One of the investment decision making techniques is present worth analysis (PWA) and it is almost the most frequently used one. Uncertain cash flows, uncertain life, and uncertain time value of money cause the usage of a fuzzy PWA. In this paper, we develop a Pythagorean fuzzy present worth analysis method to handle the fuzzy parameters of investments. Pythagorean fuzzy sets have better powerful ability than intuitionistic fuzzy sets to model the uncertainty in investment decision making problems. We present the numerical applications of the proposed PWA method.
