摘　　要：网格工作流是将工作流技术应用到网格环境中。研究了在OGSA框架下,网格工作流的概念、特点,基于OGSA工作流层次结构和网格工作流执行的基本过程,提出了网格工作流研究中所要解决的几个关键问题,包括网格工作流描述语言、规划与调度、执行与管理、监测与错误处理、动态与优化处理、使用与开发环境。Grid workflow is the application for the workflow in the grid environment. The conception, characteristic, hierarchy based on OGSA and the basic execution process of grid workflow on the OGSA framework were researched, and several key issues in the research for grid workflow were brought forward, including description language of grid workflow, programming and regulating, execution and management, inspection and error handling, handling dynamically and optimization, using and development environment etc.
