With respect to the multi-attribute decision making problem in which expert evaluation information is Pythagorean fuzzy number and attribute information is interrelated, the generalized Pythagorean operation rules are first defined. Combining with geometric Heronian mean, a Pythagorean Fuzzy Geometric Heronian Mean(PFGHM) operator is proposed. Then, a new Pythagorean fuzzy cross-entropy is designed based on logarithmic function. Finally, a Pythagorean decision-making model based on PFGHM operator and cross-entropy is constructed, and the reliability of the model is verified by an example of selecting talent teams in universities.

Key words: multi-attribute decision making model, Pythagorean fuzzy sets, geometric Heronian mean, cross-entropy, closeness degree
