The extensions of ordinary fuzzy sets such as intuitionistic fuzzy sets (IFS), Pythagorean
fuzzy sets (PFS), and neutrosophic sets (NS), whose membership functions are based on …

Pythagorean fuzzy set, initially extended by Yager from intuitionistic fuzzy set, is capable of
modeling information with more uncertainties in the process of multi-criteria decision making …

Pythagorean fuzzy sets accommodate more uncertainties than the intuitionistic fuzzy sets
and hence it is one of the most important concepts to describe the fuzzy information in the …

Subsea tunnels with sightseeing function (STSF) are valuable for integrating transportation
across different locations, particularly in cross-sea regions. Given their technical complexity …

Financial management performance evaluation (FMPE) has a significant effect on the
identifying an investment chance. We can usually consider FMPE as a multiple attribute …

By using Pythagorean fuzzy set (PFS), people can quantitatively describe and process
information with fuzziness, and then make reasonable and effective judgments or decisions …

The Pythagorean fuzzy set (PFS) is one of the most important concepts to accommodate
more uncertainties than the intuitionistic fuzzy sets, fuzzy sets and hence its applications are …

Pythagorean fuzzy set (PFS) is an extension of the intuitionistic fuzzy set. It has a wider
space of membership degrees. Thus, it is more capable in expressing and handling the …

Pythagorean fuzzy sets are an extension of the intuitionistic fuzzy sets, and it also
overcomes the limitations of the intuitionistic fuzzy sets. The entropy of a Pythagorean fuzzy …

Since intuitionistic fuzzy set only deals with uncertainty but not periodicity, therefore to
overcome, this situation complex intuitionistic fuzzy set is a better tool that deals with both …
