This paper presents a fuzzy constraint based model for bilateral multi-attribute agent purchase negotiations in competitive trading environments. Fuzzy constraints are used to capture requirements and to express proposals. The proposed interaction protocol is a dialogue game protocol where argumentation is used as a key mechanism to improve agreements in contrast to other fuzzy constraint based models which are limited to quantitative offers and counter-offers. A set of locutions and decision mechanisms which fire them are fully specified, so that each agent may decide its degree of cooperation and its degree of expressiveness, which in turn may have effects on the quality of the agreement. The notions of similarity and expected valuations of products are used in order to design efficient decision mechanisms. An example of a purchase scenario and a summary of statistical tests are presented to demonstrate the proposed model.
