Simulation modeling

Definition

Simulation modeling is a technique used to replicate the behavior and performance of a system over time, allowing for the analysis of complex interactions and outcomes. This method is particularly useful in understanding real-time system requirements and constraints, as it helps in evaluating how systems respond under different conditions. Additionally, it plays a significant role in task management and scheduling by enabling designers to visualize and optimize the timing and sequencing of tasks within a system.
