Decision Making with Pythagorean Fuzzy Preference Relations Driven by Additive Consistency
To further improve and develop traditional preference decision-making theory,inspired by the concept of additive consistency of intuitionistic fuzzy preference relations,two traditional fuzzy prefer-ence relations that can be mutually transformed into Pythagorean fuzzy preference relations(PFPRs)are constructed.On this basis,an additive consistency measure for PFPRs is defined,and a Pythagorean fuzzy preference decision-making method driven by additive consistency is designed.The effectiveness and ra-tionality of the proposed Pythagorean fuzzy preference decision-making method are numerically verified through specific cases.Theoretical analysis and numerical verification results show that the proposed deci-sion-making method of PFPRs driven by additive consistency has the advantages of clear structure,con-trollable amount of calculation,strong logic and operability,and can obtain a reasonable and effective deci-sion-making result.
