  Pythagorean fuzzy sets provide stronger ability than intuitionistic fuzzy
sets to model uncertainty information and knowledge, but little effort has been
paid to conflict analysis of Pythagorean fuzzy information systems. In this
paper, we present three types of positive, central, and negative alliances with
different thresholds, and employ examples to illustrate how to construct the
positive, central, and negative alliances. Then we study conflict analysis of
Pythagorean fuzzy information systems based on Bayesian minimum risk theory.
Finally, we investigate group conflict analysis of Pythagorean fuzzy
information systems based on Bayesian minimum risk theory.
