Abstract
The optimization measures in the physical protection system monitoring center of a nuclear power plant include the prioritization of alarm signals, optimization of sound and light alarm form, improvement of the layout of video monitor screen, security training, and strengthening of organizational management. Based on the fuzzy analytic hierarchy process, the influence of these factors on the probability of alert assessment and guard’s respond time in the EASI method are quantitatively analyzed. Making full use of the measures for prioritization of alarm signals can effectively promote the improvement of human-computer interaction efficiency. The degree of influence of the four factors (guarder’s status, decision strategy, guarder’s training and organization management) on guard’s decision-making is roughly the same.
Kurzfassung
Zu den Optimierungsmaßnahmen in der Überwachungszentrale des Sicherungssystems eines Kernkraftwerks gehören die Priorisierung von Alarmsignalen, die Optimierung der Ton- und Lichtalarmformen, die Verbesserung des Layouts des Videomonitorbildschirms, Sicherheitstraining und die Stärkung des Organisationsmanagements. Basierend auf dem Verfahren der unscharfen analytischen Hierarchie wird der Einfluss dieser Faktoren auf die Wahrscheinlichkeit der Alarmbewertung und die Reaktionszeit des Wachpersonals in der EASI-Methode quantitativ analysiert. Die volle Ausschöpfung der Maßnahmen zur Priorisierung von Alarmsignalen kann die Verbesserung der Effizienz der Mensch-Computer-Interaktion wirksam fördern. Der Grad des Einflusses der vier Faktoren (Status des Wächters, Entscheidungsstrategie, Ausbildung des Wächters und Organisationsmanagement) auf die Entscheidungsfindung des Wächters ist ungefähr gleich.
