Decision-making on real-world problems, including individual process decisions, requires an appropriate and reliable … decision support system. Fuzzy set theory, rough set theory, and neutrosophic set theory, which are MCDM techniques, are useful … for modeling complex decision-making problems with imprecise, ambiguous, or vague data.This Special Issue, "Multiple …
