Um modelo de sistema multiagente para negociação automatizada no comércio eletrônico.

Abstract

The Internet brought new paradigms to people, for instance, the possibility to perform commercial transactions using the available communication and information technologies. In this way, many research solutions have arisen to encompass the diverse phases that compound commercial transactions for Internet systems. A particular phase present in determined contexts is negotiation, which is the focus of this work. The first proposals on automated negotiation have used agent technology to represent buyer and seller in the negotiation. These researches have generated models that have determined how the interaction between the negotiator agents is, the definition of a set of preferences for negotiation and the decision making of the agents based on these preferences. In an enterprise perspective, automated negotiation taking in consideration only a fixed and predefined set preferences has no resemblance with the real world. Based on the above, this research proposes extensions for the state-of-the-art in negotiation models. Besides this, a model for support the decision making during the negotiation is also proposed. Departing from a holistic vision of the enterprise, the decision model considers the influence of the external environment information in the negotiation process. From these models, a platform for enterprise-oriented automated negotiation is also proposed.
