Simulation models

Definition

Simulation models are computational tools that replicate real-world processes or systems, allowing users to analyze their behavior under different scenarios. These models are crucial for decision-making as they enable users to explore various outcomes without the risks and costs associated with real-life experimentation. By simulating different conditions, these models can provide valuable insights into complex systems and help in evaluating the impact of changes or decisions.
