一种服务网格动态信息聚合模型及其应用

在动态、跨组织的网格环境中如何进行适应组织重构、业务变化等动态性要求的信息聚合是现实应用中亟待解决的问题．文章提出了服务网格动态信息聚合模型。从组织模型、数据模型、协作模型三个维度描述信息聚合中变化的因素．基于此模型．给出了一种支持动态信息聚合的实现框架，它能够适应网格组织结构变化、业务变化，协调人的参与，进而提高系统动态性．最后介绍了该模型及其实现框架在远程学习评价网格LAGrid中的应用情况．

A Dynamic Information Aggregation Model and Its Application in Service Grid Environment

It is a challenge to address the problem of dynamic information aggregation to meet the requirements of organization re engineering and business emergency. In this paper, a dynamic information aggregation model is proposed for service grid environment. The model comprises three child models, namely, organization model, data model and coordination model, describing the changing factors from three dimensions. Based on the model, an implementation framework is put forward to adapt the change of organization structure, to adapt the change of business, to coordinate human actions and consequently enhance system dynamics. Finally, a case study in practical Distance Learning Assessment Grid (LAGrid) environment is introduced.
