Fuzzy sets are finding their application in situations where are available the estimates given by experts, different indicators as well as uncertainty of information. If in the case of ordinary sets an element can belong to a certain set or not, then in the fuzzy sets element may also have some degree of belonging.

Various activities have been undertaken in connection with the application of fuzzy sets in the economy, in particular: investment projects evaluation, bank insolvency risk assessment, stock portfolio optimization, business macroeconomic environment and marketing analysis.

It was noted that further studies will be directed to the application of mathematical apparatus for solving the problems of constitutionality monitoring.
