Technique of Monitoring a Human Operator’s Behavior in Man-Machine Systems

Abstract

Monitoring a human operator’s behavior in man-machine systems is aimed at detecting and diagnosing unwanted behavioral deviations of a human operator from the preset sequence of actions, taking into account their possible response to the current state of the system. The human operator’s behavior is described using the nondeterministic finite-state machine (FSM) model. Techniques for constructing and determinizating this model are proposed to ensure the minimal possible loss of information. The solution of the task is illustrated by the example of working IT system operators.
