COMBmodellen

COMBmodellen is a term used in Nordic academic literature to refer to a family of modelling approaches that aim to analyze complex systems by combining combinatorial optimization with empirical data and theoretical constraints. Although the term is used in several disciplines, the common thread is a modular framework in which individual components (data input, model logic, and output interpretation) can be adapted to different contexts.

Core features include a modular architecture that enables substitution of components, integration of multiple data sources, explicit handling of uncertainty, scenario analysis, and transparent documentation of assumptions and parameters. Methodologically, COMBmodellen typically proceeds from data collection and preprocessing, through model specification and calibration, to validation and scenario testing.

Applications span environmental planning, transport and logistics, energy systems, and policy analysis, where decision-makers must explore trade-offs under uncertainty. Because COMBmodellen is a broad label rather than a single standardized model, specific implementations vary by field and institution; users should consult domain-specific references for exact definitions, software, and validation results.
