摘　　要：首先分析了工作流管理联盟的工作流元模型,结合传统工作流的建模规律和动态变化要求,对工作流元模型作了适当的改进和扩展,提出了一个支持动态特性的过程元模型,增加了对过程、活动、活动属性的动态特性描述和操作协议描述,引入了连接符、数据流以及事件、触发器和规则。可以为动态过程模型的设计提供指导,使在这个元模型之上的工作流模型具有人机交互能力和动态灵活性。In this paper, workflow meta -model of WfMC was analyzed. The meta -model was derived from the traditional laws of building model and the laws of changing,a process meta- model was proposed to guide the design of workflow process model. The process meta - model supports dynamic changes of workflow process, extensions and modifications to workflow meta -model was proposed, the meta -model describes the dynamic characteristics behaved in objects of process, activity, activity attributes, connector, data flow, affair, trigger and rule were inducted in this paper. A workflow model educed from this meta -model will possess the ability of interacting with human and the ability of handling dynamic changing.

关 键 词：工作流 工作流管理系统 元模型 动态性
