Diese Simulationslösungen, die auf der Materialphysik basieren, erzielten 1985 eine Weltpremiere: Zum ersten Mal wurde ein virtueller Crash-Test für Volkswagen durchgeführt, der den Weg für den umfangreichen Einsatz virtueller Lösungen in Entwicklungsprozessen eb- nete und neue Sicherheitsstandards etablierte. Ein neues Paradigma, die Outcome Economy Die zunehmende Komplexität stellt alle Branchen vor Herausforderungen. Die Herstel- ler stehen vor vielen neuen Aufgaben, um die Bedürfnisse der Kunden in Hinblick auf Qualität, Zuverlässigkeit, Sicherheit und pünktlicher Lieferung zu erfüllen. Die Outcome Economy erschwert die Erfüllung der wichtigen Leistungsindikatoren, da der Erfolg an der Leistung und nicht am Produkt selbst gemessen wird. Die Industrien müssen Wach- stum erzielen bei gleichzeitiger Aufrechterhaltung der Innovation. Daher entschei- den sie sich für eine digitale Transformation, die sie zu Initiativen ohne nachgewiesene Ergebnisse führen könnte.

    Optimus Rev. 2018.1 introduces new modeling methods boosted by Machine Learning. PRESS RELEASE Leuven (Belgium), November 5 - 2018 – Noesis Solutions, the developer of Optimus and id8, announces the release of Optimus Rev. 2018.1. This release introduces new modeling methods boosted by MaChine Learning, enabling engineering teams to Create aCCurate models for low and high-dimensional optimization problems faster. Many of the new updates that come with Optimus Rev. 2018.1 further enhance Design Space Exploration and Optimization Capabilities while increasing Compatibility with leading CAD/CAE solutions. This new release confirms Optimus as the industry’s preferred platform for Design Space Exploration and Engineering Optimization. Powerful modeling boosted by MaChine Learning. This new Optimus release introduces new modeling methods boosted by Machine Learning, enabling engineering teams to create accurate models for low and high-dimensional optimization problems even with a limited number of training data sets. The new Light Weight Neural Networks (LWNN), Random Forest Regression (RFR) and Relevance Vector Regression (RVR) algorithms assist the user in accurately modeling large data sets quickly. The new Best Model algorithm even assists non-expert users by automatically selecting the best-performing model for any given data set among the models available in Optimus. Enhanced Design Space Exploration and Optimization Capabilities In addition, Optimus Rev. 2018.1 brings several improvements to Optimus’ unique Adaptive DOE algorithm that learns from available data points and iteratively adds extra data samples in design space regions that matter most. This new Optimus release further extends the capabilities of NAVIRUN, the Noesis Advanced adviser, which now also supports discrete optimization problems.

Models that practical for use in industry. ▪ Collaboration: This work uses software developed by Divergent Solutions LLC, and will use SMT MASTA for verification purposes, along with other software.

Auch in stressigen Zeiten stand er mir immer mit Rat zur Seite. In diesem Rahmen möchte ich mich bei Prof. Felix Breitenecker bedanken, der die interfakultäre Zusammenarbeit in einer freundlichen Atmosphäre ermöglicht hat. Mein größter Dank gebührt Dipl.-Ing. Bernhard Heinzl für die unzähligen Stunden an Unterstützung im Laufe der Diplomarbeit. Sowohl in inhaltlicher als auch organisa- torischer Hinsicht konnten mit seiner Hilfe sämtliche Probleme aus dem Weg geräumt werden. Ich danke Dipl.-Ing. Nikolas Popper für die Untersützung der dwh GmbH, ohne deren Know-How und Infrastruktur die Arbeit nicht möglich gewesen wäre. Ein besonderes Dankeschön geht an meine Freundin Cornelia Spreitzer, die auch in schwierigen Zeiten immer für mich da war und an mich geglaubt hat. Zu guter Letzt möchte ich mich herzlich bei meinen Eltern bedanken. Ohne sie wäre mein Studium nicht möglich gewesen. Sie haben mich in meinen Entscheidungen immer unterstützt und mir so die Möglichkeit gegeben, meinen eigenen Weg zu finden. i Kurzfassung Die Vernetzung von verschiedenen Stationen der virtuellen Produktentwicklung eröff- net neue Wege für Innovation und Effizienz.
