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.

High complexity of business processes in real-life organizations is a constantly rising issue. In consequence, modeling a workflow is a challenge for process stakeholders. Yet, to facilitate this task, new methods can be implemented to automate the phase of process design. As a main contribution of this paper, we propose an approach to generate process models based on activities performed by the participants, where the exact order of execution does not need to be specified. Nevertheless, the goal of our method is to generate artificial workflow traces of a process using Constraint Programming and a set of predefined rules. As a final step, the approach was implemented as a dedicated tool and evaluated on a set of test examples that prove that our method is capable of creating correct process models.
