This paper proposes a new group decision making (GDM) approach in the environments of
interval-valued intuitionistic fuzzy values (IVIFVs). Firstly, we propose a new score function of …

A bstract In this paper, we propose a new method for multiple attribute group decision
making (MAGDM) based on the proposed interval-valued intuitionistic fuzzy aggregation …

The development of information measures associated with interval-valued intuitionistic fuzzy
values (IVIFVs) has been an important research area over the past few decades. In the …

In this paper, we introduce a new operator called the continuous interval-valued intuitionistic
fuzzy ordered weighted averaging (C-IVIFOWA) operator for aggregating the interval-valued …

Interval-valued intuitionistic fuzzy sets (IVIFSs) contain three ranges, namely the
membership degree range, the non-membership degree range, and the hesitancy degree …

In this paper, we investigate the multiple attribute group decision making (MAGDM)
problems, of which the attribute values in the group decision matrices provided by each …

Efficient aggregation methods and order relationships are crucial in solving group decision
making (GDM) problems with linguistic interval-valued Atanassov intuitionistic fuzzy …

This study investigates the group decision making under interval-valued intuitionistic fuzzy
environment in which the attributes and experts are in different priority level. We first propose …

An important research topic related to the theory and application of the interval-valued
intuitionistic fuzzy weighted aggregation operators is how to determine their associated …

Many operators have been developed for aggregating interval-valued intuitionistic fuzzy
information. However, the existing interval-valued intuitionistic fuzzy aggregation operators …
