Generate and Destroy Entities and Messages

Specify entity generation and termination

Discrete-event simulations typically involve discrete items of interest, called entities in SimEvents^® software. You determine what an entity signifies, based on what you are modeling. Generate entities, and inspect their structures. Use Entity Generator block to specify custom entity intergeneration times. Use Entity Terminator block to terminate entities. For more information, see Entities in a SimEvents Model.
