摘　　要：联盟形成是多Agent系统的一个关键问题,主要研究在联盟内Agent间如何划分联盟效用,使得Agent更愿意形成联盟,但已有策略没有考虑到Agent的信用度,联盟内的稳定性和Agent间合作的积极性并不高。对此,本文提出了一种基于信用度的Agent效用分配策略,对退出联盟现象进行有效的控制,提高了多Agent系统的使用价值。最后通过实例证明此方法的有效性。Coalition formation is a key topic in multi-agent system. It mainly studies how to allocate utility in order to make the a-gents more willing to form coalition. However, current strategies do not consider credit in utility allocation, and they are not capable to maintain long-term, stable coalitions. This paper introduces a strategy based on credit for coalition forming. The new strategy implements allocation activity among agents according to their behavior records. It is an effective way to improve the utility of multi-agent system and to prevent unexpected withdrawal. Simulation examples show the effectiveness of this approach.
