Approaches to modelling economic system of the northern region

Abstract

The article presents the results of the review of the applied approaches to modelling regional branch systems. The article justifies the task of modelling the extractive industries as a basic branch of the economy of the northern regions of resource type. Technical prerequisites determine the need for the formation of new approaches to the methodology and algorithm for modelling complex systems. The author's conceptual map of the production subsystem is presented: mining in the relationship with the blocks (graphs) of the regional system. The requirements to the functionality of dynamic models and the choice of their factors for determining the stability of the components of the regional industry system are highlighted. The developed models will take into account system transformations from structural and technological shifts: cyclicality of industry crises, depletion of reserves, digital maturity, and ESG effects.
