Abstract : A type-2 fuzzy system is used to assess pandemic severity of places. To assess the situation, test positivity, vaccination status, total numbers of infected cases, active cases, recovered cases, deceased cases, population density, etc., are considered. Available imprecise data are converted into type-2 fuzzy numbers and type-2 fuzzy inference system is used. A case study on the recent COVID-19 pandemic situation is performed. The achieved results and comparison reflect usefulness and superiority of the model.
