In group decision-making, the use of Group Decision Support Systems is increasing and in some groups, a facilitator is required to improve communication among participants. The facilitator has several roles in this situation, which include helping decision makers (DMs) to decide which type of aggregation they would prefer in each decision context. Whenever DMs have different objectives regarding the same problem, they might decide a consensual decision is no longer possible. Therefore, other types of aggregation are required. Voting rules are strongly applied in this type of situation. However, the question that arises is: who should decide the voting method? In this article, a framework for choice of a voting procedure in a business decision context is used. It takes the facilitator’s preferences into account while it seeks to choose which voting procedure best suits the environment of the Group Decision Support System GRoUp Support (GRUS).
