Abstract: Complicated and dynamic environment of the grid requires urgently supporting of autonomic paradigim.The paper proposes a new architecture of grid with autonomic computing feature.Autonomic grid service layer，autonomic multi-agent collaboration layer and policy layer that can express user needs accomplish self-managing function of the grid.In order to well implement the autonomic cooperation of agents，the paper presents the algorithm of constructing similarity-association tree of multi-agent.Running of grid prototype system implemented in the simulation environment shows that grid system with above architecture has abilities of self-configuration，self-optimization，self-protection and self-healing.

Key words: autonomic computing, grid architecture, autonomic grid service, multi-agent, policy, similarity-association tree

摘要： 网格环境的复杂性和动态性迫切需要自主计算范型的支持。提出了一种具有自主计算特征的新型网格体系结构。网格的自我管理功能通过自主网格服务层、多Agent自主协同层和表达用户需求的政策层来完成。为了更好的实现Agent间的自主协同，提出了构造多Agent相似-关联树的算法。模拟环境下实现的网格原型系统的运行表明，符合该体系结构的网格系统具有一定程度的自配置、自优化、自保护和自愈合的能力。
