基于协调理论的工作流建模方法

Workflow Modeling Method Based on Coordination Theory

针对目前工作流管理系统在描述能力和柔性上的严重不足 ,本文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 ,增加了请求、服务、协调、多实例化等新的建模元素。同时还给出了一个招标与评标过程的工作流模型实例 ,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都有明显优点 ,对于设计开发高可靠性。

In order to solve the problems of low description ability and flexibility existed in current of workflow management systems, a new workflow modeling method based on coordination theory and feedback mechanism is put forward. The proposed method extends the traditional activity network model Several new modeling elements, such as request node, service node, coordination node, and multiple instances node, are added to the modeling method. An example of workflow model regarding bid and evaluation process is given. 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 flexibility and adaptability. The proposed method has important value in designing and developing workflow management systems with high reliability, flexibility, and adaptability.
