Black-Litterman model with intuitionistic fuzzy posterior return

, 2016
The main objective is to present a some variant of the Black - Litterman model. We consider the canonical case when priori return is determined by means such excess return from the CAPM market portfolio which is derived using reverse optimization method.

Heterogeneous Fuzzy Group Decision‐Making Model With Mixed Criteria

Advances in Fuzzy Systems, Volume 2026, Issue 1, 2026.
Organizational decisions, often originating from diverse groups of managers with varying criteria, encounter challenges due to the inherent ambiguity in human judgments, particularly those involving preferences. This paper proposes a nuanced solution using a heterogeneous fuzzy group decision‐making method, accommodating diverse criteria based on real ...

A Decision‐Making Problem for Smartphone Selection Using Neutrosophic Distance Measures

Advances in Fuzzy Systems, Volume 2026, Issue 1, 2026.
A neutrosophic distance measure using average functions is defined, and the metric axioms are verified by discussing its properties on a neutrosophic structure. Further, the similarity measure’s axioms are also derived for the complement of the proposed distance measure.

A Generalized Interval Valued Intuitionistic Fuzzy Sets theory

Procedia Engineering, 2011
AbstractIn this paper, a novel generalized interval-valued intuitionistic fuzzy sets (GIVIFS) is presented, which is the generalization of conventional intuitionistic fuzzy sets (IFS) and interval-valued intuitionistic fuzzy sets (IVIFS). By analyzing the degree of hesitancy, this paper introduces generalized interval-valued intuitionistic fuzzy sets ...

A Novel Multicriteria Decision‐Making Approach Incorporating Pythagorean Hesitant Fuzzy Sets for Endangered Species Habitat Selection

Advances in Fuzzy Systems, Volume 2026, Issue 1, 2026.
Pythagorean hesitant fuzzy sets (PHFSs) effectively represent uncertain information in decision‐making by accommodating situations where the sum of membership and nonmembership degrees exceeds 1, provided their squared sum remains at most 1. This study proposes a novel distance measure for PHFSs and rigorously demonstrates its rationality and validity.

Interval Linguistic-Valued Intuitionistic Fuzzy Concept Lattice and Its Application to Linguistic Association Rule Extraction

Axioms
In a world rich with linguistic-valued data, traditional methods often lead to significant information loss when converting such data into other formats.

Multidimensional Topological Measure Spaces and Their Applications in Decision‐Making Problems

Advances in Fuzzy Systems, Volume 2026, Issue 1, 2026.
This paper presents a generalized framework termed the multidimensional topological measure space (MDTMS), developed through multidimensional fuzzy sets, multidimensional topology, and an associated distance measure. The suggested framework enhances traditional fuzzy models by facilitating a more nuanced representation and examination of intricate ...

The Intuitionistic Fuzzy Linguistic Cosine Similarity Measure and Its Application in Pattern Recognition

Complexity, 2018
We propose the cosine similarity measures for intuitionistic fuzzy linguistic sets (IFLSs) and interval-valued intuitionistic fuzzy linguistic sets (IVIFLSs), which are expressed by the linguistic scale function based on the cosine function.

An in-depth exploration of intuitionistic fuzzy T₀ in the context of bitopology [PDF]

Notes on IFS
Intuitionistic fuzzy topological space and bitopological space have been introduced by using the concepts of intuitionistic fuzzy sets which are the generalizations of interval valued fuzzy sets.
