Abstract

This chapter introduces some new distance and similarity measures for PFSs which resolve the inaccuracies observed in the existing measures. The objectives of this work are to introduce a new distance and similarity measures for PFSs, encapsulate the measures in an algorithm, and explore their applicability in some decision-making problems. Numerical experiments are supplied to ascertain the superiority of the new distance and similarity measures over the existing measures. Some decision-making problems such as students' career placement and pattern recognition represented in Pythagorean fuzzy pairs are addressed using the new distance and similarity measures coded with JAVA programming language.
