Resumen de Opinion Changing Aversion Functions for Group Settlement Modeling

Matteo Brunelli, Robert Fullér, József Mezei

• Opinion changing aversion (OCA) functions are used to quantify the decision makers’ resistance to opinion changing. By introducing OCA functions of polynomial form we will show that if each expert has a quadratic opinion changing aversion function then the minimum-cost solution is nothing else but the weighted average of the individual optimal solutions where the weights are the relative importances of the decision makers. We will consider minimum-cost solutions for group settlements under crisp and fuzzy budget constraints.
