For the difficult of temperature controlling and coordination in the drying ovens for Automobile Body costing line system, a model of this system was set up based on the technology of multi-agent. According to this model, a negotiation based on argumentation was used to solve the contradiction in this Multi-agent system. Further more, a research about improving the quality and efficiency of Argumentation-Based negotiation was proposed, including finding out the optimal initial program of argumentation, trust-based negotiation and comprehensive using of the tactics in argumentation. Finally, with the efforts above, the temperature of the drying oven could be controlled much more intelligently and efficiently.
