The α -Discounting (α-DMCDM) as an extension of AHP, TOPSIS, VIKOR, PROMETHEE, and Weighted Sum
Florentin Smarandache
The Analytic Hierarchy Process (AHP) and other classic Multi-Criteria Decision Making (MCDM) techniques excel when decision makers can provide consistent pair wise judgments. Real…
Representing Higher-Order Networks: A Survey of Graph-Based Frameworks
Takaaki Fujita, Florentin Smarandache
Many real-world phenomena can be naturally represented using graphs and networks. Classical graph models, however, are generally restricted to pairwise interactions and may therefo…
Handbook of Rough Set Extensions and Uncertainty Models
Takaaki Fujita, Florentin Smarandache
Rough set theory models uncertainty by approximating target concepts through lower and upper sets induced by indiscernibility, or more generally, by granulation relations in data t…
Survey of Various Fuzzy and Uncertain Decision-Making Methods
Takaaki Fujita, Florentin Smarandache
Decision-making in real applications is often affected by vagueness, incomplete information, heterogeneous data, and conflicting expert opinions. This survey reviews uncertainty-aw…
A Dynamic Survey of Fuzzy, Intuitionistic Fuzzy, Neutrosophic, Plithogenic, and Extensional Sets
Takaaki Fujita, Florentin Smarandache
Real-world phenomena often exhibit vagueness, partial truth, and incomplete information. To model such uncertainty in a mathematically rigorous way, many generalized set-theoretic…
Theoretical Foundations of Superhypergraph and Plithogenic Graph Neural Networks
Takaaki Fujita, Florentin Smarandache
Hypergraphs generalize classical graphs by allowing a single edge to connect multiple vertices, providing a natural language for modeling higher-order interactions. Superhypergraph…
