Wait

Entity-Related Operation Statement

Syntax samples

WAIT <time expression>

WAIT 3 min

WAIT 0

WAIT 2.5 + CleanupTime

WAIT N(8,.5) + 3 sec

Description

Simulates the time it takes to process an entity. WAIT delays further processing of the entity until the specified time has elapsed. The rest of the model continues to process while an entity waits. If the expression evaluates to zero, the current entity will not finish processing until all other processes scheduled for that moment in the simulation have finished.

Please note

You may use the "^" symbol in place of a "WAIT" statement.

Valid In

Location processing, downtime, and move logic. Independent subroutines may also use WAIT statements which function as timers. (For more information about Independent subroutines, see Subroutines.)

Components

<time expression>

The length of the WAIT. This expression is evaluated whenever the statement is encountered. If no time unit is specified, the default time unit specified in the General Information Dialog is applied.

Example

In the following example, customers arrive at a fast-food restaurant and place their orders at location Counter. How long customers wait depends on the type of meal ordered. If they order meal one, two, or three, they wait only 2 minutes. Otherwise they wait 5 minutes.The example below shows WAIT statements used in an IF...THEN...ELSE expression. If the value of EntA’s attribute, Attr1, is greater than zero, the time delay is 5.0 minutes. Otherwise the delay is 2.5 minutes.
