Understanding the Dual Role of Warehousing and Distribution in Supply Chains

Warehousing and distribution are essential elements in supply chains, acting as fundamental links between production and consumption, which are crucial for good customer service and cost management.

Warehouses are more than just storage spaces; they also encompass reception, storage, order preparation, shipping, cross-docking, customer service, and operational planning and control. They take a strategic position in the dynamics of product flow, inventory optimization, cost reduction, and logistics efficiency maximization.

Distribution, in turn, is the link ensuring the delivery of products to consumers or points of sale, incorporating logistics planning, pickup and delivery, load capacity optimization, and vehicle maintenance. An efficient distribution strategy ensures the right products reach the right place at the right time and conditions.

Effective integration between warehousing and distribution is essential for optimizing supply chains. Synchronizing these activities allows for a quicker response to demand changes, reduces stock excess, improves storage space utilization, and increases transportation efficiency. An excellent logistics model optimizes warehouses’ network and operation (warehouse location and stock allocation) and transportation (transportation categories and distribution strategies).

Core Principles for Effective Warehousing

Effective warehousing is essential in modern supply chains, ensuring products are kept in optimal conditions and available for distribution at the right time. This chapter addresses the Lean principles that underpin effective warehousing.

Warehouse Layout and Picking

Efficient warehouse design and optimized picking practices are essential to operational efficiency and customer satisfaction in any supply chain.

Let’s explore the principles of warehouse design:

• Organization by Value Stream: Grouping items based on product family, market/customer, similar picking methods, or similar storage specifications helps in quickly locating items and reducing order preparation time.
• Flow-Oriented Layout: Adopting a U-shaped layout with coinciding or close entry and exit areas promotes a continuous workflow and minimizes wasting time in unnecessary movements.
• Location by Consumption: Positioning products according to consumption frequency significantly reduces distances traveled during picking and storing operations, optimizing operator time.
• Packaging Units and Storage Areas Optimization: Adjusting packaging units and configuring storage areas to accommodate products efficiently can significantly improve space utilization.
• Visual Management and Standardization: Implementing visual signals and standardizing processes can help quickly identify items and consistently execute operations, reducing errors.
• Daily Operations Management: Real-time productivity, quality, and monitoring of other KPIs allows for early problem detection and swift corrective decision-making.
• Safety, Ergonomics, and Error-Proofing Systems: Designing the warehouse with a focus on safety and ergonomics minimizes the risk of accidents and injuries while error-proofing systems (poka-yoke) help prevent operational errors.

Another essential practice in a warehouse is having a good picking process, as this is a significant portion of direct warehouse labor costs. Next, we will address some of the good practices in picking:

• Separate Picking and Replenishment: Dedicating exclusive aisles for picking and replenishment reduces interference between these activities, increasing efficiency and safety.
• Dimensions Adapted to Product and Consumption: Keeping the dimensions of aisles and picking positions to a minimum reduces distances and improves productivity.
• Adjust Picking Strategies: Defining picking strategies – batch picking, multi-order, pick and pack, picking by line, picking by store, cross-docking – according to order profiles can significantly increase productivity.
• Make “A” References Accessible: Positioning the most sought-after items (“A” references) in easily accessible locations maximizes picking efficiency.
• Frequently Ordered Items Located Close to Each Other: Placing items commonly ordered together in close positions can reduce picking time.
• Eliminate Unnecessary Records and Documents: Streamlining processes by eliminating redundant documentation speeds up operations and reduces errors.
• Hands-Free Picking: Implementing solutions that allow hands-free picking, such as headsets for vocal instructions (voice picking) increases productivity.
