Practical experiences and simple demonstrations within learning factories improve the learning process of trainees; however, being bound to a specific location is a disadvantage of learning factories that limits the target audience. Mobile demonstrators address this barrier to the dissemination of knowledge because they can be displayed at trade shows or transported to companies for on-site workshops. To fulfill the mobility requirement, demonstrators must be compact and easily transportable, therefore, abstractions of complex production-related processes are necessary while educational objectives must be maintained. This article presents a method for systematically deriving mobile demonstrators from complex production systems. The development of a demonstrator for industrial energy management systems serves as an example for the application of the developed method. In the demonstrator, a common and relatable daily process, namely brewing coffee, represents the industrial production process and a simplified energy management system is developed to visualize energy flows.
