Split module
D ESCRIPTION
The Split module splits a single incoming product stream into two or more outgoing
streams. Percentages are used to determine the outbound flow proportions. Outbound
product names may also be assigned.
R EMARKS
The sum of all the specified percentages must equal 100% or a run-time error will result.
A Fixed Split will always divide the product with the exact percentages you have
specified. It will not maximize flow, but rather, will reduce the output of all branches as
necessary to maintain the specified percentages. For example, assume you have two
incoming conveyors with maximum flows of 100 and 200, and an outbound conveyor
with maximum flow of 300. If you specify a 40%/60% fixed split, then the output of the
second conveyor would be limited to ((60/40) * 100) = 150. If any outbound conveyor
cannot accept product (perhaps due to accumulation or equipment failure), then all output
from the Split will be turned off.
An Adjustable Split will automatically adjust the output of each branch to maximize flow.
It will account for any constraints while attempting to achieve the designated percentages.
For example, if you have three conveyors each designated at 33.33% and one conveyor is
stopped, then the other two conveyors will each get 50% of the flow. A special case of the
Adjustable Split is available if you specify 100% for one line and 0% for every other
output. This is useful for modeling primary and secondary flow (such as a surge table or
backup line) where the secondary line is only used when the primary line is unable to take
the full Split output.
Storage module
D ESCRIPTION
The Storage module allows you to specify the parameters of a storage area as well as
animation and statistics. The Storage module is used in conjunction with the Palletizer
module. If a Storage module is not placed, then the default storage area has infinite
capacity and no animation.
R EMARKS
In many cases, the storage is not a significant part of the model. If an infinite capacity
storage with no statistics or animation is acceptable, then no Storage module is necessary.
One way to keep a depalletizer’s storage replenished is to create an entity every time it
becomes empty, then make a connection from the Storage is Empty connection point to
