摘　　要：为了解决构件业务流程建模能力不足的问题,提出了一种基于工作流技术的构件模型——工作流构件模型。首先分析了工作流过程定义的组成和流程控制方法,识别出可用于构件业务流程建模的工作流元素;然后根据构件的独立性、封装性和组装性需求,选取工作流元素设计实现了工作流构件模型,并给出了应用实例。与传统的构件模型相比,工作流构件模型提高了业务流程构件的灵活性,丰富了业务流程构件的组装形式,降低了业务流程构件的复杂度,从而提高了构件的业务流程建模能力。In order to solve the problem of inadequate capacity for business process modeling of component,put forward a component model based on workflow technology workflow component model. First, analyzed the composition and flow controlling method of workflow process definition model to extract the workflow elements for business process modeling of component. Then, according to the need of independence, encapsulation and assembly of component, some workflow elements were used to design and implement workflow component model, and also presented one example. Compared with traditional component mo- del, the workflow component model improves flexibility, increases assembly methods and reduces complexity for process compo- nent. Therefore the workflow component model can improve the capacity for business process modeling of component.
