In this paper, the problem of ensuring the competitiveness of a high-tech enterprise of the aircraft industry by optimal management of its information and other basic resources in conditions of increased economic security requirements is investigated. Modern approaches to the creation of an effective management system for high-tech enterprises of the aircraft industry based on the results of the analysis of its economic and mathematical model are analyzed. As a result of the conducted research, the task of creating a special information subsystem for managing information and other basic resources of a high-tech enterprise in the aircraft industry (using the example of material, technical and information components) was formulated and solved in order to modernize the management activities of such an enterprise as a component of the overall system for ensuring its competitiveness in foreign and domestic markets in conditions of increased economic security requirements.
