Defining Spatial Information Requirements for Asymmetric Threat Behaviour in Simulation.

摘要

Across NATO, preparing the warfighter to face an asymmetric threat is a significant challenge. Insurgents evolve new tactics, techniques and procedures faster than coalition forces can respond. The current ability of simulation-based training systems to realistically model insurgent threat scenarios is limited by our ability to model relevant human behaviour. Standardization of data, concepts and models is a key enabler to allow human behaviour modelling activities to contribute to a growing, reusable capability, rather than requiring the development of single-point and inflexible solutions. Defining a simulation framework that supports execution of human derived content in simulated environments involves explicit definition of the inputs (observations, knowledge) and outputs (actions) of the human model, which defines the requirements that the cognitive model imposes on a synthetic environment. This paper presents an analysis of insurgent decision making, focused on deriving the information requirements for a robust model of Improvised Explosive Device (IED) emplacement. These information requirements are grouped into three classes of information. First, spatial information requirements are compared to the information normally found in the synthetic natural environment representation (i.e., terrain database) of a military simulation. Second, the impact of context specific information requirements is outlined. Finally, the requirement for domain knowledge is discussed. Future activities of the project will focus on the use of human factors tools and methods, including Cognitive Task Analysis (CTA) and ontologies to directly configure the execution of human behaviour models.
