摘　　要：首先对网格环境的异构性进行描述,定义了关键计算域并给出其划分算法。刻画了基于多agent系统进行任务分配的机制,分析了在自主agent不同移动策略下网格各区域任务分布的不同。采用控制理论的方法加速agent的合理分布,从而可以充分利用关键计算域的异构特征。实例研究表明,提出的任务分配机制具有自配置和自优化特征,能够动态适应异构网格环境的要求。Firstly, heterogeneity of gird was featured and key computing field of grid was defined, in addition, its partition algorithm was presented. The task distribution mechanism based on multi-agent systems was described and diverse tasks distribution in areas of grid was analyzed with autonomous agents moving by different policies. Control theory methods were used to accelerate the appropriate distribution of agents in order to take advantage of the heterogeneity of key computing fields. Experiments demonstrate that the task distribution mechanism proposed can self-configure and self-optimize, also it can adapt to the heterogeneity of grid environment dynamically.
