Expert advisory system determining the functional reliability of the human operator based on psychological and psychophysiological indicators

Abstract

The article is dedicated to the formation of a "generalized portrait" of the condition of the human operator, which is the main component of the ergatic system, based on psychophysiological indicators, and on this basis, providing corrective advice through an expert-advisory system. A formal-constructive model "generalized portrait" is created according to the stratified description of psychological and psychophysiological indicators. Each indicator included in the strats is realized by means of the corresponding software. Each component of the "generalized portrait" is assigned to different scale types (ratio, interval, ordinal, nominative). The theory of fuzzy sets and relations is used to unify different types of scales. The decision and advice functional block of the expert-advisory system makes a decision about the functional reliability based on the fuzzy knowledge based on the current state of the human-operator.
