Cross-Docking: Delving into This Optimisation Technique

Have you ever heard of cross-docking? This innovative logistics technique is transforming the way companies manage their supply chains. Developed to meet the need for speed and omnichannel capabilities, cross-docking offers significant advantages, such as reducing storage costs, improving delivery speed, and optimising goods flow.

But how does this technique differ from traditional delivery? How does it work, and who is it for? Dive into the fascinating world of cross-docking and discover how this strategy can revolutionise your logistics!

What is Cross-Docking?

Cross-docking is a logistics technique that facilitates the direct delivery of products from the manufacturer to the retailer or consumer, without the need for storage or intermediation. To implement it, a company requires a suitable platform for receiving goods. Also known as “direct flow delivery,” this approach suits various scenarios, whether dealing with raw materials, finished products, or components for factories, physical stores, or end consumers.

Products are handled at the receiving dock of a cross-docking terminal. They are unloaded from the delivery truck, inspected, and sorted before being reloaded into other trucks at the outbound side of the terminal. This vehicle transfer during the journey requires impeccable management of goods flow. While it may seem complex, it offers the advantage of faster product delivery.

With this strategy, items spend very little time in the warehouse after arrival. Since they are not shelved, order preparation is unnecessary. Hence, “cross the docks” means to “traverse the docks” and gives cross-docking its name.

How Does Cross-Docking Work?

In traditional supply chain management, the warehouse is the central link between suppliers (supply) and consumers (demand). The flow is discontinuous because supply and demand are not synchronised. The logistics warehouse acts as the connection point and stores goods until demand arises.

However, advancements in information systems and logistics software have led to more flexible and integrated supply management. It is within this context that cross-docking emerged. For it to succeed, optimal coordination between all involved parties (suppliers, warehouse managers, carriers, and end customers) is essential.

Generally, the process involves several stages:

1. Planning the distribution of orders placed with suppliers.
2. Receiving the parcels.
3. Recording and inspecting the received goods as part of quality control.
4. Repackaging, consolidating orders (if necessary), and shipping the products.

What is the Difference Between Cross-Docking and Traditional Delivery?

The major difference between traditional delivery and cross-docking lies in the avoidance of goods storage in the latter. Another distinction is the redistribution of products from the cross-dock platform, enabling near-instantaneous delivery of goods.

Example:

Imagine Store A orders 10 sofas, and Store B orders 15 from the same manufacturer. The transport truck arrives at the transshipment station with a total of 25 sofas. The transshipment terminal sorts the items: two trucks are designated for the different stores, waiting at the receiving end of the terminal. One truck will head to Store A with 10 sofas and the other to Store B with 15 sofas.

Types of Cross-Docking

There are various ways to organise cross-docking, with three main categories:

1. Direct Cross-Docking: Also known as pre-distributed cross-docking, this is the simplest form to implement. The supplier already prepares and arranges the load units according to final demand. The cross-docking operation is limited to receiving and dispatching the goods.
2. Indirect or Consolidated Cross-Docking: In the consolidated cross-docking model, goods are handled to meet the final customer's needs. The received load units are moved to a dedicated cross-docking or packaging area, where they are inspected and adjusted according to demand. This method involves reorganising pallets into smaller load units or, conversely, breaking down goods into individual parcels or product kits.
3. Mixed or Hybrid Cross-Docking: This more complex variant involves preparing orders in the packaging area using:
   • A portion of the goods delivered by the trucks, andA portion of those already stored in the warehouse.
   In this case, received goods may be transferred to a temporary storage area rather than going directly to cross-docking. This type offers more flexibility, allowing for a greater variety of situations but also requires effective coordination of all logistics flows.

Why Use Cross-Docking?

Cross-docking is not a novelty; many companies already employ it to meet the demands of an omnichannel logistics strategy. Here are some reasons why companies adopt this method:

1. Consolidation of Goods and Savings: This logistics strategy allows various goods to be gathered into a single mode of transport, saving time and money. For example, a hypermarket client can source beverages or fresh products from multiple suppliers. By opting for this method, items from different suppliers are centralised, simplifying transport and speeding up receipt.
2. Centralisation and Efficient Delivery: This logistics technique favours a distribution centre where products can be sorted and grouped for easier and faster dispatch to various destinations. It also allows suppliers to serve multiple clients simultaneously with the same load. As previously noted, cross-docking facilitates the shipment of an order from different suppliers to a single end recipient.
3. Breaking Down Large Parcels and Assembly: It is the ideal method for breaking down bulky products into smaller pieces, facilitating their delivery to the consumer. If the goods require assembly and the parts come from different suppliers, this method becomes particularly relevant.

Implementing a Cross-Docking Strategy

Implementing a cross-docking strategy requires updating your production chain organisation. Focus on reducing stock at every stage. Here's how your flows should be structured:

1. Receive incoming goods at the unloading dock.
2. Move them to a central area between this dock and the loading platform (outbound flow).
3. Sort incoming orders to distinguish those for cross-docking from those for storage. Ensure good control and synchronisation of upstream supplies for effective sorting.
4. Load cross-docking products into trucks that need to depart the same day or the next day.
5. Direct other goods to the warehouse for stock integration.

Different practices within the cross-docking strategy include:

• Creating palettes designed for a single client, called allotment, which may include one or more product references.
• Cross-docking with countermarking, where some companies gather products for several clients on a single pallet.
• “Neutral product pallets,” where marking and allotment are done not at the manufacturer but directly at the cross-docking platform.

Is Cross-Docking Right for You?

Perishable Products

Cross-docking is useful for companies handling products with expiration dates or susceptible to obsolescence, such as food items with a shelf life. This strategy helps reduce costs associated with refrigerated storage.

Large Parcels with High Turnover

If your business deals with large parcels with high turnover, like home appliances or furniture, this method is effective. It ensures rapid delivery, meeting customer expectations.

Order Peaks

If your business experiences order peaks, such as during sales, this method is effective. This process is increasingly used in large-scale distribution, particularly in discount stores and retail.

High Volume of Goods and Stable Demand

Finally, this method is ideal for businesses managing high volumes of goods with stable customer demand. In this context, cross-docking allows efficient planning of logistics flows without needing significant product storage to ensure security.

In conclusion, cross-docking is an innovative logistics method that optimises goods flow management and reduces storage costs. However, other tactics exist to optimise your logistics warehouse.
