CONSENSUS BUILDING IN A GROUP DECISION-MAKING PROCESS

ABSTRACT Expert agreement is a key issue for consensus building process; appropriate methods and tools are needed to support an efficient group decision-making process. This study presents a combination of Analytic Hierarchy Process (AHP) with the Delphi method as a useful support for group decision-making processes aimed at consensus building. A new methodology that includes stability and exclusion analysis; as well as new coefficients of concordance and consistency with a statistical approach are proposed through a case study to explore the consensus building in the group decision-making process.
