Abstract

In this article, we develop a novel TOPSIS approach for solving the multi-attribute decision-making (MADM) problems under the q-rung orthopair fuzzy numbers (q-RONs) environment. For this, we have proposed a new entropy measure (EM) for q-rung orthopair fuzzy set (q-ROFS) to measure the fuzziness of the q-ROFS. Numerous features of the proposed EM of q-ROFS are also illustrated. Afterwards, by utilizing the proposed EM, a TOPSIS approach has been developed for tackling MADM issues under the q-ROFNs context. To exemplify the proposed TOPSIS technique, a real-life MADM example has been studied. Comparative studies are also developed to illustrate the TOPSIS approach’s efficiency.
