Multi-attribute negotiation model based on internal factors argumentation

In automated multi-attribute negotiation, negotiation agent can get a better deal by using heuristic methods to make effective tradeoff or concession between different attributes. In this paper, we proposed a multi-attribute negotiation model based on internal factors argumentation which allows exchanging private information as argumentation, and then can reach ideal results without complex computation. Firstly, the negotiation problem definition was introduced. Secondly, negotiation protocol and argumentation ontology structure were defined. Thirdly, we focused on the negotiation strategy and algorithm about how agents react in the negotiation process, such as made proposals and argumentations. Experiment showed that Pareto efficiency and good social welfare results were reached through the exchange of internal factors of negotiation.
