为了进一步增强多 agent 联盟效用分配的合理性，提升联盟的稳定性，提出了一种基于评价因子行为等级更新的多 agent 联盟效用分配策略。该策略引入评价因子概念，将行为等级定性描述的 agent 行为因素通过既定方法量化为行为评价因子，agent 完成任务的能力表示为能力评价因子，结合这两种评价因子对 agent 联盟的效用进行划分，并根据 agent 完成任务情况和是否存在欺骗行为对 agent 的行为等级进行更新。理论分析和分配实验表明，新策略在满足联盟形成机制的相关要求外，增强了多 agent 联盟中效用分配的合理性。%In order to further strengthen the rationality of multi-agent system coalition a utility allocation and upgrade the sta-bility of formed coalition,this paper proposed a utility allocation strategy with evaluation factor behavior rating update.The new strategy introduced evaluation factor,quantified the behavioral factor depicted by behavior level to behavioral evaluation factor by established methodology,determined the ability of agent to complete the task as the capability evaluation factor.Fi-nally,the coalition utility allocation depended on the combination of these two factors,and updated the behavior level of agent by agent’s behavior simultaneously.Theoretical analysis and experiment show that the strategy achieves requirements of coali-tion formation mechanism,at the same time,improves the justice of utility.
