Computer Simulation of Discrete Human-Machine Interaction for Providing Reliability and Cybersecurity of Critical Systems

The article considers the issues of preventing damage to complex critical systems, caused by cybersecurity unreliability and violations. The method of searching for ergonomic reserves is used. Within the framework of the human-system approach to the tasks of ensuring the reliability and cybersecurity of critical systems, the issues of human-machine interaction simulation by functional networks are considered. The activity of the human operator is proposed to be described in the terms of the functional-structural theory of the scientific school of professors A.I. Gubinsky and V.G. Evgrafov. The information technology was developed that ensures the implementation of procedures for describing, evaluating and variant simulation of human-machine interaction.
