摘要
通过对工作流中角色机制进行分析,在研究工作流、有向图和UML-uc模型的基础上,提出了一种有向图角色驱动的工作流建模方法。其基本思想是:在角色的驱动下,将工作流模型层次细化到原子活动,并给出其细化过程的系统总体用例模型和静态、竞争、优先、委托等角色类型的UML用例模型。借助基于用例模型的角色参与机制和动态特性,分析了过程模型内部复杂的动态关系,根据分析结果对后续更为复杂的过程模型进行有效的迭代开发。
Based on the research of workflow, directed graph and UML-uc, a directed graph - based workflow modeling method, driven by role whose mechanism is investigated in the workflow, is put forward. The essential idea is delaminating and refining the workflow modeling to the atomic activities conforming to the role, the UML-Use case model of the system which depicts the refining course and some UML - Use case models of roles including static, competitive, priority - ranked and commitment models are provided. We also explore the complicated dynamic relation within the model in virtue of role participative mechanism and dynamic characteristic of Use -case models. Furthermore, according to the result, we attempt to develop the latter part of the model that is more complicated than the former in a more efficient way.
