Abstract: By decomposing the activity in workflow meta-model into subtask and action,this paper puts forward the workflow management system model based on subtask and action,and gives the architecture and modal description of this model.The practice proves that the workflow management system which uses this model can be easier to maintain and extend.

Key words: subtask, action, Workflow Management System(WfMS)

摘要: 通过分析大量的工作流运行实例,从实际应用的角度将工作流过程定义元模型中的活动(Activity)进一步分解为子任务和动作,提出了基于子任务和动作的工作流管理系统模型——STAWorkflow。给出了该工作流管理系统模型的体系结构、形式化描述以及运行实例。初步实践证明采用该模型的工作流管理系统更容易扩展和维护,能较好地满足用户的需求。
