Mathematical Modelling Economy

open access: yesBulletin of the South Ural State University. Series "Mathematical Modelling, Programming and Computer Software", 2023
Summary: The article presents an overview of the main methods of economic modelling used in scientific research over the past twenty years. This overview does not claim to cover all areas, methods and models used in scientific research in the field of economics, since it is impossible to do within a single article. We consider mathematical modelling of
