Group decision-making (GDM) involves considering how individuals collaborate to reach a decision. This paper presents an approach based on Z-number to address group decision-making problems. We consider three decision matrices for each group member, where three alternatives and beneficial criteria. Initially, we apply the Weighted Sum Model (WSM) to obtain solutions from each member for each alternative. Consequently, we derive individual solutions from each member, collectively forming the group’s solution to the alternatives. Next, the Ideal Solution method (ISM) is employed to assess all solutions group members propose. The results obtained affirm the effectiveness of this method.

摘要

Group decision-making (GDM) involves considering how individuals collaborate to reach a decision. This paper presents an approach based on Z-number to address group decision-making problems. We consider three decision matrices for each group member, where three alternatives and beneficial criteria. Initially, we apply the Weighted Sum Model (WSM) to obtain solutions from each member for each alternative. Consequently, we derive individual solutions from each member, collectively forming the group’s solution to the alternatives. Next, the Ideal Solution method (ISM) is employed to assess all solutions group members propose. The results obtained affirm the effectiveness of this method.
