A primary task of the Future Combat Systems (FCS) program is development, production, integration, implementation, and sustainment of decision aiding Planning and Decision Aids (P&DA). These will enable Command and Control (C2) system in making accurate decisions and schedule control commands in a quick and timely manner using large amounts of data from disparate sources. We created a preliminary Advanced Decision System (ADS) as a man-machine decision interface for such large and complex situations. The ADS incorporates the mechanisms needed to assure robust decision-making performance, while enabling human intervention for difficult problems at appropriate times.
