In consensus-based social network group decision-making (SN-GDM) problems, the low
degree of harmony caused by opinion discrepancies and weak trust relationships may lead …

In opinion dynamics, some agents may exhibit the cognitive dissonance behaviors owing to
the contradictory belief, attitudes and opinions that they might confront with. This may greatly …

In social network group decision making (SNGDM), the consensus reaching process (CRP)
is used to help decision makers with social relationships reach consensus. Many CRP …

The main challenges in large scale group decision making (LSGDM) problem are how to
tackle with the great number of participants and how to achieve a common solution accepted …

The consensus model with the minimum cost (or minimum adjustments or minimum
information loss) is a powerful decision tool for consensus building in the group decision …

Consensus reaching processes are applied in group decision making problems to reach a
mutual agreement among a group of decision makers before making a common decision …

This paper proposes a robust ordinal regression feedback consensus model based on trust
relationships for social network group decision-making problems in intuitionistic fuzzy …

We propose a variant of the voter model by introducing the social diversity in the evolution
process. Each individual is assigned a weight that is proportional to the power of its degree …

Opinion dynamics is a fusion process of individual opinions based on the established fusion
rules. The existing opinion dynamics models assume that agents express and receive their …

Prior studies on opinion modeling focus on nonlinear physics or statistical physics methods,
