Efficient order picking system in the Decathlon warehouse in Poland

Decathlon, your neighborhood sports store

Decathlon is a hypermarket chain that focuses on selling and distributing sporting goods. Established in France in 1976 and, since then, it has opened more than 1,100 shops around the world.

The company makes and markets its private label brands, specifically designed to meet the needs of sportspeople. Each brand represents a specific sport or activity, such as dancing, swimming, cycling, mountain sports, fishing, fitness or tennis.

Need: boost online sales

Decathlon is a very innovative company, which rethinks its business strategy constantly in order to increase customer satisfaction. To that effect, in the last few years, it has focused on opening new urban-based stores in downtown capital city areas.

Meanwhile, it has also boosted the online sale of products bought off its website and improved order delivery times. Solidifying these aims would require a system that could bring speed to order picking and consolidation.

The company Decathlon asked for Interlake Mecalux’s collaboration to get the maximum storage capacity in its new logistics center in Łódź (Poland). Likewise, this required that SKUs be classified based on their sizes and taking ABC rotation criteria into account.

Dividing the warehouse

The facility is sectored into three different zones:

1. Mezzanine with picking shelves
2. Reception and dispatch area
3. Selective pallet rack

Both the mezzanine floor and ground level were installed with hand-pick shelving for small-sized products. A conveyor circuit connects the two floors and automatically moves finished boxed orders up to the completion and consolidation area.

On the other hand, the pallet racks are set aside for bulky products and palletized reserves with goods for the picking shelves.

Selective pallet racks

The 31' high by 292' long pallet racks offer storage capacity for 11,518 pallets. Picking is also done directly from the pallets on lower levels, where boxes are picked right off pallets.

An underpass was enabled that cuts across the racks and improves personnel workflows, while also acting as an emergency exit. The levels above are fitted out with electro-welded mesh to prevent the accidental fall of materials.

This warehouse is operated by reach trucks to insert and extract pallets from their locations and by ground level order pickers for picking.

Order preparation

Picking shelves feature direct access to boxes, which facilitates the handling of the small-sized goods contained inside the boxes.

Picking is based on the «person-to-product» criteria: operators push handcarts up to the shelves to manually pick the SKUs listed by the warehouse management software (WMS) on a radiofrequency device.

Replenishment takes places when fewer numbers of orders are being prepped. Operators deposit pallets with reserve product on the mezzanine level using reach trucks. Two up and over pallet gates were arranged on the mezzanine to keep operators completely safe during the loading of goods.

Sorted, consolidated and shipped out

The conveyor circuit ends at the consolidation area where the finished orders are sorted automatically into eight different channels. Next, workers verify orders are error-free, they seal the boxes and distribute them on pallets, sorted by customer or shipping route.

Pallets from the same order or route are grouped together on the floor in front of the docks, streamlining the subsequent loading of trucks and avoiding timeouts.
