A Pythagorean fuzzy VIKOR method is proposed to solve the problem of VIKOR multi-criteria group decision making in complex uncertain environment.First of all,the decision information is transformed into the Pythagorean fuzzy number(PFN),and the expert evaluation information is aggregated by the Pythagorean fuzzy cross influence ordered weighted average operator(PFIOWA).On this basis,the weight of the criterion is calculated based on the G1-CRITIC method,which combines subjectivity and objectivity,and evaluated by the Pythagorean fuzzy VIKOR method.Finally,the feasibility and effectiveness of the method are verified by taking the service quality evaluation of highway freight transportation enterprises as an example.
