The development of distribution linguistic provides a new research idea for information group decision-making (GDM) problems, which is more flexible and convenient experts to express their opinions. However, in the process using fuzzy preference relations (DLFPRs) solve GDM there are few studies that pay attention both internal consistency adjustment external consensus experts. Therefore, this ...

A new hesitant fuzzy set (HFS)-ELECTRE for multi-criteria group decision-making (MCGDM) problems is developed in this paper. In real-world applications, the decision makers (DMs)’ opinions are often hesitant for decision problems; thus, considering the exact data is difficult. To address the issue, the DMs’ judgments can be expressed as linguistic variables that are converted into the HFSs, con...

On the one hand, there is growing need to make decisions in group at both professional and personal levels, on other it increasingly difficult for decision-makers meet same place time. The Web-based Group Decision Support Systems intend overcome this limitation, allowing contribute decision process anytime anywhere. However, they hav...

Coalition analysis is extended to incorporate uncertain preference into three stability concepts, general metarationality (GMR), symmetric metarationality (SMR), and sequential stability (SEQ) under the paradigm of the graph model for conflict resolution. As a follow-up analysis in the graph model, coalition analysis aims to assess whether equilibriums under individual calculations are vulnerab...
