“…Senders' original scanning model was subsequently elaborated by others (Carbonell, 1966;Carbonell et al, 1968;Smallwood, 1967;Baron and Kleinman, 1969;Baron et al, 1970;Kleinman et al, 1970;Kleinman and Curry, 1977;Levison, 1971;Wewerinke, 1981; Stein Table 1 Dynamics of FISA-2 simulator. and Wewerinke, 1983;Sheridan, 1970;Kvalseth, 1975Kvalseth, , 1977aMoray, 1980Moray, , 1981Moray, , 1986Moray et al, 1983;Crossman et al, 1974;Senders, 1983;Miao et al, 1997;Kim and Seong, 2006a,b;Wickens et al, 2001) to account for value in addition to the bandwidth (event rate). The bandwidth obviously plays an important role in the monitoring behavior in NPPs.…”

“…Operator may want to know further into the SGTR such as the location of rupture, the leakage amount (or diameter of leakage breach), and so on, which can be assessed by analyzing bandwidths (event rates) of a set of process parameters (symptoms) representing changing value. The expectancy played the most significant role in the models for situation assessment based on Bayesian inference (Miao et al, 1997;Kim and Seong, 2006a,b). The two models were based on dynamics rules of a NPP.…”

“…Attention has been paid to the information searching behavior of operators during abnormal states such as accident, incident, or transient conditions (Miao et al, 1997;Kim and Seong, 2006a,b). Informational importance of an information source should be a function of its ability to discriminate among competing hypotheses (abnormal states) of the cause of a plant symptom.…”

“…The two models were based on dynamics rules of a NPP. Usually there is a set of symptoms given an abnormal state of a NPP (i.e., situation-events relations) (Miao et al, 1997). Symptoms generally have diagnostic attributes.…”

“…One approach is to apply the Bayesian Belief Networks (BBNs) to predict operators' SA in Endsley's (1995) Level-2: Comprehension (e.g., Kim and Seong 2006;Miao et al 1997). The other analytical model is Attention-Situation Awareness (A-SA) (Wickens et al 2005).…”

Abstract. Human factors engineering is important and has been brought into the regulations for the operation of nuclear power plants. However, there is still a discrepancy between the regulations and the practices. In this study, the SEEV model was used as a framework to construct an analytical model for predicting situation awareness in terms of the gaze distribution percentage on alarm displays in nuclear power plants. Two similar multiple linear regression models were constructed and validated based on the data of eye-tracking from 40 participants. Results showed that these two models were consistent with the SEEV framework. The values of R-square for these two models were 0.78 and 0.83, whereas the values of predicted R-square were 0.77 and 0.72. The analytical model developed in this study should be a necessary complement to current practice of situation awareness measurement. In addition, through the model, the improvement of alarm display design can be achieved in a resourceeffective manner.

Building and maintaining the information superiority is the basis of the principle of active defense, integrated guarding in the cyberspace. In this paper, a novel method based on grey verhulst model was introduced to forecast the network system's security situation. Starting with unequal interval original risk data series, the proposed method choosed grey verhulst model or its inverse function to forecast the future risk value of network system, ant then it could modify the forecasting precision based on multilevel residual error. Simulation results reveal that the presented model not only gains the intuitionistic curve graph of network security situation, but also can achieve satisfactory precision. At the same time, it is simple in use and deserves further study to fully explore its potential for evaluation issues.
