modellrendszert

modellrendszert is a concept describing a structured assembly of models and modelling artefacts designed to represent aspects of a real system. It includes the models themselves, meta-models that define modelling language and constraints, repositories for model storage, and the governance and tooling that enable re-use and collaboration. Typical elements include model libraries, version control, validation protocols, and interoperability interfaces to data sources and other models. In practice, modellrendszert supports activities such as modelling, simulation, analysis, calibration, and decision support. It is used in software engineering (model-driven development), systems engineering, environmental and socio-economic modelling, and urban planning.

Key design principles include modularity, hierarchy, traceability, and standardization; lifecycle stages include specification, construction, verification, calibration, validation, and deployment. The aim is to provide a coherent framework where models can be created, combined, and reused across projects while maintaining quality and consistency.

Implementation approaches vary by domain but commonly involve model repositories, meta-models, modelling languages, and governance structures that define roles, responsibilities, and workflows. Interoperability with data sources, simulation engines, and other modelling tools is often emphasized to enable integrated analysis and scenario testing.

Challenges for modellrendszert include managing complexity, ensuring cross-domain compatibility, maintaining up-to-date models, and establishing clear standards for documentation and validation. When effectively established, a modellrendszert can enhance transparency, reproducibility, and the efficiency of modelling activities across organisations and projects.
