基于Agent自组织机制的服务组合

Service Composition Based on Agent Self-organization

在多Agent系统中,Agent之间通过互相协商提供复合服务.由于存在大量功能相近,类型相似的服务,如何选择适合的Agent(其所代表的服务主体)来进行服务组合成为一个关键问题.面对服务质量以及外界需求的动态变化,本文提出一种基于伙伴(Friend)策略的Agent自组织算法,并实验模拟了该算法的性能,与之前的算法相比在复合服务质量以及通讯开销量上都有了不错的提高.

In multi-agent systems,agents collaborate with each other to provide compound service.As there areabundant similar service resources in the web,it′s a key problem to choose the appropriate agent（the serviceentity it represents）.Through the experiment simulation,an agent self-organize algorithm based on Friendstrategy is proposed in this article.Compared with previous algorithms,our experiments results show that thisalgorithm performs effectively on improving compound service quality and reducing communication cost.
