  text: Verification and Validation (V&V) are essential processes in engineering Cyber-Physical
    Systems. However, the role of V&V engineers is often not given sufficient attention.
    Based on a systematic literature analysis and practical observations, a four-step
    method for Test-oriented Resilient Requirements Engineering (ToRRE) is developed.
    The steps are planning V&V, executing V&V activities, documenting V&V activities
    and analyzing results of V&V activities. Applying ToRRE ensures continuous information
    flow and traceability. Engineers are enabled to analyze requirements using engineering
    artifacts connected through Model-Based Systems Engineering. Adopting methods
    for Model-Based Effect Chain analysis to evaluated test cases and test scenarios,
    conclusions on requirements engineering and change management are enabled. The
    method is evaluated in an EU research project.

  text: The integrated modeling of behavior and reliability in system development
    delivers a model-based approach for reliability investigation by taking into account
    the dynamic system behavior as well as the system architecture at different phases
    of the development process. This approach features an automated synthesis of a
    reliability model out of a behavior model enabling for the closed loop modeling
    of degradation of the system and its (dynamic) behavior. The approach is integrated
    into the development process following Systems Engineering. It is based on standard
    models used in model-based development methodologies i.e. SysML or Matlab/Simulink.
    In addition to the theoretical description of the necessary steps the procedure
    is validated by an application example at two stages of the development process.
