What is logistics picking?
"Picking" is a key step in the order-picking process. In logistics, it refers to a key stage in order picking. The picker takes the items ordered from the warehouse and assembles them in one place to form the final parcel. This crucial phase requires just as rigorous optimization as the storage,packing and dispatch preparation stages, and operators usually use the picking cart to navigate the aisles.
The aim of logistics picking
The main aim of logistics picking is to bring operators closer to the packing area, so that they can quickly retrieve the items they need, thereby minimizing their travel time. Different types of picking can be implemented in a distribution center, depending on inventory, sector of activity and scale of operations. Once the order is ready, it is packed and dispatched to the end customer or retailer.
Steps in the picking process
Logistics picking is part of the order-picking process and is based on four essential stages:
- Collection of parts from the storage area (picking).
- Sorting or pooling the parts to make up the order.
- Packing or preparing parcels for shipment.
- Shipment ofparcels by carriers.
Information needed by preparers
To optimize overall productivity and quality of service, operators need to know their order-picking path precisely. They need four crucial pieces of information:
- Picking addresses for references to be prepared.
- Quantities to be sampled.
- Reference grouping zones.
- Theorder in which items are picked.
This information is supplied to pickers via paper documents (order forms and delivery notes) or on-board computer terminals.
Use the right guidance mode
The use of on-board computer terminals and/or RFID (radio frequency identification) devices enables operators to optimize picking thanks to advanced technologies:
- Pick by voice: a radio terminal with headset enables the operator to receive voice instructions hands-free, and to validate steps by speaking into a microphone.
- Pick by light or put to light: digital displays and indicator lights indicate the location of products to be selected.
- Order picking cart Equipped with weight or light checking devices, it helps to ensure that the right number of items are placed in the right place.
By following these methods and using these tools, companies can considerably improve the efficiency of their supply chain, reducing costs and increasing customer satisfaction.
The various picking methods: an exhaustive analysis
When optimizing the picking phase, it's essential to carefully select the process best suited to the nature of the activity and the specific features of the warehouse.
1- The "man to product" process
Within this process, the order picker engages in active movement to retrieve and assemble the required products . This approach encompasses several distinct methods:
Pick and Pack" picking
This method requires the order picker to retrieve the items to be included in a parcel before routing them to the packing area, then picking up the products for another order. When handling multiple orders, one option is to collect all items before distributing them in the packing area. This strategy is particularly suitable for warehouses shipping a low volume of parcels on a daily basis, although it is not distinguished by its speed.
Put to Light" picking
This method, based on the use of luminous screens installed on operators' carts, guides them in locating and depositing the goods required for an order. As the operator approaches a specific location, the screen lights up, indicating which product to select. Once the item has been picked, the screen indicates where in the warehouse it should be deposited. This technique is ideal for warehouses with large bulk inventories, and for logisticians handling a large number of orders simultaneously.
Pick by Light" picking
In this variant, also based on light signals, these are activated directly at the storage location. In this way, the operator can easily identify the picking location and the quantity of items to be retrieved. After scanning the product, the operator is guided to the deposit location. This mode of operation is particularly suited to warehouses with high order-picking rates, requiring precise monitoring of the central inventory management system.
Voice picking
Voice Picking, an integral part of order-picking automation, equips operators with headsets and microphones connected to a terminal. This device tells them where to pick up and drop off goods. Operators can interact with the terminal to confirm pick and drop operations, or report any stock errors.
2- The "product-to-man" process
This process is characterized by the automated movement of products towards the operator, thus limiting his or her movements within the warehouse. This approach relies on the integration of advanced technologies such as robots and conveyors.
For example, autonomous robots could roam the warehouse to retrieve items and bring them to a picking station where the operator collects them. These robots are programmed to optimize their routes, thus reducing the time and effort required to collect products.
Alternatively, a central conveyor can be used. Acting like an assembly line, this conveyor transports items from the storage areas to the picking stations. Operators remain at their workstations, collecting items as they arrive, enabling orders to be prepared without the need to move.
This process is particularly effective for large-scale or high-speed warehouses, where speed and precision are crucial. It promotes more efficient real-time inventory management and reduces the risk of human error. What's more, it improves operators' working conditions by minimizing their movements and physical effort.
Rolls Rapide's recommendations for optimizing picking
The picking process is an essential link in the supply chain, and optimizing it can lead to significant gains in productivity, accuracy and customer satisfaction. Here are five tips for improving this process:
- Reduce travel distances: Optimal inventory management is of paramount importance. The ABC method can be used to prioritize items representing 80% of total value with only 20% of SKUs. The FIFO ("First In - First Out") method can also be adopted to store older products close to the picking area.
- Limit load breaks and damage risks: Using a real-time tracking tool helps minimize load breaks by monitoring goods movements. It is essential to respect the nature of products by defining appropriate preparation paths and picking items according to weight and density to avoid damage.
- Optimize item accessibility: Make sure items are easily identifiable and accessible. Place heavy items high up, and create aisles where operators can pass each other unhindered. Arrange items visibly on shelves, and avoid overloading the same area with too many simultaneous preparations.
- Use the right storage units: Choosing storage units that are adapted to stock rotation, volume and density makes it easier to organize and access products quickly.
- Invest in specialized software: The acquisition of specialized software is a major asset for automating parcel preparation, dispatch and tracking. It centralizes and optimizes the entire process, improving warehouse performance and productivity.
Conclusion
Logistics picking is of vital importance in order preparation. By optimizing this phase, you can increase efficiency, reduce errors and improve customer satisfaction. Choosing the right picking methods for your business is combined with practical tips for optimal organization and stock management. It can transform your order picking and strengthen your entire supply chain. At Rolls Rapide, we firmly believe that logistics picking is the key to efficient logistics and optimum customer satisfaction.
