摘　　要：针对目前工作流管理系统在描述能力和动态性上存在的不足,提出了一种基于构件的动态工作流建模方法。该方法扩展了传统的活动网络模型,引入了新的建模元素,提出了新的建模机制。详细描述了模型的实现机制和应用场景,同时给出了一个模型实例。与传统的活动网络模型相比,该模型方法在提高模型描述能力、降低模型复杂性、提高系统动态性及适应性方面有明显的优点,对于设计开发高可靠性、动态性和适应性的工作流管理系统具有重要的应用价值。In order to solve the problem of poor description ability and dynamic existed in existing workflow management system, a new workflow modeling method based on component is put forward. The traditional activity network model is extended and the new modeling elements and new modeling mechanism are introduced. The detailed realization mechanism and application scenarios are given and one example is presented. The research results show that compared with traditional activity network model, the proposed method has significant advantages in enhancing description ability, reducing model complexity, and improving system dynamic and adaptability. The proposed method has important value in designing and developing workflow management systems with high reliable, dynamic and adaptability.
