Business Process Recomposition as a Way to Redesign Workflows Effectively

Business process models are subject to changing requirements. The purpose of this paper is to present methods that enable computer-aided recomposition of process models, understood as using existing processes to design new ones. This procedure involves dividing existing BPMN diagrams into smaller components, from which new models can be created. This kind of model generation can be performed manually by the user or run automatically, based on the Constraint Programming technique. The presented algorithms can improve the process of model redesign and allow users to avoid typical anomalies that may occur in the modeling phase.
