Graph-Based Business Process Model Refactoring

Companies are ever more interested in process-oriented organizational designs due to the competitive advantages they can achieve. Companies must therefore be able to manage their business process models and deal with quality assurance concerns, especially when business process models are mined by reverse engineering (e.g. from information systems) since it has harmful effects on the quality. For example, non-relevant and fine-grained elements or incomplete processes can be obtained. Refactoring techniques have become a widely-used method to mitigate those effects, changing the internal structure of business process models without altering its external behavior. Business process models can be transformed into graph structures since it has been proved as a more efficient way to manage information. This work presents IBUPROFEN, a set of graph-based refactoring algorithms to improve the quality of business process models. This paper demonstrates its feasibility by conducting a case study using a set of industrial business process models.
