Simulation tools are currently facing two significant challenges: On the one hand, common applications are often focussed on a specific domain, which leads to a high synchronisation and integration effort in the investigation of cross-domain issues. On the other hand, the transition from simulated models to operations monitoring and continuous improvement requires a high further development effort or even a completely new implementation with other technologies. This paper aims to present a novel one-size-fits-all approach based on the Business Process Model and Notation (BPMN) standard and the Process-Driven Approach (PDA) for creating and executing process models for discrete event simulation. It combines the BPMN’s potential to graphically represent any processes in arbitrary precision with those of PDA to sustainably integrate services, databases and tools via low-code. By means of two exemplary case studies, we would like to illustrate its practical implementation and potentials and challenge the scientific discourse.

Motivated by the ongoing growth in demand for microchips, high production costs and the complex interplay of human, machine, material and method (4M), suppliers strive to develop more advanced production planning and control regimes for semiconductor production. Batching decisions often dramatically influence the overall performance of wafer fabs in terms of capacity utilization, due date compliance, cycle time and variability. To optimize such processes, we present an integrated testbed for batch formation optimization. Using a simulation of multiple semiconductor work centers, we explore how to optimize work in progress (WIP) flow with a continuous real-time scheduler and previously published batch formation heuristics. The proposed solver is designed to only optimize capacity-limited operations. By considering real-world operations requirements and semiconductor process specifics such as qualification criteria and re-entrance in our model, we demonstrate how to realize significant throughput gains. We explore and demonstrate the developed digital twin through a powerful BI frontend for historical analysis and real-time shop floor monitoring.

Die Ausgestaltung von Interaktionen in sich selbst organisierenden Systemen ist bis heute eine herausfordernde Aufgabe. Die Natur bietet zahlreiche Interaktionsmuster zur Bewältigung verschiedener Probleme. Der Beitrag stellt eine Klassifikation von Entscheidungsproblemen vor. Anhand der Klassifikation gelingt die Abbildung gängiger Entscheidungsprobleme der Produktion und Logistik auf Interaktionsmuster sich selbst organisierender Systeme. Zudem werden aus den Interaktionsmustern konkrete Lösungsvorschläge zur Anwendung auf Entscheidungsprobleme für die Produktionsplanung und -steuerung abgeleitet und diskutiert.
