一种多agent系统框架与协商机制研究*

从基于动态、异构网络上快速构建稳健的多agent系统出发,设计了多agent远程过程调用通信模型,定义了三种基本类型的agent,对KQML消息规范进行扩展,增加了对消息生存周期的控制,设计了双缓存消息推送器以实现agent消息的主动推送,并在WCF的基础上实现了该通信框架。针对同目标多agent协作系统提出了基于开销均衡的agent系统交互协商策略,通过实例证明相对于独立运行和基于正交互协商策略的agent系统,本协商策略可有效降低系统总开销,并可使运行负载更为均衡。

Framework of multi-agent system and consultation mechanism

Based on dynamic, heterogeneous network to quickly build robust multi-agent system, this paper designed a remote procedure call model for multi-agent communication, and defined three basic types of agent, extended KQML message specification to control message life cycle. It designed a double-cache message pusher to push agent message actively, and realized the communication framework on the basis of WCF. This paper proposed a multi-agent negotiation strategy based on cost balance for multi-agent collaboration system with same target. The example proves that, compared to the system that agents operate independently or use interactive negotiation strategy, this negotiation strategy can effectively reduce the total system cost, and can run the load more evenly.
