Example of Rearrangement

The first figure shows the warehouse before rearrangement takes place. The warehouse has an area for fast-moving items(golden zone). It is positioned along the central aisle of the warehouse to ensure that the picker can reach it easily. The area for slow-moving itemsis positioned behind this area.

The second figure shows a typical pick path before rearrangement takes place. Since some of the storage bins containing the products to be picked are situated a long way from the central aisle in the area for slow-moving items, the picker sometimes has to drive a long way down the side aisles to pick the required products.

The third figure shows how the system tries to shorten this long pick path during rearrangement by proposing that the fast-moving products are moved to the area for fast-moving items.

The fourth figure shows the pick path after rearrangement has taken place. During picking, fast-moving items are often picked. Since these are now closer to the central aisle, the pick path is shorter. Now the picker rarely has to drive down a side aisle to pick products.
