一种支持协同设计过程的工作流建模方法研究

Research on a Workflow Modeling Method to Support Cooperative Design Process

传统的工作流建模方法存在过程描述能力差和系统柔性不足等问题,对于目前各种复杂业务过程特别是协同工作过程往往不能准确地进行描述。针对这些问题,本文改进了传统的活动网络模型,引入了协同活动这一建模元素,增加了多实例化、流程的动态创建和修改等建模机制。实际应用表明,该建模方法提高了对协同设计过程的描述能力,降低了建模复杂度,改善了系统柔性和适应性。

For the poor description ability and flexibility, the existing workflow modeling methods can hardly describe the complex processes especially for the cooperative processes. To solve these problems, the traditional activity network model is improved and a new workflow modeling method is put forward. It introduces a new modeling element, cooperative activity node, and new modeling mechanisms such as multi - instantiation, dynamic creating and revising of the model. Application result shows that the proposed method has significant advantages in enhancing description ability, reducing model complexity, and improving system flexibility and adaptability.
