5 Designing Paths for Entities

5-6

The topics listed below illustrate the use of the Output Switch block.

Topic Features of Example

“Select the First Available Server” on page

5-6

First port that is not blocked

switching criterion

“Use an Attribute to Select an Output Port”

on page 5-8

Attribute-based switching, where the

attribute value is random

“Model a Packet Switch” on page 5-16 Attribute-based switching in conjunction

with a Path Combiner block

“Queue Selection Using a Switch” online Switching according to a computation that

occurs upon entity arrivals

To learn about design considerations when you switch according to an input signal, see

“Use Signals To Route Entities” in the SimEvents user guide documentation. To learn

about all supported switching criteria, see the online reference page for the Output

Switch block.

Select the First Available Server

In this example, entities arriving at the Output Switch block depart through the first

entity output port that is not blocked, as long as at least one entity output port is not

blocked. An everyday example of this approach is a single queue of people waiting for

service by one of several bank tellers, cashiers, call center representatives, etc. Each

person in the queue wants to advance as soon as possible to the first available service

provider without preferring one over another.

You can implement this approach by setting the Switching criterion parameter in the

Output Switch block to First port that is not blocked.
