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.}},

  abstract     = {{In early operational phases of severe weather events, a lack of
information challenges emergency management teams to gain
an overview of the situation and make informed decisions. To
support situational exploration, unmanned aerial and ground
vehicles attract increasing attention, primarily used to
document operational sites. However, they offer further
potential in early operational phases. To ensure their reliable
use for exploration, decision-makers must be aware of
opportunities and limitations under prevailing conditions. For
this, use cases for robotic simulation in emergency response
are presented, considering technical restrictions and dynamic
influences from weather impacts. The approach of integrating
rescue robot simulation into the response phase is developed
following a five-step research design. Existing use cases of
rescue robot simulation are identified in a systematic literature
analysis. The results are extended with use cases developed for
urban flooding scenarios. Subsequently, use cases are assessed
and selected for implementation in the simulation environment
Gazebo. Finally, the results are validated with end users in the
EU research project CREXDATA, which focuses on decision
support based on processing extreme data. The implemented
use cases demonstrate the potential of robotic simulation in
emergency response to accelerate action planning in decisionmaking and provide a more detailed picture, enabling betterinformed decisions. }},

  abstract     = {{Verification planning for engineering complex systems lacks a systematic procedure for creating test scenarios. Test scenarios can be generated by combining test cases, or by integrating test cases into pre-specified scenarios. Based on a systematic literature analysis a method is developed to simplify verification planning by creating new test scenarios and enriching existing ones. To assist the V&V engineer in planning test scenarios, a catalogue of combination premises is created to support the method. The method is evaluated in the development of a platform for emergency management. Evaluation proves that the method makes modelling of test scenarios more efficient.}},

The aim of this publication is to develop a holistic V&V metadata model for the consistent, transparent and machine-processable description and linking of relevant engineering artifacts. In a five-stage research approach, essential model components are derived from literature and are integrated into a holistic model. Initial applications as part of a European research project show the potential of the model for a well-founded effect chain analysis and decision-supporting V&V processes.}},

  abstract     = {{The importance of extreme weather situations is increasing due to their number and, above all, their impact on stakeholders in emergency response. They are characterized by cascading effects with global and local interdependencies. Extreme data must be included as a basis for decision-making. The impact in emergency response depends on diverse, multidisciplinary competencies required to interpret information. Scenarios are used in various forms of preparation: in exercises, but also for the design of information systems and validation. Based on literature, this article brings together different types of scenarios and related work in the field of Model-Based Systems Engineering. Using an exemplary case relating to possible pluvial urban floods, the added value resulting from a focus on the impact of innovative solutions is discussed. It is shown that the use of scenarios helps to make the desired impact assessable for decision-makers in all phases of research and development projects.}},

Typically, simulations are used to consider a variety of potential extreme weather scenarios in preparedness phases. Due to required computing power, duration and high efforts in parameterizing such tools are hardly used within response situations. Enhanced simulation models and surrogate models based on machine learning technologies carry potentials to overcome
these challenges. An approach is presented that adopts simulation for the case of flooding events. It considers all phases from demand situation in command posts through advanced parameter space exploration to advanced visualization of simulation results in Augmented Reality. Initial evaluation results are presented, complemented by conclusions on incorporated technologies. The results contribute to future adoption of simulation even in time-critical

  abstract     = {{Engineering methodologies for Cyber-Physical Systems (CPS) call for planning simulations and physical testing in early phases of product creation. Even in Model-Based Systems Engineering, there is a lack of systematic support that results in avoidable costs and iterations in the engineering process. Planning test cases and test scenarios along the product engineering process is not sufficiently integrated in terms of support especially for verification and validation engineers. Based on a systematic literature review, concepts for model-based planning of testing are developed. Characteristics of test cases and test scenarios of CPS are systematically identified. Generic templates for the creation of test cases and scenarios are derived. Based on the templates, a System Modeling Language (SysML) profile extension is developed which enables intuitive modelling of test cases and scenarios. The SysML profile is evaluated in a sample System-of-Systems in Disaster Response. It subsumes various types of sensor systems like rescue robotics, data science algorithms and visualization technologies like Augmented Reality to support decisions in extreme weather events. The templates and SysML profile significantly add value for engineers in the early and systematic planning of verification and validation.}},
