For systems based on hierarchical component architectures like AUTOSAR and developed in conformance with process models such as Automotive SPICE, requirements should be specified for the whole system under development and partitioned subsequently onto the particular components across several hierarchy layers. In previous work, we developed a formal requirements engineering (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) and to formally verify the requirements for consistency. However, these scenarios are specified on a plain structural basis that does not reflect the typical structure of component architectures, which are arranged in a hierarchical way and encompass ports, interfaces, and directed connectors. In order to tackle this problem, we introduce in this paper a modeling and simulation approach for MSDs based on hierarchical component architectures. By binding these two aspects together, we foster an integrated and iterative RE and component architecture design. }}, author = {{Holtmann, Jörg and Meyer, Matthias}}, booktitle = {{Proceedings of 11th Workshop Automotive Software Engineering}}, pages = {{2458–2472}}, publisher = {{Bonner Koellen Verlag}}, title = {{{Play-out for Hierarchical Component Architectures}}}, volume = {{P-220}}, year = {{2013}}, } @inproceedings{20913, author = {{Frieben, Jens and Heutger, Henning and Meyer, Matthias and Becker, Steffen}}, booktitle = {{9.

The amount of used powder, which is not sintered, can be refreshed and used for further building jobs. Due to cost reduction, better mechanical properties and a simpler processing it is reasonable to combine virgin and used powder for part manufacturing. During the building time the powder is thermally loaded and its structure is changed. State of the art in laser sintering is a defined powder ratio. Since the powder ageing depends on the individual history of sintering, this procedure cannot ensure a defined powder quality. However, for a serial production it is necessary to characterize the raw material, as well as all other steps along the process chain, in order to ensure a high reproducibility and reliability. Rheological, physical and particle properties are considered to correlate powder and chosen material properties. Different powder qualities adjusted by the Melt Volume Rate (MVR) are tested using promising rheological properties like viscosity or molecular weight. Investigations about powder bed density, bulk properties as well as thermal characterization complement the experimental setup. These parameters are correlated with mechanical, electrical, thermal and physical material properties of laser sintered parts. The most important influencing factors along the process chain are kept constant. At the end a procedure is shown to obtain a defined powder quality. This procedure will be transferred to other materials and will be tested using other laser sintering machines of the same type as well as other types.}}, author = {{Rüsenberg, Stefan and Schmid, Hans-Joachim}}, booktitle = {{International Conference of the Polymer-Processing-Society (PPS)}}, title = {{{Advanced characterization method of Nylon 12 materials for application in laser sinter processing}}}, doi = {{10.1063/1.4873877}}, volume = {{29}}, year = {{2013}}, } @inproceedings{22197, author = {{Josupeit, Stefan and Rüsenberg, Stefan and Schmid, Hans-Joachim}}, booktitle = {{Merseburger Rapid Prototyping Forum}}, title = {{{Mechanische und rheologische Untersuchungen neuer Laser Sinter Materialien}}}, doi = {{https://www.rp-netzwerk.de/images/stories/pdf/rapid_7/Universitaet_Paderborn_DMRC_RP-Forum2013.pdf}}, volume = {{7}}, year = {{2013}}, } @inproceedings{22201, author = {{Rüsenberg, Stefan and Bagsik, A. and Büsching, J. and Schmid, Hans-Joachim}}, booktitle = {{RapidTech}}, title = {{{Additiv versus Konventionell: Benchmarking am Beispiel eines Designs aus der Luftfahrtindustrie}}}, year = {{2013}}, } @inproceedings{22373, author = {{Adam, Guido and Zimmer, Detmar}}, title = {{{Design for additive manufacturing}}}, year = {{2013}}, } @article{22374, abstract = {{Additive Fertigungsverfahren stellen Bauteile und Baugruppen aus Kunststoff- oder Metallwerkstoffen schicht¬weise, ohne formgebendes Werkzeug her.

Due to the modification of the new production process and new supply chains during a parts lifecycle, producing companies can strongly benefit from AM. Therefore, a costing model for assessing lifecycle costs with regard to specific applications and branches has been developed. The costing model represents the advantages of AM monetarily. For the evaluation of this model and the influence factors, different case studies have been performed including different approaches in part redesign. Deeper research is and will be carried out with respect to the AM building rates and the comparability of various AM machines, as these facts are hardly comparable for end users.
