Abstract EN
As a new extension of Pythagorean fuzzy set (also called Atanassov’s intuitionistic fuzzy set of second type), interval-valued Pythagorean fuzzy set which is parallel to Atanassov’s interval-valued intuitionistic fuzzy set has recently been developed to model imprecise and ambiguous information in practical group decision making problems.
The aim of this paper is to put forward a novel decision making method for handling multiple criteria group decision making problems within interval-valued Pythagorean fuzzy environment based on interval-valued Pythagorean fuzzy numbers (IVPFNs).
There are three key issues being addressed in this approach.
The first is to introduce an interval-valued Pythagorean fuzzy weighted arithmetic averaging (IVPF-WAA) operator to aggregate the decision data in order to get the overall preference values of alternatives.
Some desirable properties of the IVPF-WAA operator are also investigated.
Based on the idea of the maximizing deviation method, the second is to establish an optimization model for determining the weights of criteria for each expert.
The third is to construct a minimizing consistency optimal model to derive the weights of criteria for the group.
Finally, an illustrating example is given to verify the proposed approach.
