摘　　要：在MAS的分布合作求解和任务分配中,合同网模型被广泛应用,但是传统的合同网模型存在一定的缺点。文章首先介绍和分析了传统模型存在的不足,将Agent联盟引入到合同网模型,有效地结合了合作性和竞争性,能够合理调配Agent来提高系统的协作效率,同时提出了任务光荣榜的概念,有效地降低协商时间和通信流量,提高了系统效率。最后给出了改进模型在农业综合信息服务平台上的成功应用,改进模型能显著降低MAS系统平均响应时间,提高客服满意度。The contract net model is widely used for distributed problem solving and task allocation in MAS,but it has some disadvantages. Firstly, this paper describes and analyzes the traditional model＇s shortcomings, Agent-alliance is introduced into traditional model,which effectively combine competitive with cooperation and able to reasonably allocate agent and improve collaborative efficiency for system.Meanwhile, honour roll for task is proposed,it reduces cost of communication, and can compute effectively during negotiation.
