Abstract

In this study, we first introduced the spherical fuzzy Z-numbers (SFZNs) and developed some basic operational rules. SFZNs can be used effectively to make true ambiguous judgments, reflecting the fuzzy nature, flexibility, and applicability of decisions making data. Furthermore, we developed some spherical fuzzy Einstein Z-number weighted averaging/geometric aggregation operators and their important axioms. Finally, We developed the algorithms based on the proposed operators to tackle the uncertain information in decision-making problems. Finally, I developed the relative comparison and discussion analysis to show the practicability of the technique.
