Overview of Logistics Processes

Written by Adrian Berger

Xentral offers you a selection of different picking methods and individual configurations for each of these methods.

Tip

You can use picking methods centrally for your company or use them in parallel based on specific channels. For example, you can pick differently for each distribution channel—B2B pallet shipping through discrete picking, B2C Shopify via multi-order picking, and Amazon/Ebay through batch picking.

Additionally, you have the option to filter during the handover of orders to logistics or create fixed pick list profiles that allow you to manage priorities, item dimensions, quantities, special items in orders, and much more. You can manually control these profiles or have them generated automatically.

Discrete Picking (Order-specific Picking)

Illustration

Description

THUMB_kommi_uebersicht_einzelkommissionierung_003.png

Discrete picking is a method in warehouse logistics where you collect items for each order separately. This process requires you to move through the warehouse individually for each order and package the items immediately after their retrieval, before starting the next order. This method minimizes errors and mix-ups and is particularly effective in handling high-value or specific products.

Features of Discrete Picking:

  • Sequential Processing: Each order is processed one after the other, with the picker collecting all items for one order before starting the next.

  • Error Minimization: Since the picker focuses on a single order, the likelihood of errors is lower than in methods where items for multiple orders are collected simultaneously.

  • Simple Execution: This method generally does not require complex technology or specialized training, as the process is straightforward and simple.

  • Flexibility: Discrete picking can be applied in almost any warehouse environment, regardless of the size or complexity of the inventory.

Advantages:

Disadvantages:

  • High accuracy: By focusing on one order at a time, the picker minimizes mix-ups and errors.

  • Simple implementation: This method does not require specialized software or complex logistical planning.

  • Ideal for specific or high-value items: Discrete picking is particularly well-suited for orders with high-value, large, or very specific products, where precise handling is crucial.

  • Time-consuming: Discrete picking can be more time-consuming than other methods like batch or cluster picking, especially in large warehouses with many small orders.

  • Less efficient with high order volume: In environments where many small orders need to be processed quickly, more efficient methods like batch picking or multi-order picking may be more advantageous.

Note

Application Area:

Overall, discrete picking is a reliable and accurate method, particularly suited for warehouse operations where order processing precision is a top priority, the warehouse has small dimensions and short distances, or the order volume is relatively low for the warehouse size.

Batch Picking

Illustration

Description

THUMB_kommi_uebersicht_sammelkommissionierung_003.png

Batch picking is an efficient warehouse logistics method in which you collect items for multiple orders simultaneously in a single pass through the warehouse. After all the items have been collected, they are sorted at a central location and assigned to specific orders before being packed. This method reduces the number of trips through the warehouse and increases the efficiency of the picking process.

  • Multiple orders are picked simultaneously by collecting items with the same storage location in a single batch process and sorting them by order later.

  • Advantage: Reduces walking distances and increases efficiency.

  • Disadvantage: Higher risk of errors when assigning items to individual orders later.

Characteristics of Batch Picking:

  • Multiple Orders Simultaneously: Instead of processing each order individually, items for multiple orders are collected in a single pass through the warehouse.

  • Increased Efficiency: By reducing the number of trips a picker has to make through the warehouse, time and energy are saved.

  • Post-Picking Sorting: After the items are collected, they are sorted by individual orders at a central location or packing station.

Advantages:

Disadvantages:

  • Time Savings: Batch picking significantly reduces walking distances in the warehouse, making it especially efficient for a large number of smaller orders.

  • Increased Productivity: More orders can be processed in less time, as repeated trips for the same items are avoided.

  • Cost Reduction: Lower operational costs due to more efficient use of the pickers' working time.

  • Complexity in Sorting: The subsequent assignment of the collected items to individual orders can be complicated and requires careful planning and organization.

  • Susceptibility to Errors: Without appropriate technological support or meticulous processes, errors can more easily occur when assigning items to the correct orders.

  • Need for Additional Equipment: For efficient sorting of items, additional equipment or specialized software solutions may be necessary.

Note

Application Area:

Batch picking is frequently used in warehouses that manage a wide variety of products and handle a large number of multi-item orders. It is particularly suited for companies looking to optimize their warehouse operations and increase efficiency without compromising accuracy.

​

Batch Picking with pick list

Batch picking is a process where you collect items for multiple orders simultaneously using a pick list. The items are then assigned to their respective orders at a central location, such as the packing station via Xentral’s shipping center. Optionally, you can perform an additional scan per item at the packing station to reduce error rates or capture serial numbers.

