The growing usage of self-adaptive techniques leads to sophisticated reconfigurations of the software component structures during runtime. Current modeling approaches for component-based software systems do not include a transformation language for the specification of component structure reconfigurations. In this paper we therefore introduce an extension of a component-based modeling approach. This extension enables (1) the specification of hierarchical component structures and (2) the specification of structural transformations based on the specified hierarchical component structures. Further, as we consider mechatronic systems, we also show the predictable runtime behavior of the transformations.}}, author = {{Tichy, Matthias and Henkler, Stefan and Holtmann, Jörg and Oberthür, Simon}}, booktitle = {{Proceedings of the 4th Workshop on Object-oriented Modeling of Embedded Real-Time Systems (OMER 4), Paderborn, Germany}}, pages = {{27--38}}, publisher = {{Heinz Nixdorf Institut}}, title = {{{Component Story Diagrams: A Transformation Language for Component Structures in Mechatronic Systems}}}, volume = {{236}}, year = {{2008}}, } @misc{20968, author = {{Holtmann, Jörg}}, publisher = {{Software Engineering Group, University of Paderborn}}, title = {{{Graphtransformationen für komponentenbasierte Softwarearchitekturen}}}, year = {{2008}}, } @inproceedings{17416, abstract = {{In this paper we present a system for the simultaneous visualization of several parallel executed simulation replications. By aggregating the scenes of multiple similar simulations into one single scene it is possible to make a visual statistical analysis of a set of discrete event simulations as well as to easily compare different system parameterizations. The aim of our system is to enhance the model analysis, verification and validation process in terms of speed and ease. The parallel execution of several simulations of complex models and the visualization of these cannot be done on one computer, thus a parallel approach is necessary. Our system uses a thin-client and multiple processors on a PC-cluster. The rendering and the simulation execution are done on processors of the cluster. The client is used only for the visualization of the images transmitted by the cluster and for user interaction. }}, author = {{Suess, Tim and Huber, Daniel and Fischer, Matthias and Laroque, Christoph and Dangelmaier, Wilhelm}}, booktitle = {{IEEE International Symposium on Parallel and Distributed Processing with Applications}}, isbn = {{9780769534718}}, title = {{{A System for Aggregated Visualization of Multiple Parallel Discrete Event Simulations}}}, doi = {{10.1109/ispa.2008.30}}, year = {{2008}}, }
