Approach for an event-driven production control for cyber-physical production systems

When the changing market environment in terms of logistical requirements is considered, production planning and control (PPS) has recently contributed significantly to fulfilling these demands. Cyber-physical production systems (CPPS) with their characteristics of decentralised organisation, real-time capability and smart data processing offer new possibilities for PPS. Consequently, this paper proposes a new event-based approach. Control loops close to the production shop floor enable a rapid identification of events. Based on an activity list, production control is able to react adequately to different events, such as machine disturbances. Finally, the developed approach for event-driven production control is implemented in a simulation.
