一种基于移动Agent的分布式DSS模型

Mobile Agent-based distributed DSS model

剖析了目前分布式决策的需求,结合面向服务的思想,应用移动Agent技术,提出了一种网格平台上的分布式决策支持系统(DSS)模型和设计思路,说明了该模型的层次结构和运行机制.这种新的模型通过引入移动Agent技术,将复杂的决策任务求解分布到网格的各节点上,实现决策问题的并行异步处理,提高了系统效率,减轻了网格负载和系统对网络带宽的依赖,并应用WebService技术利用丰富的网格决策资源,最大限度地扩展模型库,知识库和数据库,提高DSS的问题求解能力.

The requirements for present distributed decision modes were analyzed. Combined with service-oriented idea, a distributed DSS model for grid platform and its designing idea were proposed, and the hierarchy and operating mechanism of this model were explained. In this model, complicated decision tasks were distributed to different nodes on the grid platform and these tasks were solved parallelly and asynchronously by using mobile agent technology, to improve the system＇s efficiency and reduce the network＇s load and the dependence of DSS on the network＇s bandwidths. Thus, abundant resources on the grids for decision-making are exploited and the model, knowledge and data bases are expanded to the largest extend through Web Service Technology to improve DSS＇s capability Of solving problems.
