Research on the bilateral negotiation algorithms of cooperative design system based on genetic algorithm

The negotiation of conflict problem in the cooperation design system was studied from the view of solving negotiation problems. A bilateral negotiation algorithm, which was based on genetic algorithm, was presented for the cooperative design system, the realizing project and step of the algorithm was designed. The Pareto solution of the negotiation problem was solved by transferring vector-optimal problems into scalar-optimal problems to support the designer to harmonize the conflict of the design project. The result shows that the method of this paper can get more Pareto solutions, which can provide more selecting chances and selecting space in the cooperative design course.