​

3 Two-Step Picking (with Web Pick List, with Storage Location Scanning)

Two-Step picking is a process where you first collect all items for multiple orders simultaneously using a web pick list. Each storage location is scanned to ensure the correct items are picked. In the second stage, the items are assigned to individual orders through the Xentral shipping center.

​

4 Batch Picking

In Xentral, you can create pick lists and batches, with the 'Batch Picking' app allowing you to collect items along an optimized warehouse route into a picking cart. The items are then sorted into a shelving system at the end of the picking route by scanning, with each item assigned to a specific order compartment. Completed boxes are finalized at the packing station. An optional quality scan is available.

​

Rolling Picking (Continuous Picking)

Illustration

Description

THUMB_kommi_uebersicht_rollende_kommissionierung_003.png

In rolling picking, you use a mobile cart to collect items for multiple orders simultaneously while moving through the warehouse. This process allows you to pack the items immediately after they are picked from the warehouse directly at the cart. This is often done "just-in-time," so each order is efficiently prepared in parallel to the picking and is immediately ready for shipping.

  • The picking is done in parallel with packing, meaning items are packed immediately after being picked from the warehouse. This process often happens "just-in-time" while the picker moves through the warehouse.

  • Advantage: Speeds up the entire process and requires less interim storage.

  • Disadvantage: Unsuitable for complex orders or large shipments.

Features of Rolling Picking:

  • Mobility: The picker uses a cart with multiple compartments or bins, which is rolled through the warehouse. Items for different orders are placed into each compartment.

  • Simultaneous Picking: Items for multiple orders are collected in a single pass through the warehouse, increasing efficiency.

  • Organized Sorting: The compartments in the cart allow for pre-sorted storage of items by order or other criteria, simplifying the subsequent packing phase.

Advantages:

Disadvantages:

  • Increased Efficiency: By collecting multiple orders in a single pass, the total number of warehouse trips is reduced, saving time and boosting productivity.

  • Reduced Error Rate: Pre-sorting items into the appropriate orders directly at the cart minimizes the chances of errors during the subsequent packing phase.

  • Flexibility: This method is adaptable and can be customized for various types of products and order sizes.

  • Space Requirements: The need for larger carts can lead to limitations in tight warehouse environments.

  • Initial Investment: Acquiring specialized picking carts and maintaining them may require an initial investment.

  • Limited Scalability: The method may reach its limits with very large order volumes or extremely fast throughput times.

Note

Application Area:

Rolling picking is especially suitable for medium to large warehouses that manage a wide range of products and need to handle a high number of orders efficiently. It is commonly used in sectors such as retail, e-commerce, and other industries where speed and accuracy in handling customer orders are critical.

​

5 Multi-Order Picking

Multi-order picking is a combination of single-order and batch picking, where multiple orders are picked simultaneously but are assigned to their respective orders in real time. The picking is carried out along an optimized warehouse route.

​

Order Processing from the Back Office

Single Order Processing (Customer Service Single Order)

Single orders can be handed over to logistics directly via the action menu, regardless of the picking process. This is especially useful when customer service needs to immediately transfer a B2B order to a freight carrier. The order is either manually completed or integrated into a logistics process.

​

Warehouse Removal Without Further Process

The inventory withdrawal without further process is a quick way to process orders directly from the desk. The order is completed, inventory is booked, and a delivery note as well as an invoice are automatically generated. This method is particularly suited for sample stock or shipping directly from the office, allowing you to print the documents immediately.

​

Automation and Process Steps

  • Process Automations in logistics allow for the automatic handover of orders to the logistics system at fixed times or intervals.

  • Pick List Profiles enable the establishment of different picking strategies based on product type, volume, and the requirements of various sales channels such as e-commerce, B2B, and offline retail, among others.

  • Settings in Logistics Processes allow for the automation of certain intermediate steps, such as skipping the quality scan at the packing station or automatically printing shipping labels without a direct confirmation trigger. An overview of options can be found here: [→A2 Principles of Logistics Processes: Shipping Handover, Pick and Pack Processes].

  • If you need to operate multiple packing stations side by side, you can configure different settings for printers, devices, process steps, picking processes, and the division of tasks across two separate user accounts for Pick & Pack.

​

Fulfillment Integration (3PL)

With the fulfillment integration between Xentral and your logistics partner’s warehouse system, you can automatically exchange data. This connection allows you to send orders directly to your fulfillment partner and receive important updates such as inventory levels or delivery status back into your system. This saves time and reduces errors by eliminating the need for manual data entry. Additionally, this module can be used to manage data transfers between two Xentral systems or other external systems, providing you with flexible and comprehensive control over your data flows.
