Stochastic multiple attribute decision making with Pythagorean hesitant fuzzy set based on regret theory
The objective of this paper is to present an extended approach to address the stochastic multi-attribute decision-making problem.The novelty of this study is to consider the regret behavior of decision makers under a Pythagorean hesitant fuzzy Handles/Braces environment.First, the group satisfaction degree of decision-making matrices is used to con
