为了克服传统工作流管理系统的不足，设计了工作流管理型系统的原型体系结构，搭建了轻量级工作流引擎的核心架构，详细地介绍了轻量级工作流引擎各个组件及功能，该架构能根据需要灵活地添加和裁减各种组件来扩展工作流引擎的功能，也可以根据具体需求灵活地定制到不同领域的工作流管理系统中。 　　Abstract: 　　In order to overcome the deficiency of traditional workflow management system， this paper designs prototype framework of workflow management system and builds core framework of lightweight workflow engine， also elaborates various components and functions of workflow engine. According to specific needs， the core framework allows flexible addition and reduction of various components to expand the workflow engine function， also flexibly customs to different areas of workflow management system.
