Abstract


A computerized model of human cognitive behavior in monitoring and diagnosing plant transient has been developed as a part of integrated simulation system of human-machine-interaction (HCI) in nuclear power plant. The employed general framework of human modeling is first described, followed by the description of detailed modeling of both the monitoring and diagnosing phases. For the usability validation of the developed human modeling, computer simulation experiments have been conducted to deduce human cognitive reliability curves, by connecting the computerized model of human cognitive information processing with the dynamic simulator of nuclear power plant through man-machine interface simulator. The results of computer simulation were well agreed with those of laboratory experiments.
