modelbasierte

Modelbasierte describes approaches that rely on models to understand, design, analyze, verify, or operate a system. In German-speaking engineering communities the term is used across software engineering, systems engineering, and control theory. The English equivalent is model-based, and the related discipline is model-based systems engineering (MBSE).

A central idea is to treat a model as the primary development artifact. Model-based approaches use models to simulate behavior, reason about requirements, verify properties, and generate other artifacts such as documentation and source code. Executable models enable early validation and iterative refinement before committing to implementation.

Common domains include automotive control systems, aerospace, robotics, and industrial automation. Tools and languages such as MATLAB/Simulink, SCADE, SysML-based modeling, and LabVIEW support model creation, simulation, and automatic code generation. Model checking and formal verification can be applied to models to detect design flaws earlier in the life cycle.

Benefits of modellbasierte methods include earlier defect detection, reduced development risk, and faster iteration cycles. They can also enable automatic generation of parts of the implementation and documentation. Challenges involve managing model complexity, ensuring fidelity between models and real systems, and achieving interoperability among diverse toolchains and teams. Standards and practices—such as SysML for modeling and ISO/IEC 42010 for architecture descriptions—help guide the adoption of model-based engineering across industries.
