Interaction of a human operator with an automated control system.

Abstract

The technology of interaction between computers (computer systems) and humans is an important scientific problem. Scientifically based technologies of the interaction of two information systems – human and computer – are the ones that will allow optimizing human activity. Nowadays, it is becoming more and more obvious that the most promising way to improve the quality of information processes in human activity, including in automated management systems, is the joint use of human capabilities and technical means as information systems. As a result, the task of studying the main aspects of human-machine interaction becomes topical. The main feature of human-machine interaction is a combination of formalized information processes and structures and informal (as a rule, creative) processing of information. The latter helps both find ways to solve complex problems that are not contained in formal models (algorithms) and to organize the solution process as a holistic system. Human-machine interaction cannot be fully algorithmized (in the formal sense), but it is possible to develop technology for the joint activity of humans and technical systems when solving problems. The article examines some indicators of human operator behavior in interaction with an automated control system, mathematical models of a human operator, and the issue of optimization of human actions. The described interaction of the human operator with an automated control system (ACS) shows the important role of the «human factor», which must be fully taken into account when designing an ACS, as an obligatory component of the ACS control complex. It is shown that as the level of automation increases, the role of a human in technical systems to ensure their smooth operation increases. Some criteria for the characteristics of the «human factor» and ergonomic equipment of the operator's workplace have been formulated.
