Currently, great importance is given to the use of mathematical modeling in the conduct of system analysis. The article reveals the definitions of system analysis and mathematical modeling. Problems that can be solved with the help of system analysis are described, and the main tasks of system analysis are formulated. It is noted that system analysis is used mainly for research and design of large and complex systems. The methodological bases for the development of a mathematical model are analyzed.
