摘要: Several choice processes of alternatives for non-homogeneous group decision-making problems, assuming linguistic preference relations expressing the opinions individuals and values their respective power or importance degrees, are presented. These designed using two degrees based on concept fuzzy majority: quantifier guided dominance degree non-dominance degree, being last one a generalization Orlovski's non-dominated alternative concept. In order to deal with non-weighted information, ordered weighted averaging (LOWA) operator is applied. To three operators information aggregation used: disjunction (LWD) operator, conjunction (LWC) (LWA) operator.
