Consensus decision-making method and application based on psychological discrepancy measurement
In response to the current deficiency in existing research on group consensus,which often overlooks the relationship between decision-makers'psychological perception and actual evaluation differences,this paper proposes a consensus decision-making method based on psy-chological discrepancy measurement.Firstly,spatial distance measurement and ordinal mea-surement are introduced,upon which a linear programming model is constructed to determine the optimal weights of decision-makers.Secondly,Weber-Fechner's psychophysics laws are ex-tended to the process of group consensus,introducing the concept of psychological discrepancy based on group decision-making and defining the psychological discrepancy measurement.This measurement effectively captures the subjective perceptions of decision-makers regarding evalu-ation differences,thereby quantifying their acceptance of the group opinions.Furthermore,the concept of psychological threshold is proposed,along with a method to determine the psycho-logical threshold.The proposed psychological threshold is objectively determined based on the decision-making environment and accommodates the varying threshold requirements for different evaluation levels.Subsequently,an adjustment feedback mechanism based on the psychological threshold is designed.Finally,the feasibility and effectiveness of the proposed method are vali-dated through a case study and comparative analysis on the evaluation of the logistics company's level of intelligence.
