In this manuscript, the technique of the generalized MULTIMOORA method is investigated
by using the concept of a T‐spherical fuzzy set (T‐SFS), which is the modified idea of a …

The q‐rung orthopair fuzzy set (qROPFS), proposed by Yager, is a more effective and
proficient tool to represent uncertain or vague information in real‐life situations. Divergence …

Normal wiggly hesitant fuzzy set (NWHFS) is a new fuzzy information form to help decision
makers (DMs) express their evaluations, which can further dig the potential uncertain …

The development of social economy has rendered the decision-making environment more
complex. To better adapt to the environment and solve practical decision-making problems …

Most real-life complex decision-making situations involve the simultaneous expressions of
numerous competing criteria and alternatives, as well as the possibility of inaccurate and …

In allusion to heterogeneous multi-criteria group decision making (MCGDM) problems with
incomplete weights and q-rung orthopair fuzzy (q-ROF) truth degrees, where many kinds of …

In this paper, we propose a hybrid concept of q-rung orthopair fuzzy soft set and hypersoft
set (HSS), called q-rung orthopair fuzzy hypersoft set (q-ROFHSS), which is used to express …

Emergency decision making is critically important for countries or communities to enhance
the effectiveness and validity of the emergency response, which can greatly lower …

We propose a new interval type-2 fuzzy (IT2F) programming method for risky multicriteria
decision-making (MCDM) problems with IT2F truth degrees, where the criteria exhibit a …

The partitioned Bonferroni mean (PBM) operator can efficiently aggregate inputs, which are
divided into parts based on their interrelationships. To date, it has not been used to …
