modellezéstl

Modellezéstl is a term that appears in some Hungarian-language discussions to denote an integrated practice of creating and applying computational models to study real-world systems. It is not a standardized or widely recognized discipline, and there is no consensus on its exact scope or boundaries. In this article, modellezéstl is presented as a conceptual framework for end-to-end modeling work that combines theory, data, and computation to support analysis and decision making.

At its core, modellezéstl encompasses the construction of representations of complex systems, their mathematical or computational formulation, the implementation in software, and the systematic evaluation of their accuracy and usefulness. Key components include model development, calibration to data, verification and validation, and uncertainty quantification, as well as ongoing maintenance as new information becomes available.

The typical workflow involves scoping the problem, selecting appropriate modeling approaches, building and testing the model, calibrating parameters, running simulations or analyses, and deploying insights for decision makers or operators. Interdisciplinary collaboration is common, drawing on mathematics, statistics, computer science, engineering, and domain expertise.

Applications span engineering design, environmental and public health planning, economics and finance, urban planning, and supply chain analysis. Advantages include the ability to explore scenarios, compare alternatives, and reduce risk and cost before implementing changes. Limitations include data quality requirements, model risk, and the need for careful communication of assumptions. See also modeling, simulation, digital twin, systems engineering.
