    SimuLizar NG: An extensible event-oriented simulation engine for self-adaptive software architectures
    (Softwaretechnik-Trends Band 39, Heft 3, 2019) Krach, Sebastian Dieter; Scheerer, Max
    Software simulation constitutes an essential mechanism for design time architecture analysis. Domain-specific software, e.g. of cyber-physical systems, requires domain-specific extensions to the architecture models and their execution semantics. Existing simulators are cumbersome to extend, do not support self-adaptivity or do not scale well. In this paper we present concepts of SimuLizar NG, a scalable simulation engine for the SimuLizar approach. Its principal goal is to facilitate domain-specific extension and adaptations to the model interpretation semantic while at the same time ensuring reactive simulation execution in demanding scalability scenarios.

    Towards domain-specific extensibility of quality-aware software architecture meta-models
    (Softwaretechnik-Trends Band 39, Heft 4, 2019) Krach, Sebastian Dieter
    The evermore extending presence of software systems in ubiquitous application domains requires current software architecture analyses to incorporate domain-specific concepts. Current model extension approaches are too general, do not provide sufficient support for multiple roles in the development process or impose high effort on the extension developer. In this paper, we present MDSD.tools Characteristics, a framework to enhance existing architecture description languages with easy-to-use quality modeling profiles. It facilitates capturing of domain expert knowledge concerning relevant attributes of architecture entities into reusable specifications. Furthermore, it comprises a notion of contextual information with a model-based specification for information propagation to simplify the integration with existing analyses.
