    Many of the current manufacturing systems are still implemented as sequential inflexible production lines. This creates difficulties to fulfil the customer request for customized products. The production of customized products is accompanied by major changes in the production infrastructure. To support more flexible production, the sequential production lines nowadays start to change to workshop production. In that case all production systems will be grouped by their tasks, e.g. all drilling machines are located in the same place. A manufacturing system stands for the different involved hardware and software components at the manufacturing process. Each manufacturing system is connected with the help of the shop-floor IT. The term shop-floor indicates the productive area of a factory and includes the operative work. Shop-floor IT includes the information processes and IT solutions that control, secure and record product activities. Therefore the shop-floor IT supports d irectly the execution on field level. The model based view of a production process simplifies the understanding of the product lifecycle and planning. To optimize and speed up building and changing of product processes, the modular shop-floor IT has been developed by technologies derived from cyber physical systems and internet of things. However, interoperability issues such as different implementation of controls and process variations are a major challenge.

    Manufacturing companies today often consider digital transformation more as a challenge than an opportunity. Specific solutions for individual projects are often available. The diversity of engineering disciplines in an enterprise structure ultimately make it difficult for companies to derive and sustainably implement an integrated digitisation strategy. This is mainly driven to the fact that the existing approaches and concepts for developing digitisation strategies are exceedingly technology oriented and at the same time too complex for their application. In order to be able to derive an integrated transformation roadmap on the strategic level, evaluation methods are required that allow a quick and simple classification. The initial state for pointing out the chances of change within the scope of digitisation has to be addressed as well as the target state. This contribution will explore the capabilities of an assessment concept that supports an efficient and integrated handling of the core elements for a prosperous digitisation strategy.

    Sustainability in model-based planning and control of global value creation networks

    Manufacturing companies are affected by an increasing complexity driven thru fast changing requirements in the global market. To meet the large catalogue of requirements, enterprises are forming global value creation networks and provide services jointly. The existing time pressure and the involvement of many stakeholders results in a demand of methods and tools for a quick configuration of such networks. Beside the management of material, information and money flows the quest of a sustainable corporate development poses a further challenge for the decision makers. The consideration of sustainability in business process management is one approach to take also social, economic and environmental aspects within global value creation networks into account. Reviewing existing modelling techniques shows that the requirements for a fast configuration and an adequate management of sustainability are just insufficiently addressed or are raising the complexity further. This paper will explore capabilities of an enterprise modelling technique which supports an integrated handling of network configuration and sustainability management in a fast and efficient manner.

    Vor immer mehr Fertigungsunternehmen steht die Aufgabe, in Losgröße 1 zu produzieren und dafür zahlreiche interne Prozesse entsprechend spezieller Kundenforderungen zu gestalten. Um dabei die Wirtschaftlichkeit zu sichern, brauchen die Unternehmen flexible Produktionsanlagen sowie ein flexibles Prozessnetz, die sich an die Herstellung immer neuer Produkte oder Produktvarianten anpassen lassen. Das Fraunhofer-Institut für Produktionsanlagen und Konstruktionstechnik IPK (Berlin) hat mit seinem Industry Cockpit ein Lösungspaket entwickelt, das Industrieunternehmen hilft, die komplexen Abläufe in der Fertigung schnell zu überblicken und individuell an Aufträge anzupassen. Das Industry Cockpit entstand in Kooperation mit Pickert & Partner (Karlsruhe), einem Hersteller von Software für Qualitätsmanagement (CAQ), Produktionsmanagement (MES) und Traceability (Rückverfolgbarkeit). Es kombiniert Prozessmanagement und MES zu einer dynamischen, ganzheitlichen und kontextsensitiven Monitoring-Umgebung. So liefert es jederzeit eine exakte Übersicht über die Gesamtsituation des Betriebes und sichert die zuverlässige und flexible Steuerung einer intelligenten, vernetzten Produktion. Grundlage des Systems ist die Verknüpfung von Menschen, Produkten, Maschinen, Informationssystemen und Betriebsorganisation auf Basis eines Unternehmensmodells. Wird ein flexibel gesteuertes Prozessnetzwerk mit einem anpassungsfähigen Maschinenpark kombiniert, wird im Unternehmen die Erfüllung von Kundenwünschen bis hin zum zertifizierten Unikat möglich. Da Werkzeugmaschinen sich jedoch oftmals als zu unflexibel erweisen, treibt das IPK die Qualifizierung von Bearbeitungsrobotern voran. Hier geht es vor allem um die Sicherung der notwendigen Fertigungsgenauigkeit.
