Modellbasierten

Modellbasiert, or modellbasiert/ modellbasierte, isch a German term used to describe approaches, methods or architectures that rely primarily on formal or semi-formal models as the basis for design, analysis and decision making. The term emphasizes the central role of models in representing system behavior, structure or requirements, rather than relying solely on empirical testing or ad hoc reasoning. In usage, the attributive form angepasst to nouns (for example modellbasierten Ansätzen) changes with case and number.

In practice, modellbasierte Ansätze appear in several domains. In software and systems engineering, model-based development (MBD) and model-based design use abstract models to simulate, validate and generate artifacts such as code or documentation. In control engineering, model-based control designs use mathematical models of plants to design controllers and perform stability analysis. In testing, model-based testing derives test cases from models of expected behavior. Across these fields, models can be graphical, mathematical, or a combination, and they may be formal (such as state machines or differential equations) or semi-formal (such as UML diagrams).

The advantages of modellbasierte methods include improved abstraction, earlier verification, traceability from requirements to implementation, and opportunities for automated code generation and simulation. However, challenges exist, such as ensuring model fidelity with the real system, managing model complexity, maintaining consistency across toolchains, and handling the costs of tooling and training. Overall, modellbasierte approaches aim to increase predictability and efficiency by making assumptions explicit and testable through models.
