Single Order Picking
Also known as discrete order picking, single order picking is one of the most common picking methods. It consists of a single picker going into the warehouse to fulfill one order at a time. It is a straightforward, simple system that allows for a great deal of flexibility in order fulfillment. Other benefits include:
- Rapid response times
- Optimization for paper-based picking
- Improved accuracy
Similar to single order picking, batch picking sends a single picker into the warehouse, this time to retrieve multiple orders. Batch picking can be completed either manually or automatically and is well-suited for situations when multiple orders have the same SKU.
A reduction in travel times per item makes this method particularly efficient. Picking speed and accuracy is further increased when warehouse managers choose to sort inventory by popularity, thus streamlining the batch picking process.
Zone picking assigns multiple pickers their own zone of the warehouse. When an order comes in, it is received and fulfilled by the picker in the relevant zone. This method is especially advantageous in situations involving orders with multiple components. Zone picking simplifies and organizes these orders to improve overall accuracy.
Advanced Systems Picking
In advanced systems picking, workers collect order components in bulk as they travel through various zones. They will then deliver these components to a central consolidation area, where pickers use predetermined systems to rapidly separate the bulk products into individual orders.
