基于数据流的模型变化域分析

Analysis of Model Change Region Based on Data Flow

提出一种新的方法来分析模型变化域,即在业务流程Petri网和数据约束下的业务流程Petri网基础上,抽象分离控制流Petri网模型和数据Petri网模型,并在没有目标模型且数据出现变化的情况下,根据数据信息对业务流程的影响,寻找业务流程的变化域。这一方法在一定程度上矫正了当前研究较多地考虑控制流对业务流程的影响,而忽略数据流影响的不足,对流程模型的完善具有一定参考价值。

This paper introduces a new method to analyze the model change region. We separated the Petri net model of control flow and data flow based on business process in Petri Net and the constraint of business process Petri Net. We tried to search for the change region of business process under the circumstance that there is no objective model and the data is unstable, while the data information is also being concerned. This research method can more or less rectify the influence of control flow toward business process, ignore the influence of data flow and finally be helpful for refining the process model.
