A Situation and Threat Assessment Model Based on Group Analysis

The understanding of how commanders make their decisions is the precondition for the study of decision aiding. But this is not the case in current STA researches. In previous studies, researchers just organize relevant STA functions according to cognitive level, but pay little attention to the real decision making procedure. To solve this problem, the concept of group analysis and a functional model of it are proposed in this paper with a view not to the cognitive level but to the procedure of military decision making. Then a STA model based on group analysis is established. This model forms the awareness of the whole situation part by part and level by level which is in accord with commanders’ cognition procedure. Thus it not only makes the decision aiding more efficiently but also makes the design of military decision support system more conveniently.
