Abstract: | This paper applies a distributed theory of situation awareness based upon the analysis of interactions between agents (both
human and non-human) in an Airborne Warning and Control System (Boeing E3D Sentry). The basic tenet of this approach is that
agents within a system each hold their own component(s) of situation awareness, which may be very different from, but compatible
with, other agent’s view of the situation. However, it is argued that it is not always necessary to have complete sharing
of this awareness, as different system agents have different purposes. Situation awareness is regarded as a dynamic and collaborative
process that binds agents together on tasks on a moment-by-moment basis. Situation awareness is conceptualised as residing
at a system, not an individual level. Data were collected from crew-members in theE3D during a series of simulated air battles.
These data pertained to task structure, communications between the crew and the collection and analysis of crew actions at
critical decision points. All phases of operations were considered. From these data propositional networks were developed
in which key knowledge objects were identified. Analysis of these networks clearly shows how the location and nature of distributed
situation awareness changes across agents with regard to the phase of operation/air battle. |
