Group Decision Support System

Prism’s Group Decision Support System provides group multi-criteria decision support. The software is based on a simple weighted criteria scoring approach for MCDA problems. After developing a set of possible solutions and agreeing to a set of decision criteria, the group members weigh each criterion using a pair-wise comparison analysis. The criteria weights, solution set, and criteria set consist of a multiple criteria decision matrix. The group members assess each solution against each criterion and vote on a 1 to 9 scale. In case of disagreement, a revote is taken after group discussion. After all cells are voted, the raw worth (sum of the 1 to 9 votes) and the weighted worth for each solution are displayed.
