Adaptability is currently one of the most challenging research topics. The Department of Factory Planning and Factory Management of Chemnitz University of Technology developed the Experimental and Digital Factory in which building blocks for adaptable factory systems are integrated. Hence, a powerful model factory is available for research on adaptability. The focus among others is on the continuous interaction between factory planning and factory operation. This includes an extensive interchange and processing of information between the virtual and the real factory. The rapid implementation and verification of planning results in the real environment is enabled by holistic application and integration of different methods and tools of the Digital Factory. The paper explains a concept for adaptable factory systems and the interplay of planning and operation. The approaches are demonstrated on the use case of combined planning of layout and logistics with subsequent realisation.
Kurzfristige sowie ungeplante Änderungen – wie Auftragsschwankungen, Maschinenausfälle oder Krankheitstage der Mitarbeiter – beeinflussen die Produktionsplanung und -steuerung (PPS) von Industriefirmen. Trends wie Globalisierung und erhöhter Marktdruck verstärken diese Probleme. Zur Komplexitätsbewältigung bei der Entscheidungsfindung zur Fertigungssteuerung kommen in der Produktion Werkzeuge der „Digitalen Fabrik“, beispielsweise Simulationsprogramme, oder IT (Informationstechnologie)-Lösungen, wie Manufacturing Execution Systems (MES), zum Einsatz. Eine Verknüpfung dieser Bereiche würde einen echtzeitfähigen Datenaustausch erlauben, der wiederum eine echtzeitfähige Entscheidungsunterstützung bietet. Der Fachbeitrag stellt hierfür einen Lösungsansatz vor.
Sudden and unsystematic changes, such as fluctuations in order flow, machine failures, or employee sick days affect the Production Planning and Control (PPC) activities of industrial companies. Trends like globalization and increased market pressure intensify these problems. To master the complexity of decision-making in production control, tools of the digital factory (e.g. simulation systems) or IT systems (e.g. Manufacturing Execution Systems (MES)) are applied in manufacturing. Combining these areas would enable real-time capable data exchange which, in turn, provides real-time capable decision support. This article presents an approach for solving this problem.
Die Fabrikplanung nutzt zur Darstellung des Planungsgegenstandes reale und digitale Modelle. Deren Verwendung lässt sich historischen Entwicklungsstufen zuordnen. Dem bis dato bestehenden Mangel an synergetischer Nutzung beider Modellwelten kann durch das Konzept der „Hybriden Planung“ begegnet werden. Beschrieben werden das methodische Rahmenkonzept und die beiden Ausprägungen „Schaltmix“ und „Permanentmix“ sowie Anwendungsgebiete, technische Lösungen und tangierende Konzepte.
Factory planning uses real and digital models to represent the planning object. Their use can be assigned to historical development stages. The lack of synergetic use of both model worlds, still existing today, can be remedied by the presented ‚Hybrid Planning‘ approach. The methodical framework and the two subtypes „Schaltmix“ and „Permanentmix“ are described as well as application areas, technical solutions and related approaches.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
