Processes in the Internet of things can be represented by Petri net. Based on the behavior process model of Petri net, a model‐based repair method based on change domain is proposed. By using the corresponding relation of consistency analysis between source model and target model, the suspicious area of source model is first found out, and then the suspicious area is gradually narrowed by algorithm until the range of change area is finally determined and the minimum change area is found. Then, the variation areas in the model are repaired based on the compactness. Finally, the proposed method is verified and analyzed with a practical application.

通过Petri网的基于变更域的模型修复方法

物联网中的过程可以用Petri网表示。基于Petri网的行为过程模型，提出了一种基于模型的基于变更域的修复方法。利用源模型和目标模型之间一致性分析的对应关系，首先找出源模型的可疑区域，然后通过算法逐渐缩小可疑区域，直到最终确定变化区域的范围和最小变化区域被发现。然后，基于紧密度修复模型中的变化区域。最后，对所提方法进行了实际应用验证和分析。
