  abstract     = {{Nowadays requirements are mostly specified in unrestricted natural language so that each stakeholder understands them. To ensure high quality and to avoid misunderstandings, the requirements have to be validated. Because of the ambiguity of natural language and the resulting absence of an automatic mechanism, this has to be done manually. Such manual validation techniques are timeconsuming, error-prone, and repetitive because hundreds or thousands of requirements must be checked. With an automatic validation the requirements engineering process can be faster and can produce requirements of higher quality. To realize an automatism, we propose a controlled natural language (CNL) for the documentation of requirements. On basis of the CNL, a concept for an automatic requirements validation is developed for the identification of inconsistencies and incomplete requirements. Additionally, automated correction operations for such defective requirements are presented. The approach improves the quality of the requirements and therefore the quality of the whole development process.}},

Dies fuehrt zu immer komplexeren Systemen, wobei auch immer mehr sicherheitskritische Funktionen durch Software realisiert werden. Damit die Qualitaet der Software entsprechend hoch und zufriedenstellend ist, erfordert die Entwicklung ein systematisches und prozesskonformes Vorgehen. Der fuer die Softwarearchitektur entwickelte AUTOSAR Standard ist allerdings nicht fuer die fruehen Entwicklungsphasen wie die Anforderungsanalyse und das Systemarchitekturdesign gedacht, welche von Prozessbewertungsmodellen – wie Automotive SPICE – gefordert werden. Als Loesung fuer die Analyse bietet sich die Nutzung der Systems Modeling Language (SysML) mit Anpassungen bzw. Erweiterungen an die Beduerfnisse der Automobilindustrie, an. Damit aber keine Luecke im Entwicklungsprozess entsteht, wird bei der hier vorgestellten Methode ein wohldefinierter uebergang zur AUTOSAR Architektur, und zwar zur Applikations- und zur Basissoftware, definiert.

  abstract     = {{Software maintenance tasks require knowledge about the software’s design. Several tools help to identify implementations of software patterns, e.g. Design Patterns, in source code and thus help to reveal the underlying design. In case of the reverse engineering tool suite Reclipse, detection algorithms are generated from manually created, formal pattern specifications. Due to numerous variants that have to be considered, the pattern specification is error-prone. Because of this, the complex, step-wise generation process has to be traceable backwards to identify specification mistakes. To increase the traceability, we directly interpret the detection algorithm models (story diagrams) instead of executing code generated from these models. This way, a reverse engineer no longer has to relate generated code to the story diagrams to find mistakes in pattern specifications.

Current and future standards and maturity models impose high accuracy and quality for the development process of such software-intensive, embedded systems. But nowadays, there are process and tooling gaps between different modeling aspects for the system under development (SUD). Furthermore, the SUD is usually verified and validated not until it is completely implemented, which leads to expensive corrections. In this paper we present a seamless, model-based development process, which is intended for the automotive supplier domain and conforms to the process reference model of Automotive SPICE. The development process addresses the issues mentioned above by using systematic transitions between different modeling aspects and simulations in early development stages.}},

  abstract     = {{Self-healing promises to improve the dependability of systems. In particular safety-critical systems like automotive systems are well suited application, since safe operation is required in these systems even in case of failures. Prerequisite for the improved dependability is the correct realization of the self-healing techniques. Consequently, self-healing activities should be rigorously specified and appropriately integrated with the rest of the system. In this paper, we present an approach for designing self-healing mechanisms in automotive systems. The approach contains a construction model which consist of a structural description as well as an extensive set of constraints. The constraints specify a correct system structure and are also used in the self-healing activities. We exemplify the self-healing approach using the adaptive cruise control system of modern cars.

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.}},
