Event details

With the coming of the Industry 4.0 wave, digital representations of manufacturing systems have been promoted from marginal to central. Digital twins are not simply conceived as simulation models of their physical counterpart for off-line what-if analysis, differently they are developed as self-adaptable and empowered decision-makers timely aligned with the dynamics of the real system. Enriched from these new features, digital twins are widely recognized as the key enablers for implementation of smart manufacturing paradigm. Despite this new role, there are significant barriers for the adoption of the digital twin concept in industrial applications. In fact, the creation and update of digital twins is still a challenge because of the high skills required to use the simulation applications available in the market, the long development times, and their difficult integration with optimization and artificial intelligent packages. The frequent changes manufacturing systems encounter in their life cycle boost these issues. This talk describes a data-driven approach for generating multi-fidelity digital twins of manufacturing systems from data acquired from sensors. The approach is based on process mining techniques, tracing the objects flowing in a discrete event system allows us to discover the system topology and to automatically generate the digital twin. Being based on traces containing sensor-data, the approach enables multiple actors to jointly construct digital twins of complex systems. The approach is not limited to manufacturing, but extendable to other sectors to discover complex flows along the supply chain and back to reuse/remanufacturing/recycling in circular economies. Test cases and applications from the automotive industry are presented with the intention of quantifying the benefits of the approach, understanding its actual limitations and discussing future perspectives.
