Abstract: Pythagorean fuzzy set (PFS), as a generalization of intuitionistic fuzzy set (IFS), is more suitable to capture the indeterminacy of the experts’ decision making information. This paper is designed to build new algorithm for managing multi-criteria decision making (MCDM) issue under Pythagorean fuzzy environment. First, we initiate a novel score function based Pythagorean fuzzy number (PFN). Later, we explore an algorithm for solving MCDM problem based on CODAS (COmbinative Distance-based ASsessment). Ultimately, the availability of method is stated by some numerical examples. The dominating traits of the developed algorithm, compared to some existing Pythagorean fuzzy decision making algorithms, are (1) derive a ranking without the complex process; (2) achieve the optimal alternative without counterintuitive phenomena; (3) strong ability to differentiate the optimal alternative.
