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

Design and Implementation of a Decision Support System for Production Scheduling in the Context of Cyber-Physical Systems

“…To realize the detection of deviations and their impacts, the DSS must analyze the acquired production data (FR dod [1][2][3][4]. This again includes the four data types [38]. The identified events must then be categorized (FR dod 5) in order to present the cause of the events and to be able to react to the events [22,39].…”

“…Exemplary event categories may include machine breakdowns or deviating set-up and production times. Furthermore, the system needs to display the categorized events to the user (FR dod 6) [38]. For each of the detected events, the impacts must further be determined (FR dod 7) and indicated to the user (FR dod 8; e.g., downtime of a machine) [38].…”

However, this should not only be limited to the descriptive facts of the event, but also consider the effects on the current production (e.g., a delay in the current production step leads to delayed order completion).…”

“…However, this should not only be limited to the descriptive facts of the event, but also consider the effects on the current production (e.g., a delay in the current production step leads to delayed order completion). Finally, it must be examined for each event whether it impairs or prevents the feasibility of the current schedule (FR dod 9) [38]. If the current schedule can no longer be fulfilled, the DSS must present corresponding information (FR dod 10) [38,40].…”

If the current schedule can no longer be fulfilled, the DSS must present corresponding information (FR dod 10) [38,40]. In order to avoid continuous and active checking of the system for occurred events by the user, the system should inform the user about the occurrence of an event (FR dod 11).…”
