Abstract

In this section we will first discuss the very essence of group decision making and how fuzzy preferences can help alleviate some inherent difficulties and make models more realistic. Then, we will briefly present some tools to be used, notably how to deal with linguistically quantified statements, and with a linguistic quantifier driven aggregation.
