摘要：工作流过程模型对企业业务过程进行抽象表示，作为工作流模型的核心，它已成为当前工作流建模研究的重点。为了解决现有活动网络图建模方法对状态和条件描述能力差的问题，在模型中增加了条件约束，引进了“状态”和“条件”，提出了一种基于活动网络图的面向扩展的工作流过程模型。研究结果表明，这种模型在提高模型描述能力、降低模型复杂性、提高系统柔性及适应性方面有明显优点，对于设计开发高可靠性、柔性和适应性的工作流管理系统具有重要的应用价值。

Abstract: The business process is abstracted by workflow process model, which as the core of Workflow Model, has been greatly researched in the last few years. Aiming at solving the poor descriptions in status and conditions by activity-network-diagram, the condition-restricting was added and the “status” and “conditions” was introduced into model, a expansion-oriented workflow process model was presented on the basis of activity-network-diagram. The results indicate that the model has obvious advantages in stronging expressive power, improving system flexibility and adaptability, and it has important values in designing and developing workflow management systems with high reliable, flexibility and adaptability.
Key words: workflow; activity network diagram; process modeling
