This paper proposes a group decision-making (GDM) method for integrating heterogeneous
information. To avoid information loss, instead of transforming heterogeneous information …

In recent years, the “Belt and Road” has aroused great attention of international society. It

The use of hesitant information in pairwise comparisons enriches the flexibility of qualitative
decision making and allows for hesitant fuzzy linguistic preference relation (HFLPR). This …

In this paper, two new techniques, linguistic fuzzy simple additive weighting (FSAW) and
linguistic fuzzy technique for order of preference by similarity to the ideal solution (FTOPSIS) …

In the real world the decisions are frequently made by a group of decision makers. Methods
to support group multicriteria decision making (MCDM) in dynamic environments is a …

Intuitionistic fuzzy preference relations (IFPRs) are used to deal with hesitation, while
interval-valued fuzzy preference relations (IVFPRs) are for uncertainty in multicriteria …

Group decision making has been widely studied since group decision making processes are
very common in many fields. Formal representation of the experts' opinions, aggregation of …

In group decision making (GDM) with intuitionistic fuzzy preference relations (IFPRs), the
consistency and consensus are two key issues. This paper develops a novel method for …

Measuring consistency of preferences is very important in decision-making. This paper
addresses this key issue for interval-valued reciprocal preference relations. Existing studies …

Interval fuzzy preference relations (IFPRs) that can simply denote the lower and upper
bounds of decision makers' uncertain judgments are keenly studied by researchers and are …
