Use of intelligent software agents to play the role of supporting personnel in simulations has the potential to reduce the requirement for support staff and increase the instructor's control of the simulation. The research presented here examines the suitability of intelligent software agents to aid training of individual crewmember skills and team skills. In this evaluation, human crews, intelligent agent crews, and mixed human-agent crews performed a simulated antisubmarine mission by a CP140 Aurora maritime patrol aircraft. Mission performance was recorded and crew communications were observed and rated to determine whether the intelligent software agents could perform individual crewmember functions and whether they could provide the interaction necessary for crew coordination training. The results indicate that (1) the intelligent software agents can perform individual crewmembers' functions adequately; and (2) the intelligent software agents did not interact in a way suitable for crew coordination training. The paper concludes with a discussion of the generalizability of the results and the growth potential of intelligent software agents in crew coordination training.
