摘　　要：在网格工作流系统的研究工作的基础上,设计开发了一种QoS感知的、分布式网格工作流引擎Q_GWFE,经过改进后的分布式工作流引擎能够对网格的服务质量进行自动感知,从而达到改进网格工作效率,提高网格服务质量的效果。并且对网格工作流描述语言GridBPEL进行了进一步扩充,通过添加相关QoS元素,使扩充后的语言Q_GridBPEL支持过程定义中的QoS描述需求。On the basis of the structure of a QoS aware and distributed workflow engine of shanghai scientific bureau, a framework is brought forward, which can in compliance with the environment of grid, QoS aware and distributed working flow engine （Q_GWFE）. This improved Q_GWFE can apperceive the QoS of grid, by doing this, the working efficiency of grid can be improved and grid＇s QoS enhanced. Further develop of grid working flow describing language-GridBPEL is also done, by adding QoS elements, developed language Q_GridBPEL can supply the demand of QoS description in procedure definition.
