一种工作流过程模型到工作流网的转换方法

为了便于非专业人员的工作流建模操作，利用Petri网现有的分析计算方法进行工作流模型的正确性分析和系统性能计算，给出了基于统一建模语言活动图的工作流过程模型建模方法，讨论了统一建模语言活动图到工作流网的转换方法，包括：非对象节点的转换、控制流边的转换、对象节点及对象流边的转换等。结合民航机场地面信息系统实例，对转换结果进行了分析。

Method of translation from workflow process model to workflow-net

In order to facilitate the Workflow (WF) modeling by laypeople, a method of workflow process modeling based on Unified Modeling Language (UML) activity diagram was proposed. The existing computing method of Petri net was utilized to analyze the validity of workflow model and calculate its performances. The translation method from UML activity diagram to WF-net was discussed, including translation of all kinds of states, decision, control flow, object, object flow, etc. Therefore, the users could build workflow model easily through UML activity diagram, and the correctness analysis and performance calculation of workflow model could be accomplished through the methods offered by Petri net. A civil airport computer information management system was discussed as an example, and its translation result was analyzed.
