An attitudinal trust recommendation mechanism to balance consensus and harmony in group decision making

Jian Wu, Xue Li, Francisco Chiclana, Ronald R. Yager
2019 IEEE transactions on fuzzy systems  
This article puts forward a trust based framework for building a recommendation mechanism for consensus in group decision making with interval-valued intuitionistic fuzzy information.  ...  Secondly, the attitudinal trust induced recommendation mechanism is established by a reasonable rule: the closer the experts, the higher their trust degree.  ...  ACKNOWLEDGEMENTS The authors are very grateful to the anonymous referees for their valuable comments and suggestions to improve considerably the quality of this paper.  ...

2017 Studies in Informatics and Control  
The consensus reaching process is the most important step in a group decision making scenario.  ...  In recent years, the researchers in the field of decision making have shown their interest in social networks since they may be successfully used for modelling communication among decision makers.  ...  In this contribution, the authors propose a trust induced recommendation mechanism generating personalized recommendations to the inconsistent users with the aim of achieving a high level of consensus.  ...

A fuzzy group decision making model for large groups of individuals

S. Alonso, I. J. Perez, F. J. Cabrerizo, E. Herrera-Viedma
2009 2009 IEEE International Conference on Fuzzy Systems  
To be able to obtain a good solution of consensus, the group of experts will be firstly simplified into a smaller group (using a simple clustering technique and a kind of trust network) which can then  ...  Group Decision Making (GDM) refers to the selection of an alternative from a set of feasible alternatives that better satisfies some criteria according to a group of individuals (experts).  ...  For instance, in democratic systems it is usual that the individuals delegate into a smaller group of experts to make decisions as it is usually not possible to involve everyone in each decision.  ...
