Research on SLA negotiation in Manufacturing Grid

SLA (Service Level Agreement) negotiation plays a very important role in Manufacturing Grid. In order to solve its problem of practical application, firstly, we try the Nash negotiation method. Because the method depends on the negotiators´ utility functions, and it is impracticable to construct the different players´ utility function, we abandon it. Then we put forward the interactive multi-object negotiation method, because it can solve these negotiation problems without the negotiators´ utility functions. The method utilizes the different negotiators´ cross concessions of the different objects and seeks for the conflict bottleneck of the conflicts, and then solves the negotiation problems.
