ABSTRACT
Psychophysiological peculiarities of the effect of 24-hour shift work on psychophysiological indices of an operator's efficiency have been considered. It is found that significant manifestations of the fatigue have been developed in servicemen-operators as a result of daily shift-work. The informative psychophysiological characteristics, which can be used as reliable indicators of fatigue level, have been distinguished. A hypothesis has been proposed on the availability of several compensatory mechanisms in maintenance of the work capacity in operators in long-term shift work. An integral index of the reliability of operators' activity has been developed, allowing to assess the quality of work, using a wide range of intensities of the proposed signals as well as to receive data on the overall possibilities of an operator to process information at the given level of reliability.

The authors considered contemporary state of occupational psychophysiologic selection in Ukraine, stressed problems of using efficiency parameters as external criteria of occupational selection, suggested methodic approach to considering structure of relationships between psychophysiologic functions in designing key rules of occupational psychophysiologic selection. The authors specified structural and functional scheme of organizing governmental system for occupational psychophysiologic selection.

The evoked dynamics of the omega potential and its relation to some parameters of mental working capacity in operators working at steam power plants were studied under production conditions. The dependence of the omegagram type on the background level of the omega potential was determined. 12 types of omegagrams constituting two A and B clusters with negative correlation were distinguished. The highest level of mental working capacity was observed in operators with the background values of the omega potential not exceeding 45 mV and with the omegagram type belonging to the B cluster.
