with consumers’ changing preferences. This illustrates a classic instance of multi-criteria decision making (MCDM) considering the difficulty of selecting a product with numerous selection criteria and numerous possibilities. To assist customers in making decisions, the major goal of this study is to rank the mobile phone among several viable possibilities. Ten alternate models (under Rs.30, 000 category) from various manufacturers have been chosen based on a website (Gadgets360.com) listing in July 2023 under the heading, ‘Best mobile phones under 30000 in India’. Seven prominent characteristics that serve as distinguishing criteria are picked for ranking purposes. To eliminate any subjective ideas, the weights to these criteria are calculated using the Entropy approach to be applied to MCDM algorithms, namely TOPSIS, EDAS and CODAS to rank these mobile phones. The ranking was effectively attained, and the Spearman Correlation analysis revealed a strong positive correlation between the procedures and the outcomes.

Keywords: MCDM, Mobile Phone Ranking, TOPSIS, EDAS, CODAS
