Understanding Warehouse Slotting Optimization
Warehouse slotting optimization is about putting items in the right spots. This makes picking easier, balances work, and speeds up how things move. It helps make order times shorter, workers more productive, and costs lower.
By using smart ways, messy aisles become smooth paths. These paths help with everyday tasks and big busy times.
Definition and Importance
Slotting means putting items in spots based on how fast they sell, size, and when they need to be restocked. It makes picking faster and uses less labor. Companies like Manhattan Associates and Blue Yonder use AI to find the best spots.
Good slotting considers how fast items sell, when they sell more, size, and how they pack. This helps managers plan better and use both people and machines well. It also changes spots as needed to meet demand.
How Slotting Affects Warehouse Efficiency
Bad slotting makes pickers walk more and causes jams near busy areas. This wears out machines, increases mistakes, and slows things down. It also costs more for energy and fixing things.
Good slotting makes picking faster, replenishment smoother, and things move better. AI helps teams try different setups and make changes without much trouble. This leads to more picks per hour and lower costs per order.
