Mygal' G. Working out the identification method of operator's fatigue state of "man-machine-environment" system

The subject of the research - an operator of the "man-machine-environment" system. The objec-tive of the research - development of the opera-tor's fatigue state identification method for estimating and forecasting the "man-machine-environment" system reliability. The methods of the research - informational processes thermodynamics, reflex electrodiagnostics, psycho-physiological methods. Instrumentation - control and measurement instrumentation, AD converter and PC. Theoretical and practical results - the technique for selecting, structuring and processing data on the operator's functional state and proprietary/innovative devices for its realization were designed; for parameters which integrally show the operator's functional state the new regularities of their systemic changing were determined; the new criteria, graphic symbols, charts, phase-plane portrait which define the fatigue state were introduced; the concept of the functionally integrated approach to determination of the operator's functional state was evolved; the evolutionary entropy model was built and the functional states of possible classes were simulated as well as the character-istic indications of the state graphic symbol were validated; the integral-differential method of the operator's fatigue state identification was developed that enables to estimate and prognosticate reliability of the operator's organism. The research results extend ergonomic support of the "man-machine-environment" systems and promote optimization of the operator's work. Application extent - the method, the technique and the devices are applied in production (firm "Delta", Lvov) and university educational process (State Airspace University, University of Internal Affairs, Kharkov). The field of application - transport enterprises, energy industries, educational institutions.
