Human Modeling in Nuclear Engineering

Abstract

Review on progress of research and development on human modeling methods is made from the viewpoint of its importance on total man-machine system reliabilitys urrounding nuclear power plant operation. Basic notions on three differenta pproaches of human modeling (behavioristics,c ognitives and sociologistics)a re firstlyi ntroduced, followed by the explanation of fundamental scheme to understand human cognitives at man-machine interface and the mechanisms of human error and its classification. Then, general methodologies on human cognitive model by AI are explained with the brief summary of various R & D activitiesn ow prevailing in the human modeling communities around the world. A new method of dealing with group human reliabilitiys also introduced which is based on sociologisticm athematical model. Lastly, problems on human model validation are discussed, followed by the introduction of new experimental method to estimate human cognitive state by psycho-physiological measurement, which is a new methodology plausible for human model validation. © 1994, Atomic Energy Society of Japan.
