Robust Portfolio Selection with Distributional Uncertainty and Integer Constraints
This paper studies a robust portfolio selection problem with distributional ambiguity and integer constraint. Different from the assumption that the expected returns of risky assets are known, we define an amb...

Novel consistency and consensus of generalized intuitionistic fuzzy preference relations with application in group decision making
Preference relations are an efficient technology to derive the priority vectors for the alternatives in group decision-making. In this paper, an analysis of the existing research on group decision-making with ...

A novel additive consistency for intuitionistic fuzzy preference relations in group decision making
Deriving the priority vectors of the alternatives from preference relations is an interesting research topic for group decision making with preference information. This paper uses an example to show that the r...

The Aviation Technology Two-Sided Matching with the Expected Time Based on the Probabilistic Linguistic Preference Relations
The two-sided matching has been widely applied to the decision-making problems in the field of management. With the limited working experience, the two-sided agents usually cannot provide the preference order ...

Computation of generalized linguistic term sets based on fuzzy logical algebras for multi-attribute decision making
Computational models of various linguistic term sets whose evaluation scales are the identity functions have been extensively investigated. Among these models, although the virtual linguistic model is the most...

Derivatives and differentials for multiplicative intuitionistic fuzzy information
By using the unsymmetrical scale instead of the symmetrical scale, the multiplicative intuitionistic fuzzy sets (MIFSs) reflect our intuition more objectively. Each element in a MIFS is expressed by an ordered...

Consensus-reaching methods for hesitant fuzzy multiple criteria group decision making with hesitant fuzzy decision making matrices
Group decision making plays an important role in various fields of management decision and economics. In this paper, we develop two methods for hesitant fuzzy multiple criteria group decision making with group...

Hierarchical hesitant fuzzy K-means clustering algorithm
Due to the limitation and hesitation in one’s knowledge, the membership degree of an element to a given set usually has a few different values, in which the conventional fuzzy sets are invalid. Hesitant fuzzy ...

A method for estimating criteria weights from intuitionistic preference relations
An intuitionistic preference relation is a powerful means to express decision makers’information of intuitionistic preference over criteria in the process of multi-criteria decision making. In this paper, we f...
