Modeling and simulation

Definition

Modeling and simulation refer to the process of creating abstract representations (models) of real-world systems and using those models to study their behavior through simulations. This method is essential in engineering fields, as it allows researchers to predict outcomes, test scenarios, and optimize designs without the need for physical prototypes. In the context of research directions and technology roadmaps, modeling and simulation play a crucial role in assessing future technologies and guiding development efforts by providing insights into performance and feasibility.
