P ROMPTS
Hold module
D ESCRIPTION
This module will hold an entity in a queue to wait for a signal, wait for a specified condi-
tion to become true (scan), or be held infinitely (to be removed later with the Remove
module).
If the entity is holding for a signal, the Signal module is used elsewhere in the model to
allow the entity to move on to the next module. If the entity is holding for a given condi-
tion to be true, the entity will remain at the module (either in a defined or internal queue)
until the condition(s) becomes true. When the entity is in an infinite hold, the Remove
module is used elsewhere in the model to allow the entity to continue processing.
