Abstract: Multi-attribute decision-making (MADM) methods have always been considered by managers as a tool to support decision making. One of the best methods is to select based on expert opinions. In fact, providing models for aggregating the votes of voters in the group decision making is a subject that has always attracted researchers' attention. We aimed, in this paper, to present a model for aggregating the votes of voters who have been divided by the decision maker (DM) into two groups of desirable and undesirable ones. The proposed model has been explained by presenting its application while a numerical example and case study have also been provided.

Keywords: preferential voting; undesirable voter; data envelopment analysis; DEA; group decision making; multi-attribute decision making; MADM.
