Abstract

The functional stability of an object is its property to be preserved during a given time of execution of its main functions within the limits set by regulatory requirements, under conditions of influence of flows of failures, malfunctions, failures. As you know, the structure of the automated enterprise management system is dynamically changing in the process of identifying and restoring the fact of the failure of the functioning of subsystems. In this case, the functioning of the system is not violated, and it constantly performs its basic functions, possibly with a decrease in quality by reducing the degree of redundancy in the restructuring. For end users, bounce events and the recovery process remain transparent and invisible. Intelligent systems that have in their composition computing systems are characterized by the influence of their flow of failures. In addition, the intensity of the flow of failures and unstable failures is not less than the intensity of constant failures. Therefore, the question of using the hierarchical structure regarding the means of ensuring the functional stability of the automated enterprise management system is relevant today. The paper proposes using a hierarchical approach for organizing the means of ensuring functional stability. The scientific novelty consists in using the function of interaction between the levels of the automated enterprise management system hierarchy, where the role of arguments uses the values of other functions provided to this level by the lower levels or implemented in it itself. It is shown that such organization of means of providing functional stability allows: to reduce the time of system response to emerging failures; to make changes in the means of providing functional stability in the process of accumulation of knowledge about failures.

Keywords: functional stability, automated enterprise management system, external and internal destabilizing factors.
