ABSTRACT
Decision making in many domains is complicated and difficult, inspiring the development of decision aids intended to improve performance. Antiair warfare (AAW) is one such area. The decision space is complex, in that the number of variables is large and the interrelationships among them often convoluted. Absolute categorical analysis is often difficult, if not impossible, due to the absence of complete knowledge regarding the situation. Missing, imperfect, or ambiguous data, as well as incomplete knowledge of relevant prior probabilities makes it a near certainty that complete analysis of any given situation is impossible. Decision making in the absence of absolute knowledge, together with the complexity of the situations, often requires some form of approximate reasoning.
