Decisional power in group decision making: A note on the allocation of group members' weights in the multiplicative AHP and SMART

Many complex decisions are made in a group environment, where the decision is made jointly by a committee or group structure. The individual group mem bers are often not equally qualified to contribute equitably to the decisio n process, or may have different saliences (desires) to influence the decis ion. A quantitative knowledge of the players' decisional power is useful fo r better understanding of the group decision process, and could even be use d in weighted voting within the group structure. We adapt the REMBRANDT sui te of decision models (multiplicative AHP and SMART) to measure decisional power in groups, and we generalise this to cater for the case where power i tself is deemed to be multidimensional in nature, and the case of uncertain subjective judgements of power amongst group members.
