Abstract

Rational people must be affected by the fluctuation of subjective factors in the process of behavioral decision-making. This kind of fluctuation is the confirmatory bias. Based on the decision problem in construction management, this paper establishes a group decision support system (GFSS) based on fuzzy analytic hierarchy process, and improves the system flow through the expert clustering analysis results based on projection pursuit. Then the system is promoted and our system is applied in the actual engineering project. Finally, through the comparison of decision accuracy, it is proved that the system is obviously scientific and accurate compared with the Delphi decision method.
