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.

There is not enough height to stack pallets, so they are loaded 1-high, 2-across, 11-deep.

Customer orders are aggregated and product “picked-to-truck”. At delivery, the truck is picked like a small warehouse.

Space at the front of a lane is unusable until the lane is empty and can be reassigned.

Most product stacks well and is stored in lanes of various depths.

Non-carbonated product is at greater risk of damage if stacked so expensive skus are put in rack.
