Research on Risk-analysis-based Method of Determining Participant Threshold

The contract net with confirmation protocol(CNCP) is a widely used coordination mechanism in multi-agent systems(MAS).But it can easily make the performance degrade when the number of participants and initiators increases.By setting a proper threshold of participants during the interaction between initiators and participants,it can reduce the risk of initiators and the amount of messages.How to determine the threshold becomes the key to solving the problem.Risks of both participants and initiators are analyzed,and the risk formule of participants and initiators are defined.A new method based on risk analysis(MRA) is proposed.This method solves the problem of how to determine the participant threshold.An example is given,which proves that MRA can limit the risk of participants and initiators,and reduce the amount of messages,which improves the performance of MAS.
