Abstract

Automated negotiations require a more elaborated dialogue where agents would explain offer rejections in a general and vague way. We propose to represent the disappointment about an offer through fuzzy logic. Specifically we study two alternatives: a piece-wise fuzzy set or a linguistic label applied to each attribute of the offer. These alternatives are evaluated comparing the performance of both types of counter-offers with a classical approach based on linear programming. Therefore, the media of negotiation length, benefits and percentage of agreements allow us to conclude the accuracy of the alternatives proposed.
