Abstract
Asymmetric/urban warfare, improvised explosive devices (IEDs), and dirty bombs are dominating over conventional warfare, and there is an urgent need to deal with them systematically. Effective strategies of thwarting terrorism continue to be the top priority for international communities. This paper presents a research approach for Situation Awareness and Threat/Impact Assessment strategies for a genre of UW problems. The approach is based on a formal domain ontology and a scenario authoring and simulation environment A class of hybrid deductive (model-based) and inductive reasoning approaches are applied to the scenario simulation and performance evaluation studies are conducted. Such an approach can be used for training purposes as well as fusion technology development. An example will be presented.
