Cross Docking in the Warehouse

By

Introduction

The term cross docking refers to moving product from a manufacturing plant and delivers it directly to the customer with little or no material handling in between. Cross docking not only reduces material handling, but also reduces the need to store the products in the warehouse. In most cases the products sent from the manufacturing area to the loading dock has been allocated for outbound deliveries. In some instances the products will not arrive at the loading dock from the manufacturing area, but may arrive as a purchased product that is being re-sold or being delivered from another of the companies manufacturing plants for shipment from the warehouse.

Benefits

Many companies have benefitted from using cross docking. Some of the benefits include:

  • Reduction in labor costs, as the products no longer requires picking and putaway in the warehouse.
  • Reduction in the time from production to the customer, which helps improve customer satisfaction.
  • Reduction in the need for warehouse space, as there is no requirement to storage the products.

Types of Cross Docking

There are a number of cross docking scenarios that are available to the warehouse management. Companies will use the type of cross docking that is applicable to the type of products that they are shipping.

  • Manufacturing Cross Docking – This procedure involves the receiving of purchased and inbound products that are required by manufacturing. The warehouse may receive the products and prepare sub-assemblies for the production orders.
  • Distributor Cross Docking – This process consolidates inbound products from different vendors into a mixed product pallet, which is delivered to the customer when the final item is received. For example, computer parts distributors can source their components from various vendors and combine them into one shipment for the customer.
  • Transportation Cross Docking – This operation combines shipments from a number of different carriers in the less-than-truckload (LTL) and small package industries to gain economies of scale.
  • Retail Cross Docking – This process involves the receipt of products from multiple vendors and sorting onto outbound trucks for a number of retail stores. This method was used by Wal-Mart in the 1980's. They would procure two types of products, items they sell each day of the year, called staple stock, and large quantities products which is purchased once and sold by the stores and not usually stocked again. This second type of procurement is called direct freight and Wal-Mart minimize any warehouse costs with direct freight by using cross docking and keeping it in the warehouse for as little time as possible.
  • Opportunistic Cross Docking – This can be used in any warehouse, transferring a product directly from the goods receiving dock to the outbound shipping dock to meet a known demand, i.e. a customer sales order.

Products Suitable for Cross Docking

There are materials that are better suited to cross docking than others. The list below shows a number of types of material that are more suited to cross docking.
