A New MADM Approach in Building Consensus in Delphi’s Technique

There is no doubt that Delphi is a powerful technique in group decision-making context. Despite its usefulness, Delphi has some limitations too. A major drawback is the lack of transparency in reaching the consensus among the respondents. Therefore, in this paper, to resolve this limit, a new mathematical approach (based on the improved AHP models) according to Asgharpour (2003) and Azadfallah and Azizi (2015), is proposed, and can more assure the results by applying a model. A numerical example (in technologies foresight fields) demonstrates the application of the proposed method. The findings in this paper confirm the effectiveness of proposed method.
