This book introduces readers to the novel concept of spherical fuzzy sets, showing how these sets can be applied in practice
to solve various decision-making problems. It also demonstrates that these sets provide a larger preference volume in 3D space
for decision-makers. Written by authoritative researchers, the various chapters cover a large amount of theoretical and practical
information, allowing readers to gain an extensive understanding of both the fundamentals and applications of spherical fuzzy
sets in intelligent decision-making and mathematical programming.
