Classification and Experimental Study of Human Cognitive Reliability Model

By the simulator experiment for the Qinshan NPP operators, the identification method of parameters and classification of Human Cognitive Reliability model and the analysis method of the response time data are described. It is found that the main factor for classification is the normalized standard deviation, which is a critic parameter of Weibull distribution. Using the classification and analysis method presented in the paper, the cognitive reliability parameters for the Qinshan NPP operators are obtained from the Qinshan simulator experiment data. The result of the Qinshan experiment basically coincides with the IAEA experiment.
