Z-number模糊环境下考虑决策者心理行为偏好的多准则群决策方法研究OA

To address the problem of information fuzziness and reliability in multi-criteria group decision-making,and con-sidering the influence of quantifying decision-makers' psychological behavioral preferences on decision outcomes,this paper employs Z-numbers to characterize the fuzziness and reliability of expert evaluation information.The utility of decision-mak-ers is incorporated into the decision-making process,and expert evaluation information is aggregated and ranked using utility aggregation operators.Based on this,we construct a multi-criteria group decision-making model that integrates Z-numbers and incorporates the psychological behavioral preferences of decision-makers.A numerical example validates the effective-ness of the proposed model.Furthermore,using the Constant Relative Risk Aversion(CRRA)utility function as an example,it is demonstrated that decision-makers' psychological behavioral preferences significantly influence decision outcomes in a Z-number fuzzy environment.
