Abstract:
The article characterizes the general working conditions of the man-operator (MO) in the complex human-machine systems (CHMS). Specific examples of CHMS are given. It is shown that work of MO demands the following terms: storing instructions for necessary actions in memory; perception and judgment of large volumes of information; operational recognition of dangerous situations; acceptance and timely implementation of management and technical decisions; estimates of their implementation effects. Features of CHMS real-time management are specified; original mathematical models for the MO solutions acceptance and implementation are offered. Variants of MO sensor systems for ensuring operator with necessary information are considered. The key psychophysiological parameters influencing the information perception and usage by MO are discussed: attention indicators, volumes of short-term and long-term memory, speeds of percepting different types of information, time expenditure on acceptance of one- and multicriteria solutions, durations of “motor reactions”; opportunities of side-by-side execution by MO of several works types, concerned with CHCM management. Variants of operator testing by specified parameters are analyzed. The expediency of accumulation and retrospective analysis of testing results for individual MOs or MO groups has been justified. The opportunities for MO training including use of the adaptive modes are described. The information models of MO activity in terms of CHMS and models of dynamic management of information volumes demonstrated to MO. Practical opportunities and restrictions on continuous monitoring and/or periodic control of MO in the course of work are analyzed. There are offered the mathematical models for optimizing volumes of control, considering positive and negative effects. Possible approaches to a posteriori estimates of the quality of MO activity are analyzed; particular and integral criteria for such estimates are considered. Possible methods for MO activity quality management are specified.
