The digital era is shaped by increasingly complex business models, which are part of ecosystems, involve dependencies, integrate physical objects, and propose disruptive and innovative solutions. These business models place a strong emphasis on the interaction between humans and machines, as they require domain-specific knowledge and technical realization. The Digital Innovation Environment of OMiLAB facilitates the composition of digital ecosystems, as it builds on the notion of digital business models and employs a Digital Twin as a conceptual representation of an intelligent offering. Adequate devices and technologies will be provided for participants to experiment with, instantiate a selected modelling method, and realize an experiment based on the application scenario chosen.
