Group decision-making based on heterogeneous preference relations with self-confidence
Preference relations are very useful to express decision makers’ preferences over alternatives in the process of group decision-making. However, the multiple self-confidence levels are not considered in existing preference ...
Average-case consistency measurement and analysis of interval-valued reciprocal preference relations
Measuring consistency of preferences is very important in decision-making. This paper addresses this key issue for interval-valued reciprocal preference relations. Existing studies implement one of two di erent measures: ...
Modeling Influence In Group Decision Making
Group decision making has been widely studied since group decision making processes are very common in many fields. Formal representation of the experts’ opinions, aggregation of assessments or selection of the best ...
GDMR A new framework in R to suppot Fuzzy Group Decision Making processes
This is a summary of our article published in Information Science  to be part of the MultiConference CAEPIA'15 KeyWorks.
Soft consensus models in group decision making
In group decision making problems, when a consensual solution is required, a natural question is how to measure the closeness among experts’ opinions in order to obtain the consensus level. To do so, different approaches ...
An opinion control rule with minimum adjustments to support the consensus reaching in bounded confidence model
Opinion dynamics provides a modeling tool for the public opinion management. The existing studies mainly focused on building the evolution model of opinions. However, the control of public opinions has been a key problem ...
A new type of preference relations: Fuzzy preference relations with self-confidence
Preference relations are very useful to express decision makers’ preferences over alternatives in the process of decision-making. However, multiple self-confidence levels are not considered in existing preference relations. ...
Choice degrees in decision-making: A comparison between intuitionistic and fuzzy preference relations approaches
Preference modelling based on Atanassov’s intuitionistic fuzzy sets are gaining increasing relevance in the field of group decision making as they provide experts with a flexible and simple tool to express their preferences ...
