    Modelbased Process and Systems Modelling to accelerate innovation management - Joint research project ISYPROM. The main objective of the ISYPROM project was the tighter integration between virtual product creation and enterprise/ business process modelling to support a holistic view and optimization of product development and innovation processes. In support of this objective the project focused on the implementation of more formalised, model-based and therefore computer interpretable representations of products and their corresponding product development processes with the overlaying enterprise and business processes.

    For the integration of the tasks to be mastered within the development process it is necessary to take account of non-geometrical information, from product design to manufacturing process, alongside geometrical design shape. The introduction of objects as carriers of semantic information leads to the use of features. In the present contribution, a concept and its realization are described that facilitate a flexible definition and computer-internal representation as well as the interpretation of features as semantically endowed objects. Based on the feature model, approaches are introduced for the support of product development with the partial tasks conception, design, integrated planning of manufacture and quality assurance.

The introduction of objects as carriers of semantic information leads to the use of features. In the present contribution, a concept and its realization are described that facilitate a flexible definition and computer-internal representation as well as the interpretation of features as semantically endowed objects. Based on the feature model, basic functionalitites for feature processing are introduced, which serve as a common kernel for integrated CAE-Systems.

    Zur Integration der im Produktentwicklungsprozeß zu bewältigenden Aufgaben ist es erforderlich, neben der geometrischen Bauteilgestalt nichtgeometrische Informationen vom Produktentwurf bis zur Fertigung und Prüfung zu berücksichtigen. Die Einführung von Objekten als Träger semantischer Information führt zur Verwendung von Features. Dazu wurde im ersten Teil dieses Beitrages ein Konzept und dessen Realisierung beschrieben, das die flexible Definition und rechnerinterne Abbildung sowie die Interpretation von Features als semantikbehaftete Objekte ermöglicht. Außerdem wurden Anwendungsmodule für die Teilaufgaben Entwurf, Konstruktion und Ermittlung technologischer Prozeßfolgen beschrieben. Auf der Grundlage der behandelten Basisfunktionalitäten zur Featureverarbeitung wird in diesem Beitrag auf Anwendungsmodule zur featurebasierten Unterstützung der Vorrichtungs-, NC- und Meßplanung eingegangen.
