A Model to Minimize Disagreement in Group Decisions with Consensus

Abstract

The group decision making (GDM) is a procedure where a chance is given for team members to impact
a decision. Therefore, team members feel obligated to the decision that is made, such a decision-making
procedure needs some degree of consensus. Decision making problems mainly involve discovering the
best option from a feasible alternative set. We devise an integer program model for facing the difference
between everyone’s preferences and the final solution. The consensus degree can be discovered to
reveal how far a group of individuals is from maximum consensus. The model is created in order to
minimize the disagreement of the consensus obtained.
