Modelling vs. Simulation: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on December 25, 2023
Modelling is creating a representation of a system or process, while simulation involves using a model to replicate and study behavior under various conditions.

Key Differences

Modelling involves creating abstract representations of systems, capturing essential features to study them, while simulation uses these models to run experiments and predict outcomes.

Modelling is the foundational step in analysis, focusing on the design of the model itself. In contrast, simulation is the application phase, where the model is put into action to test scenarios.
