… approaches that use trust in group decision making scenarios is presented from three different
perspectives: (i) trust propagation; (ii) trust based opinion fusion; and (iii) trust modelling. …

… be that the trust value decreases and the distrust value increases as a result of a propagation
process. To achieve this aim, we propose a dual trust propagation operator by combining …

… A novel social network based group decision making (SN-GDM) model with experts’ …
information: trust; distrust; hesitancy; and inconsistency, is introduced. The concepts of trust score (…

… information in group decision making, we introduce the definition of relative trust degree (RTD)
in Definition 16 for the evaluation model based on social network trust and cosine …

… The novelty of this trust propagation operator resides in its … paths trust propagation model
for constructing complete trust … all trust paths to collect all trust information and penalise trust …

… To do so, by analyzing characteristics of the social network representing a decision group,
we introduce the concepts of propagation efficiency induced by limited trust propagation, as …

… trust propagation methods rarely consider the relative importance of TDs, a new trust
propagation … of TD using its reference value for the trust initiator in calculating the unknown TD, …

… model based on trust relationships for social network group decision-making problems in …
a dynamic trust propagation mode is constructed to determine the optimal trust propagation …
