Topic 2) Picking Systems

Picking Systems refer to the process of selecting and retrieving items from storage locations in a warehouse or distribution center to fulfill customer orders. It is a crucial part of order fulfillment in the supply chain, as it involves gathering the right products in the right quantities to be shipped to customers or retail stores. The efficiency and accuracy of picking systems significantly impact overall warehouse productivity and customer satisfaction.

There are different types of picking systems, each suited to different warehouse layouts, inventory types, and order volumes. Some common types of picking systems include:

Piece Picking: In this method, individual items or pieces are picked one at a time from their storage locations to fulfill orders. Piece picking is commonly used in e-commerce and retail warehouses where orders consist of a mix of various products.
Batch Picking: Batch picking involves picking multiple orders simultaneously. A picker will collect items for multiple orders during a single trip through the warehouse, increasing picking efficiency and reducing travel time.
Zone Picking: In zone picking, the warehouse is divided into specific zones, and each picker is assigned to a particular zone. Pickers are responsible for fulfilling orders within their designated zone only, streamlining the picking process.
Wave Picking: Wave picking is a combination of batch picking and zone picking. Orders are grouped into waves, and each wave is assigned to specific zones and pickers. Once all the waves are completed, they are combined to form complete orders.
Cluster Picking: Cluster picking is similar to wave picking, but pickers are responsible for picking items for multiple orders simultaneously within their assigned zones.
Pick-to-Light: In pick-to-light systems, LED lights are used to guide pickers to the correct locations in the warehouse. The lights indicate which items to pick and the quantity required.
Pick-to-Voice: Pick-to-voice systems use voice commands to guide pickers through the picking process. A voice-controlled system directs pickers to the correct locations and confirms the items to be picked.
Case Picking: Case Picking is a picking system where entire cases or cartons of products are picked from storage locations to fulfill orders. It is commonly used for products that are typically shipped in larger quantities, such as packaged goods or consumer products. In Case Picking, the picker retrieves complete cases, which may contain multiple units of the same item, and these cases are then prepared for shipment directly to customers or retail stores. Case picking is efficient for high-volume orders of a single product.
Layer Picking: Layer Picking is a picking system where entire layers of products are picked from pallets or racking systems to fulfill orders. Layers typically consist of multiple identical products stacked on a pallet or within a storage unit. In Layer Picking, the picker retrieves an entire layer of the required products, which can include multiple units of the same item. This method is efficient for orders that require larger quantities of specific products. Layer Picking is often used in distribution centers and warehouses that handle bulk orders or high-quantity shipments.
Voice Picking: Voice Picking is a picking system that uses voice-guided technology to direct warehouse pickers during the order fulfillment process. In Voice Picking, pickers wear headsets connected to a voice-controlled system. The system communicates picking instructions to the picker, guiding them to the correct storage locations and specifying the quantity of items to be picked. The picker then confirms the successful pick through voice commands, and the system updates inventory records in real-time. Voice Picking offers hands-free and eyes-free operation, increasing picking accuracy and productivity while reducing errors. Voice Picking is particularly beneficial in environments where pickers need to keep their hands free, such as in cold storage facilities or when picking small or fragile items. It is also an effective method for reducing training time for new pickers, as the voice-guided instructions are easy to follow.

The choice of picking system depends on factors such as order volume, the variety of products, warehouse layout, and required picking accuracy. Selecting the right picking system is essential for optimizing order fulfillment efficiency and reducing errors, ultimately leading to improved customer satisfaction and reduced operational costs.
