摘　　要：以Petri网作为描述流程模型的形式化方法,利用工作流的四种基本结构描述流程中活动之间的关系;结合流程模型质量维度中的拟合度、简化度、精确度和泛化度,给出了流程模型中执行序列与事件日志中迹的校准方法。通过所提出的校准动作序列与流程模型的映射方法,可以识别流程模型的问题域。通过网上购物的实例验证了方法的有效性和实用性。Petri nels were employed as a formalization method of process models in this research and the four basic structures of workflows were used to describe the relationships in the processing activities. A process describing on- line shopping was used as a running example to explain how to identify problem areas within a process model. The fitness,simplicity, precision, generalization of model quality dimensions were given concern to align execution se- quences in process models and traces in event logs. Based on the alignment move mapping,a process model was pro- posed,and the negative effect parts were identified. The validity and effectiveness of the proposed method were thus illustrated through the analysis of the online shopping examples.
