Iran's economy has been facing the problem of inflation for more than half a century. According to empirical studies, various visible and invisible political, economic, cultural, etc. factors have been effective in increasing the inflation rate; Factors that sometimes cannot all be considered in one economic model. Therefore, it is not possible to comment with certainty on the extent to which some factors affect the inflation rate with conventional methods. Based on this argument, in order to use an appropriate method in this study, from the fuzzy approach to investigate the severity of the impact of economic sanctions imposed on Iran along with other variables affecting inflation, in the period after the Islamic Revolution (1978-2020), Used. The results show that severe economic sanctions against Iran with a strong fuzzy coefficient, have a positive and significant effect on inflation in Iran. Also, liquidity, people's adaptive expectations, budget deficit and exchange rate fluctuations, respectively, after the severe sanctions, have had the greatest impact on increasing inflation. The obtained fuzzy coefficients of oil revenues and economic growth (excluding oil) indicate the negative effect of these two variables on the inflation rate in Iran.
