ABSTRACT
Nowadays manual work has to a greater or lesser extent been replaced by mental work. In this respect, it is critical not only to design operators’ work, but also to reorganize the particular operator’s working process itself. This reorganization is based on comparing the general professional requirements with an operator’s individual characteristics (physical, psychological, psychophysiological, social), as well as his or her capacity for adaptation. Adaptation of individual characteristics and general requirements affects the dynamics of an operator’s work functional structure during his or her lifetime. An ergonomic approach to improving human interaction with the work tools, as well as with the environment, is to provide mutual adaptation of a human working functional structure and the work environment. The mechanisms of this adaptation may differ depending on the conditions, location, and time of operators’ work, i.e. they depend not only on the interaction human-machine environment, but also on dynamics of this interaction throughout the whole work cycle.
