| 摘要: |
| 针对目前工作流管理系统在描述能力和柔性上存在的严重不足,提出了一种基于协调理论和反馈机制的工作流建模方法.该方法扩展了传统活动网络模型,提出了新的建模机制,增加了请求、服务、协调、多实例化等新的建模元素.详细给出了扩展建模元素的实现机制和应用场景,同时还给出了两个模型实例.研究结果表明,与传统的活动网络模型相比,该建模方法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: |
| In this paper, in order to solve the problems of poor description ability and flexibility existed in existing workflow management system, a new workflow modeling method based on coordination theory and feedback mechanism is put forward. The proposed method extends the traditional activity network model and introduces the new modeling mechanism. Several new modeling elements, such as request node, service node, coordination node, and multiple instance node are added to the modeling method. The detailed realization mechanism and application scenarios are given in this paper and two examples are presented too.Research results show that compared with traditional actibity network model,the proposed method has significant asvantages in enhancing description ability,reducing model complexity,and improving system flexibility and adaptability.The proposed method has important value in designing and developing workflow management systems with high reliable,flexibility,andadaptability. |
