Fuzzy MCDM Techniques for Analysing the Risk Factors of COVID-19 and FLU

Decision-making is inevitable in day-to-day life. Fuzzy multi-criteria decision-making is incorporated for better decision-making in almost all kinds of complex problems. In this research notable advantages of VIKOR and TOPSIS techniques employed with fuzzy triangular numbers to analyse the risk factors of COVID-19 and FLU. The comparative analysis is illustrated to find the most influencing risk factors of COVID-19 and FLU by comparing each and every situation of patients. At last, the resistance test was also included to check the final rankings and outcome.
