ChoiceResults is a decision support software application for modeling and analysis tool using the analytic hierarchy process (AHP) for modeling complex decisions and analyzing the results. ChoiceResults models the decision based on a set of objectives and criterion that are "brainstormed" and organized using a whiteboard. The objectives and criteria are evaluated using a pair-wise rating resulting in the decision weights. The alternatives are evaluated against each criterion to determine the results. The result are shown graphically and are evaluated by analyzing the contributing factors and the sensitivity of those factors to the decision. ChoiceResults provides group collaboration tools for group ratings and deriving concensus among the group. The results of the group collaboration is used to set the pair-wise ratings of the criteria and alternatives resulting in a group concensus decision.
