The subject effort is part of the AFRL Effects-Based Operations Program. The goal of this effort was the development of technology for modeling operational-level adversary target systems and centers of gravity (COG). This effort specifically focused on the cross-target systems analysis to predict direct and indirect effects. An analysis of the combination of physical (e.g. petroleum, electric power) and behavioral (e.g. leadership) COGs at the operational level models was performed and the results were incorporated in the EndState Tool. The approach employs model abstraction techniques, the development of effects indicators, and the ability to compute limited enemy workarounds. The EndState Tool combined with the AFRL Strategy Development Tool provides an effects based capability for planning, targeting and assessment.
