• A Complex q-Rung Hybrid Fuzzy Set with Applications 

  Unknown author (Korean Institute of Intelligent Systems, 2026-09)

  Fuzzy set theory provides a rigorous framework for modeling uncertainty and imprecision in complex systems. This study introduces a novel set, termed the Complex q-Rung Hybrid Fuzzy Set (Cq-RHFS), by integrating q-Rung ...
• Novel Application of True-False Structures in Semigroups 

  Unknown author (Korean Institute of Intelligent Systems, 2026-09)

  As a direct generalization of intuitionistic fuzzy sets (IFSs) and interval-valued fuzzy sets (IVFSs), Borzooei et al. (2020) presented and examined the concept of True-False structures (TFSs). In this article, we apply ...
• Solving Intuitionistic Fuzzy Quadratic Riccati Differential Equations using Modified Daftardar-Gejji and Jafari Methods. 

  Unknown author (Korean Institute of Intelligent Systems, 2026-09)

  Fuzzy differential equations are an important tool for modelling real-world phenomena involving uncertain quantities. In this paper, A modified fuzzy Daftardar-Gejji and Jafari method is discussed and implemented for the ...
• Comparative Performance of Classical and Fuzzy Multi-Criteria Decision-Making Methods in Healthcare Supplier Selection 

  Unknown author (Korean Institute of Intelligent Systems, 2026-09)

  Supplier selection is a critical decision-making problem in healthcare supply chain management (SCM) due to the presence of multiple conflicting criteria and uncertainty in expert judgments. This study aims to compare the ...
• Heuristic Methods for Period Detection in Time Series: A Fourier Transform-Based Approach 

  Unknown author (Korean Institute of Intelligent Systems, 2026-09)

  Time series occupy a crucial role in various fields such as finance, health, and meteorology. Identifying periodic patterns and trends within these time series is a significant task. In this paper, we introduce a novel ...
