Order picking is one of the most important activities in warehouses because of its direct effects on customerservice level and warehouse costs !
More than 60% of all operating costs of warehouses are related to order picking
- In discreet picking, a single order is filled.
- In batch picking, a group of orders are filled by one order picker.
- In zone picking, each order picker is in charge of a specific zone of the warehouse and selects items that are in that zone. All order pickers do their work until the order is completed.
- In wave picking, orders may be released in waves (e.g., hourly or each morning or afternoon).
- This helps to control the flow of goods and replenishment, picking, packing, marshalling, and dispatching. Wave timing is tied to the schedules of outgoing vehicles.
