Interval type-2 fuzzy sets are useful and valuable for depicting uncertainty and managing
imprecision in decision information. In particular, interval type-2 trapezoidal fuzzy numbers …

Deriving the fuzzy priorities of criteria from pairwise comparison results is a challenging task
in fuzzy multi-criterion decision-making problems. Most past work accomplishes this task by …

To encompass decision data vagueness, many researchers generalized multi-criteria
decision-making (MCDM) methods in certain environment into fuzzy multi-criteria decision …

In the present paper, we define an improved possibility degree method to rank the different
intuitionistic fuzzy numbers (IFNs). To achieve it, we first present some shortcomings of the …

With the development of social and economic research, the judgements that people deal
with are full of fuzziness and vagueness. It is convenient to use the linguistic q-rung …

The paper considers the multi-criteria decision-making problem based on linguistic picture
fuzzy information. Firstly, we propose the concept of linguistic picture fuzzy set (LPFS) …

As information continues to expand and uncertainty intensifies, traditional three-way
decision methods in multi-criteria environments often appear inadequate when dealing with …

An extension to the fuzzy multiple criteria decision making (MCDM) model is suggested in
this work, where the ratings of alternatives versus criteria, and the importance weights of all …

In the elicitation of decision makers' fuzzy and uncertain assessments, linguistic terms are
natural and efficient as the preference modeling tools. Although the linguistic variables are …

Decision making is a process for managing the decision problem for human beings that use
linguistic information. However, it is sometimes limited by the fact that the linguistic models …
