    Group decision-making based on heterogeneous preference relations with self-confidence
    (Springer, 2016-11-29) Chiclana, Francisco; Herrera-Viedma, Enrique; Cabrerizo, F. J.; Dong, Yucheng; Liu, Wenqu
    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 relations. In this study, we define the preference relation with self-confidence by taking multiple self-confidence levels into consideration, and we call it the preference relation with self-confidence. Furthermore, we present a two-stage linear programming model for estimating the collective preference vector for the group decision-making based on heterogeneous preference relations with self-confidence. Finally, numerical examples are used to illustrate the two-stage linear programming model, and a comparative analysis is carried out to show how self-confidence levels influence on the group decision-making results.

    A new type of preference relations: Fuzzy preference relations with self-confidence
    (IEEE, 2016) Chiclana, Francisco; Herrera-Viedma, Enrique; Cabrerizo, F. J.; Liu, Wenqu; Dong, Y.
    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. In this study, we propose a new type of preference relations: fuzzy preference relations with self-confidence. A linear programming model is proposed for estimating priority vectors of this new type of preference relations. Finally, two numerical examples are provided to demonstrate the linear programming model, and a comparative analysis is used to show the influence of self-confidence levels on the decision-making results.
