Current market developments lead in several domains to new challenges in terms of production flexibility, a shortening of time-to-market and a more individualized production of ”batch size 1”. While there are learning factories addressing some of these aspects, most of them are focused primarily on the manufacturing industry and overlook the process industry. In order to fill this gap, this article presents an overview over the concept and implementation of the Process-to-Order Lab. This learning factory focuses on teaching and research in the field of digitalization and modularization applications for the process industry. Therefore, the Process-to-Order Lab acts as a starting point for the development and realization of these concepts, while supporting the process industry through technology research and high-quality hands-on training of students i.e. future employees.
