Zusammenfassung
Predictable and unpredictable errors both pose threats to production systems and need to be addressed to avoid standstills, damages or even injuries. For this reason, we derive requirements for the structure of resilient production systems and propose an architecture to address these requirements. A decoupled interaction schema allows to reconfigure the compilation of the production system’s electrical and mechanical parts. The collaboration between its services enables the production system to automatically propose mitigation strategies in case of an unforeseen error. This is achieved by monitoring the process execution and extending the process models as well as the workflow engine to allow for dynamically addressing the executing components.
