Existing simulation techniques could help massively to evaluate these uncertainties and achieve improved and at least more robust plans during project management, but are typically not applied in industry, especially at SMEs (small and medium-sized enterprises). This paper presents some results of the joint research project simject of the Universities of Paderborn and Kassel, which aims at the development of a demonstrator for a simulation-based and logistic-integrated project planning and scheduling. Based on the researched state-of-the-art, requirements and a planning process are derived and described, as well as a draft of the current technical infrastructure of the intended modular prototype. First plug-ins for project simulation and multi-project optimization are implemented and already show possible benefits for the project management process.}}, author = {{Gutfeld, Thomas and Jessen, Ulrich and Wenzel, Sigrid and Weber, Jens}}, booktitle = {{Proceedings of the 2014 Winter Simulation Conference}}, editor = {{Tolk, Andreas and Diallo, Saikou Y. and Ryzhov, Ilya O. and Yilmaz, Levent and Buckley, Stephen J. and Miller, John A.}}, isbn = {{9781479974863}}, location = {{Savannah, GA, USA}}, pages = {{3423--3434}}, publisher = {{IEEE Press}}, title = {{{A Technical Concept for Plant Engineering by Simulation-Based and Logistic-Integrated Project Management}}}, doi = {{10.1109/WSC.2014.7020175}}, year = {{2014}}, } @inproceedings{20981, abstract = {{Real-time embedded systems (RTES), as in the automotive domain, provide their functionality by executing software operations on hardware with restricted resources and by communicating via buses. The properties of the underlying architecture, i.e., execution times of software operations and bus latencies, cause delays during the provision of the functionality. At the same time, RTES have to fulfill strict real-time requirements. The fulfillment of such real-time requirements under consideration of delays induced by architectural properties should be taken into account already during requirements engineering (RE) to avoid costly iterations in subsequent development phases. In previous work, we developed a formal RE approach based on a recent Live Sequence Chart (LSC) variant, so-called Modal Sequence Diagrams (MSDs). This scenario-based RE approach allows to validate the requirements by means of simulation, i.e., the play-out algorithm originally conceived for LSCs. Our MSD play-out approach considers assumptions on the environment as well as real-time requirements and is applicable to hierarchical component architectures, which makes it well suited for automotive systems. However, delays induced by architectural properties are not considered. In order to consider this important aspect, we introduce in this paper an approach enabling the annotation of software operation execution times and connector latencies to hierarchical component architectures by means of the MARTE profile. These assumptions about the architectural properties can be verified against the real-time requirements specified in the MSDs by means of simulation. We illustrate the approach by means of an example of an automotive RTES.}}, author = {{Holtmann, Jörg and Shipchanov, Dimitar}}, booktitle = {{Proceedings of 12th Workshop Automotive Software Engineering}}, pages = {{2169–2180}}, publisher = {{Bonner Koellen Verlag}}, title = {{{Considering Architectural Properties in Real-time Play-out}}}, volume = {{P-232}}, year = {{2014}}, } @phdthesis{21503, abstract = {{Bei der Umsetzung von innovativen Leichtbaukonzepten finden verstärkt mechanische Fügeverfahren Anwendung. Folglich werden im Automobilbau, neben den konventionellen Fügeverfahren wie dem Widerstandspunktschweißen, mechanische Verbindungstechniken, wie z.B. das Halbhohlstanznieten eingesetzt.Für den effektiven Einsatz dieser Fügetechniken insbesondere in crashrelevanten Bereichen fehlen jedoch bislang Verbindungskennwerte, die eine Vorhersage über das Tragverhalten dieser Verbindungen ermöglichen. Das Ziel dieser Arbeit war es, das Tragverhalten von Halbhohlstanznietverbindungen für den Lastfall Crash zu charakterisieren und eine Methode aufzuzeigen, mit deren Hilfe es möglich ist, das experimentell ermittelte Verhalten rechnerisch abzuschätzen. Diese Arbeit beinhaltet, neben der experimentellen Ermittlung von Werkstoffkennwerten, die Ergebnisse zur Charakterisierung der Tragfähigkeit von Halbhohlstanznietverbindungen unter Crashbelastung. Dabei wird neben der einfach überlappten Zugscher- und Schälzugprobe das patentierte LWF-KS-2-Prüfkonzept eingesetzt, welches Tragfähigkeitsuntersuchungen unter Berücksichtigung der Lasteinleitungsrichtung und der Belastungsgeschwindigkeit erlaubt. Als Versuchswerkstoffe kamen dabei der mikrolegierte Stahlwerkstoff HC340LA,der Bake-Hardening-Stahl HC180BD, der Dualphasenstahl HCT600X sowie die Aluminiumlegierungen EN AW-6014 und EN AW-6060 zum Einsatz.
