Entity Terminator

Terminate entities

• 

Libraries:
SimEvents

Description

The Entity Terminator block accepts and destroys entities. Use this block to represent the entity departure from the model.

To customize actions when entities enter, use MATLAB^® code in the Entry action field of the Event actions tab. See Events and Event Actions, for more information.

Examples

Generating and Initializing Entities

Different ways to generate and initialize entities and their attribute values.

Open Model

M/M/1 Queuing System

Model a single-queue single-server system with a single traffic source and an infinite storage capacity. In the notation, the M stands for Markovian; M/M/1 means that the system has a Poisson arrival process, an exponential service time distribution, and one server. Queuing theory provides exact theoretical results for some performance measures of an M/M/1 queuing system and this model makes it easy to compare empirical results with the corresponding theoretical results.

Ports

Input

Port_1 — Input entity

scalar | vector | matrix

Input entity port for entities entering the terminator.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | enumerated | bus | fixed point

Output

Port_a — Number of entities arrived

scalar

Number of entities that have arrived at the block.

Dependencies

To enable this port, click the Statistics tab and select the box labeled Number of entities arrived, a.

Data Types: double

Parameters

Event action — Specify the behavior of the entity in certain events

Entry

Specify the behavior of the entity in certain events. Define the behavior in the Event action parameter. The Entry action is called just after the entity entry to the block.

Programmatic Use

Block Parameter: EntryAction

Type: character vector

Values: MATLAB code

Default: ''

Number of entities arrived, a — Outputs the number of entities that have arrived at the block

off (default) | on

Number of entities that have arrived at the block.

Programmatic Use

Block Parameter: NumberEntitiesArrived

Type: character vector

Values: 'on' | 'off'

Default: 'off'
