Systems and methods are provided for evaluating a plurality of courses of action according to a plurality of decision factors. A system memory contains a decision model comprising a plurality of global influence values and the plurality of courses of action. Each course of action has an associated set of decision parameters corresponding to the plurality of decision factors. An input device is operative to receive input from a user to adjust the values of the global influence values. A computational engine calculates a fitness parameter for each course of action based on the set of decision parameters for the course of action and the global influence values. The computational engine is operative to update the decision model in real time to reflect input from the user interface. A display displays the decision model to the user.
