Research on Evaluation Model of Situational Awareness for The Grid Information Network

The components of situational awareness for the grid information network are analyzed, and models for evaluating the ability of situational awareness are established both in the information domain and the cognitive domain. In the information domain, three aspects of information quantity including completeness, accuracy and timeliness are proposed to evaluate the situational awareness ability. In the cognitive domain, the Logistic equation is established in combination with the quantitative analyses of the information domain in order to describe the change of the situational awareness from time to time. Keywords-the grid information network; situational awareness; completeness; accuracy; timeliness; Logistic.
