Servers in SimEvents Models

4-5

• A person (such as a bank teller) who performs a transaction with each arriving

customer

• A transmitter that processes and sends messages

• A machine that assembles parts in a factory

• A computer that executes programs

You might use an infinite-capacity server to represent a delaying mechanism. An

example of this is in the subsystem in “Build a Hybrid Model” on page 2-29.

Servers Inserted for Modeling Purposes

In some cases, a server in a model does not arise in an obvious way from the real-world

system but instead is included for modeling purposes. A common modeling technique

involves a delay of duration zero, that is, an infinite server whose service time is zero,

either to break an algebraic loop or to provide a place for an entity to reside while a

preceding block updates its output signals. For details and examples, see “Interleaving

of Block Operations” and “Loops in Entity Paths Without Sufficient Storage Capacity”

online.

Access Server Blocks

Server blocks reside in the Servers library of the SimEvents library set. This chapter

focuses on the Single Server block.
