Towards a Generic Behaviour Modelling Interface

NATO Task Group 128 identifies that behaviour in military simulations is often too mechanistic in nature. In this paper we will argue that behaviour in simulations can be improved if the two central aspects of behaviour modelling, i.e. action selection and performance modelling, are not addressed as separate issues, but as interacting instead. We will describe how the interaction between these aspects may be improved by the introduction of an interfacing layer, consisting of human capabilities. Although capability based modelling is not new, it is usually limited to cognition and information processing. It is our view that the use of capabilities in HBR should be expanded to include perception, motor skills and physiology. We will also describe the CHAOS behaviour model, that uses capabilities as a behaviour modelling interface. CHAOS can therefore be seen as an illustration and proof of concept of the ideas proposed in this paper. See also ADA564696.
