Abstract
<jats:p>The textbook presents the basic concepts and methodology of problem formulation in the framework of economic and mathematical modeling. The main aspects of the analysis of processes and phenomena using modern mathematical apparatus, as well as approaches to the construction and research of models focused on solving practical economic problems are considered. Attention is paid to the use of modeling methods to justify management decisions in conditions of uncertainty and risk. Examples and algorithms are proposed that make it possible to apply economic and mathematical modeling aimed at improving management efficiency and ensuring economic security. It is intended for students in the field of "Economic security", specializing in "Economic and legal support of economic security".</jats:p>
