The past decade the Australian Defence Science and Technology Organisation (DSTO) have been actively pursuing the use of the Belief, Desires, and Intention (BDI) agent model in operations analysis and computer generated forces. It has been shown that the BDI approach to agent programming brings the particular advantage of using terms and concepts that are familiar to all. For instance, in Air Operations studies, the tactical behaviour of a simulated pilot can he reviewed and verified directly by a real pilot, through inspection of the simulated tactical reasoning processes. At present the challenge is to bring this a step forward with appropriate tools and a control environment that enable pilots to operate an uninhabited airbome vehicle (UAV) during mission by means of tactical directives. Our experience has demonstrated that the BDI model provides a suitable framework for capturing tactical behaviours in the air operation domain. We have also demonstrated that the representation of these behaviours in terms of BDI plans is6 readily understandable by domain experts. However the current development process requires an experienced BDI developer to work with a domain expert in order to develop an appropriate set of agent behaviours. We would like to remove the BDI developer fiom the loop ~ this paper represents a first step in the achievement of that objective. In order to remove the BDI developer, we need to answer the following questions: 1. Can we provide the domain expert with a suitable (nonprogramming) environment for specification of agent behaviours? Can agent behaviour in this domain he partitioned into a declarative component (involving goals and plans) and a domain specific kemel? The focus of this paper is the fKst question, and we describe recent work on such a specification environment. The idea is that for controlling a UAV as an 'autonomous wingman', the pilot instructs the UAV by forming and commanding tactical plans at a suitable level of abstraction. The autonomous wingman would process these plans in the 2.context of common-sense background behaviour. Technically , this control environment is a simplified programming environment, where the pilot is presented with a collection of programming 'primitives' of high-level tactical behaviours and world-events based on the platform's sensor system. By combining primitives into plans. the pilot can build up a sensible instruction sequence for the UAV to accomplish particular tasks in ways appropriate for the situation at hand during mission.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
