Hesitant fuzzy set turns out to be a powerful tool in expressing uncertainty and vagueness.
Liao and Xu (J Intell Fuzzy Syst, 26: 1601–1617, 2014b) proposed a family of hesitant fuzzy …

Hesitant fuzzy set, as a new generalized type of fuzzy set, is an efficient and powerful
structure in expressing uncertainty and vagueness and has attracted more and more …

Decision making always happens in our daily life, for example, choosing a car to buy, or
selecting an electronic product from Amazon or Ebay. In the traditional multiple criteria …

Interval‐valued hesitant fuzzy set (IVHFS), which is the further generalization of hesitant
fuzzy set, can overcome the barrier that the precise membership degrees are sometimes …

Purpose–The purpose of this paper is to present some dynamic hesitant fuzzy aggregation
operators to tackle with the multi-period decision-making problems where all decision …

In this paper, we extend the Hamacher operations to aggregate the dual hesitant fuzzy
elements (DHFEs). Firstly, operational rules of DHFEs based on Hamacher t-norm and t …

As a generalization of fuzzy sets, hesitant fuzzy set is a very useful technique to represent
decision makers' hesitancy in decision making. Various hesitant fuzzy weighted operators …

The dual hesitant fuzzy set is an efficient mathematical approach to study imprecise,
uncertain or incomplete information or knowledge. In this paper, we study the aggregation …

In this study, two induced generalized hesitant fuzzy hybrid operators called the induced
generalized hesitant fuzzy Shapley hybrid weighted averaging (IG-HFSHWA) operator and …

When people make a decision, they are usually hesitant and irresolute for one thing or
another which makes it difficult to reach a final agreement. For example, two decision …
