The workshop "Reliability-oriented modeling and analysis of reconfigurable systems" of the working group "Security and stability" was held at the University of Paderborn on March 10th/11th. As guest speakers we were able to win Dr. Max Walter from the Technical University of Munich. The aim of the workshop was to gain a deeper insight into the reliability-oriented modeling and analysis of reconfigurable systems. Furthermore this modeling method developed by Dr. Walter were applyed to examples from the Collaborative Research Centre 614.
After Prof. Walter Sextro welcomed the workshop participants, Dr. Walter held the opening lecture. He introduced the novel modeling method for reliability evaluation of dynamic, reconfigurable systems (LARES). It was developed in the equally entitled DFG funded project at the TU Munich. The presentation was followed by an overview presentation about the Collaborative Research Centre 614 by Mrs. Mareen Vaßholz. The four following presentations presented the different reconfigurable systems of the Collaborative Research Centre from the perspective of different domains. Thus, applications of electrical engineering, control engineering, software engineering and reliability engineering have been presented. This interdisciplinary thinking and way of working is one of the strengths of the Collaborative Research Centre 614. Markus Koester explained the challenges in terms of reliability in the development of reconfigurable hardware. Afterwards Mr. Jan Henning Kessler gave an insight into the world of technical control reconfiguration using the example of the spring-tilt module of the RailCab to the audience. Support reconfiguration of flexible communication structures and their coverage were shown by Mrs. Claudia Priesterjahn. In the last lecture of the day, Mr. Christoph Sondermann-Wölke presented the actuator configuration on the example of the X-by-wire test vehicle " Chamäleon ". The time for discussion, questions and comments between the lectures was used intensively, and a common understanding about the challenges created by the reliability-oriented modeling reconfigurable systems was generated.
On the second day of the workshop the two demonstatoren of the CRC 614 the RailCab and the Chamäleon was shown. The innovative rail transport system RailCab was presented by Mr. Jan Henning Kessler and Mr. Alexander Peters. The convoy driving on the test track was shown. The different innovative modules such as the tracking module, the linear motor and the spring-tilt module were illustrated. The X-by-wire test vehicle "Chamäleon" was presented by Mr. Peter Reinold. This exceptional test vehicle has three actuators for the propulsion, steering and active suspension for each wheel module and is therefore designed with multiple redundancy. This demonstrator was used as an example in the final discussion. The modeling method LARES was exemplary applied. Emerging issues were modeled and further questions about the on it topic of reliability-oriented modeling and analysis were answer by Dr. Walter. Dr. Walter completed his answers by illustrative examples. The limits of the previously used modeling methods were shown. The workshop included valuable discussions and will not be forgotten by the participants.
We want to thank everyone involved for the successful workshop. Special thanks to Dr. Max Walter for his dedicated work and participation in the workshop.
