Pepsi Bottling Group
Pepsi owns 261 distribution centers in the US. Many are part of
bottling operations, as is this one in Atlanta. This one stocks
around 400 skus. Pepsi tries to keep no more than eight days of
inventory on hand.
The DC picks cartons of beverages onto pallets and then load the
pallets directly into waiting trailers. The facility recently
converted to “pick-to-voice” and reports that training
time has been reduced. But without a pick list, experienced workers
are no longer able to plan convenient routes. They must rely on the
control system to do this.
The warehouse management system organizes the customer requests into
pallets and then directs the picker to the appropriate skus to build
this pallet.
There are about 16 order pickers working within 7 aisles. The forward
pick area is restocked in the morning after visual check. A popular
sku will have several pallets floor-stacked in the forward area and
“letdowns” are performed as needed.
There are two kinds of customer orders: warehouse transfers are
typically full pallets that are being moved from this manufacturing
site to an outlying DC; and regular orders, which are stores or other
outlets for the product.
Order-picking
Order-pickers ride through the forward pick area, picking cartons to pallets.
|
Order-picking
Pick-to-voice has reduced the learning curve, but pickers cannot plan their own routes.
|
Pick aisle
Orders for small customers flow toward the doors, orders for large customers flow in the reverse direction.
|
Cans are picked first
Cans provide a stable platform on which to stack subsequent items.
|
2-liter bottles
These are especially popular during holidays and Superbowl.
|
A properly built pallet
Cans on bottom, then 2-liter bottles, then smaller bottles.
|
53-foot trailer
These carry customer orders, especially high-volume ones, for delivery to the store.
|
Only about 50% full
There is not enough height to stack pallets, so they are loaded 1-high, 2-across, 11-deep.
|
Side-loading trailer
Customer orders are aggregated and product “picked-to-truck”. At delivery, the truck is picked like a small warehouse.
|
Honeycombing
Space at the front of a lane is unusable until the lane is empty and can be reassigned.
|
3-deep floor stack
Most product stacks well and is stored in lanes of various depths.
|
Pallet rack
Non-carbonated product is at greater risk of damage if stacked so expensive skus are put in rack.
