    Sammanfattning : Background Warehouse efficiency has gained a lot of attention in the recent years where racking layout and slotting of the SKUs are essential. The efficiency can be measured in the total traveling distance that occur in the warehouse. Two of the most central racking layout and slotting policies are the fishbone layout and ABC class-based slotting. LÄS MER
