摘　　要：针对实现资源共享和协同工作的网格技术应用研究与发展现状,提出了分层网格工作流体系结构：在设计层利用网格工作流逻辑和网格工作流语义建模网格工作流,在运行层利用网格工作流调度引擎和网格工作流实施引擎完成任务的实施,在资源层通过网格中间件和运行层交互。为支持上述结构,在(扩展)工作流网和计算网基础上,定义了扩展计算网模型。最后以实例说明了分层网格工作流建模支撑环境的具体应用。Grid is an innovative information services infrastructure to implement dynamic, distributed resources sharing and collaboration. In accordance with current state of grid application＇s research and development, a layered grid workflow architecture is proposed： modeling grid workflow in design layer with grid workflow logic and grid workflow semantic, operating task in running layer utilizing grid workflow scheduling engine and grid workflow operating engine, and grid middleware is the interface of resource layer and running layer. For supporting the architecture, an extended computing net model is defined based on （extended） workflow net and computing net. At last the environment of layered grid workflow is presented.
