Simulation modeling

Definition

Simulation modeling is a technique used to create a digital representation of real-world processes or systems, allowing for analysis and experimentation without the risks and costs associated with physical trials. This approach enables engineers to test various scenarios and outcomes, making it especially valuable in optimizing traffic flow, assessing control strategies, and predicting congestion in transportation networks.
