The Influence of Ergonomics of Human-Machine Systems on the Emergence and Development of Cognitive Function Disorders

摘要

The aim of the work is to obtain mathematical models for predicting and early diagnosis of cognitive disorders of operators of human-machine systems, provoked by prolonged psycho-emotional stress and chronic fatigue arising from ergonomic risk factors. The work uses technical means of monitoring the state of various components of such cognitive functions as attention, memory, thinking and energy characteristics of biologically active points "associated" with the studied cognitive functions. As a basic mathematical apparatus, the synthesis methodology of hybrid fuzzy decision rules is used. In the course of the research, mathematical models were obtained for predicting and early diagnosis of impaired attention and memory functions associated with the professional activities of operators of human-machine systems. During mathematical modeling, expert assessment and statistical tests, it was found that the confidence in the correct decision-making using the obtained mathematical models exceeds 0.85.
