Most of the real life problems embroil uncertainties, imprecision and vagueness. Fuzzy multisets and Pythagorean fuzzy sets, initially suggested by Yager, are significant mathematical models to handle such real world problems. By combining these two notions, a new kind of hybrid mathematical model is exists: Pythagorean fuzzy multisets. In this study, Pythagorean fuzzy multisets approach is applied to a multi-robot system to achieve better results using less effort and less time.
