Warehousing plays an important role in logistics by storing products between the point of origin and consumption. Warehouses provide time and place utility for materials and goods. The main functions of warehousing include transportation consolidation, product mixing, docking, service, and protecting against contingencies. There are different types of warehouses like public, private, contract, and multi-client. Design considerations include warehouse space requirements. Principles of warehouse layout focus on using one-story facilities, moving goods in straight lines, efficient equipment, effective storage, and minimizing aisle space. Key warehouse processes involve receiving, put-away, storage, order picking, and shipping. Objectives are timely customer service, tracking items, and minimizing costs.
