SimEvents® software provides a discrete-event simulation engine that manages and processes sequences of asynchronous events. Entities are abstractions of discrete items of interest. Generating, moving, and processing entities in the system causes events, such as the arrival of a packet or the departure of an airplane. In turn, these events modify the states in the system to affect system behavior.
Characterize your entity with attributes, such as a destination address, processing time, or server delay. Use SimEvents blocks to generate, queue, service, delay, and, route entities.
