One of the key design choices is what types of racks and storage space you want to use in
your model. FlexSim offers multiple different types of racks and storage options, that can be
used in a variety of ways. Each of the different racks provide different visualization and
interaction options with operators and transports.
The different rack type options include:
Rack The most basic and simple shelving structure. This
is just a basic Rack with shelves, with no particular loading order.
Floor Storage Storage space on the floor that utilizes
the same matrix organizational tools for racks. This type of Storage Object is used often
for large areas of pallets, or staging areas either in receiving or shipping. Any type of
organized floor storage area would best be represented with this type of "Rack."
Gravity Flow Rack A rack that operates with rollers.
Operators and Transports will load onto the back of the rack, while the pick-face of the
rack is on the front. This type of rack with visualize objects rolling to the front, or
pick-face of the rack. The nature of this Rack Type is to be a "first in first out" loading
scheme. This Type of rack also has a small animation of the items rolling to the front of
the pick-face of the rack.
Push Back Rack A rack that operates similarly to the
Gravity Flow Rack but will be loaded both to and from the pick-face of the rack. This rack
is meant to simulate the “first in last out style” of a Push Back Rack both visually and
logically. Also like the Gravity Flow Rack, the Push Back Rack has animations for the items
as they are pushed into the slots. One reason to use a Push Back Rack as opposed to a Gravity
Flow Rack, is if your rack were against a wall, and required both loading and unloading from
Drive-in Rack This rack visually represents the
framework of a rack meant to allow forklift trucks to drive into the storage area to drop
Each type of Rack has its own unique visuals. All of these components can be edited and
altered to whatever your warehouse model requires. Whenever a new Rack or Storage Object is
dragged out into the model, it creates a Storage System object in your Tools. When opening the
Storage System object's properties window, you will see a Visualization tab. It is within this tab
that all the visual elements of your racks can be edited. For more information, please see the
Visualization Tab section in the Storage System documentation.
