A new Tactical Group Decision Analysis System (TGDAS) combining analytical and naturalistic decision modeling

The tactical group decision aiding system supports co-located or distributed teams who are planning missions requiring the selection of one among several possible options. Team members propose courses of action by creating scenarios, i.e., causally linked sequences of actions, key factors or events in the past, present, or future, and short or long-term mission outcomes. The TGDAS builds formally correct decision models via a scenario matrix that compares scenarios and identifies significant branch points, and by means of pre-stored editable templates that supply variables and relationships matching the scenario branch points in the relevant type of mission and situation. Model-based analyses order the options and let the collaborative team focus on variables that have the most impact on decisions and outcomes.
