摘　　要：针对传统表单和基于VC的图形化建模工具的局限性,依据工作流管理联盟提出的工作流参考模型中的接口1,提出了基于Web技术的工作流图形化建模工具体系结构,分为应用层、业务逻辑层、数据访问层和数据层。给出了业务逻辑层图元的图标及相关属性,采用JavaScript实现了应用层界面组件对模型库、资源库、组织库和表单库的调用,可视化流程定义模型最终以XML文件存储。该建模工具可方便流程设计者定义流程,实现对流程访问控制的设置,目前已应用于住院医师规范化培训系统中,证明了该设计方案的可行性和实用性。Against the limitations of traditional form and VC-based graphical modelling tools, the architecture of web-based workflow graphical modelling tool was proposed according to the interface I of workflow reference model which was brought forward by Workflow Management Coalition. This architecture included the application layer, business logic layer, data access layer and data layer. The icons and correlative properties of the elements in business logic layer were given. The invoking methods of interface components on application layer for the model base, resources base, organisation base and form base were realised by JavaScript, and the visualised process definition models were stored with XML files eventually. This modelling tool can facilitate the process designers to define process and set process access control, which was already applied to the standard training system of resident physicians, and its feasibility and practicability were certified.
