Discrete Event Simulation

from class:

Model-Based Systems Engineering

Definition

Discrete event simulation is a modeling technique used to represent the operation of a system as a sequence of distinct events in time. Each event occurs at a particular instant and marks a change in the state of the system, making it ideal for analyzing complex systems with dynamic interactions. This method helps in performance analysis and optimization by allowing the examination of various scenarios, predicting outcomes, and improving decision-making.
