Queuing For Output

When an entity finishes its operation at a location, other entities to finish ahead of it may not have departed. A decision must be made to allow the entity to leave or to wait according to some queuing rule. If one of the following queuing rules is not specified, "No Queuing" will be used.

No Queuing Entities that have completed their operations at the current location are free to route to other locations independent of other entities that have finished their operations. If this option is selected it is not displayed in the Rules Box.

First In, First Out (FIFO) The first entity completing operation must leave for its next location before the second entity completing its operation can leave, and so on.

Last In, First Out (LIFO) Entities that have finished operations queue for output LIFO so the last one finished is the first to leave.

By Type Entities that have finished operations queue for output FIFO by entity type so the routing for each entity type is processed independently of routings for all other types.

Highest Attribute Value Entities that have completed operations queue for output according to the highest value of a specified attribute.

Lowest Attribute Value Entities that have completed operations queue for output according to the lowest value of a specified attribute.
