The research activities in group decision making have dramatically increased over the last
decade. In particular, the application of multiple attribute decision-making methods to group …

Consensus reaching processes play an increasingly important role in the resolution of group
decision making problems: a solution acceptable to all the experts participating in a problem …

Cuando se busca una mayor precisión en el análisis de decisiones complejas, se hace
necesario recurrir a diferentes técnicas de la Investigación de Operaciones, particularmente …

Intuitionistic fuzzy variables are powerful tools to denote positive and negative information

This paper studies the group decision making problem with linguistic preference relations.
We first study the consensus measure between the individual preference relations and the …

The intuitionistic multiplicative preference set is one of the replacements to the intuitionistic
fuzzy preference set, where the preferences related to the object is asymmetrical distribution …

The intuitionistic multiplicative preference relation (IMPR), which takes into account both the
ratio degree to which an alternative is preferred to another and the ratio degree to which an …

This paper proposes a distance-based consensus model for fuzzy preference relations
where the weights of fuzzy preference relations are automatically determined. Two indices …

Intuitionistic multiplicative preference relations (IMPRs) have been widely applied in
decision making for their ability to efficiently express the uncertainty of information. This …

In some complex group decision making cases, the opinions of decision makers (DMs)
present random characteristic. However, it is difficult to determine the range of opinions by …
