Simulation modeling

Definition

Simulation modeling is a technique used to create a digital representation of a real-world process or system, allowing for analysis and experimentation without the need for physical trials. This method helps in understanding complex systems by mimicking their behavior over time and under various conditions, providing insights into outcomes and potential changes. It plays a crucial role in decision-making processes across various fields, enabling more informed predictions and strategies.
