Group decision-making process can result in enriched decisions compared to individuals because group members can contribute more knowledge and a diversity of perspectives.
Having this diverse pool of stakeholders makes having a unanimously agreed decision seems an impossible task.
One practical solution is to resolve the conflict and reach a consensus decision in which affected parties (stakeholders) seek to reach an agreement on a course of action to address a problem.
This research attempts to develop various decision support systems based on MCDM and optimization methods to address the conflict resolution problem in a Group Decision-Making (GDM) process.
