The minimum cost consensus model (MCCM) aims at reaching group consensus for either
conflict or polarized opinions evaluated in group decision making. Decision makers (DMs) …

In minimum cost consensus problems, to accomplish the group consensus, decision makers
accommodate their initial discrepant opinions based on the unit adjustment costs. During …

Minimum-cost consensus (MCC) using the optimization-based consensus rule (OR) has
been developed and widely applied to various group decision-making (GDM) contexts …

In group decision-making processes, decision makers may have different risk preference
types, which usually make them take various responses to the same problem. In minimum …

This paper mainly focuses on the consensus problem with utility preferences denoted by
simple trapezoidal membership function. In group decision-making (GDM), for acquiring the …

In complex group decision making (GDM), reaching a consensus needs both the adequate
communication and exchange between the individual decision makers (DMs) and the input …

Consensus reaching process (CRP), as an essential part of group decision making (GDM),
can facilitate more effective consensus by taking human behaviors into account. Extending …

Abstract Agreement in Group Decision-Making problems has recently been tackled through
the use of Minimum Cost Consensus (MCC) models, which are associated with solving …

In the consensus reaching process, the moderator, as the representative of collective
interests, needs to consume certain resources to help decision-makers (DMs) reach a …

Since the hard consensus is difficult and costly to achieve in group decision making (GDM),
it is reasonable and necessary for decision makers (DMs) to reach a soft consensus within a …
