A Z-number is very powerful in describing imperfect information, in which fuzzy numbers are
paired such that the partially reliable information is properly processed. During a decision …

The reliability of decision makers' judgments together with their degree of hesitancy are
often ignored in decision models. The inclusion of judgments with only triangular belonging …

Decomposed fuzzy sets (DFSs) are one of the latest extensions of intuitionistic fuzzy sets
which are introduced to express vague and imprecise information to be used in multi-criteria …

Z-numbers are expressed by a restriction function and a reliability function. In the literature, Z-
numbers have been extended by intuitionistic fuzzy sets but not by other fuzzy sets. This …

Intuitionistic fuzzy numbers incorporate the membership and nonmembership degrees. In
contrast, Z-numbers consist of restriction components, with the existence of a reliability …

To decrease the impact of ambiguity, fuzzy sets are frequently used to decide if an element
belongs to a set. Various fuzzy set extensions differ from others in how uncertainty is …

Business has a massive effect on both people and society as a whole in today's culture.
Businesses make significant contributions to humanity's general well-being and progress by …

Fuzzy sets (FSs) are a flexible and powerful tool for reasoning about uncertain situations that
cannot be adequately expressed by classical sets. However, these sets fall short in two …

Useful decisions are made based on reliable information. The concept of Z-number involves
the issue of reliability of information. Multipolar information is particularly important in …

In this paper, we introduce complex fuzzy Z-numbers (CFZNs) and pioneered a novel
extension of traditional fuzzy set theory by combining complex fuzzy sets and Z-numbers …
