Warehousing involves storing products between the point of origin and consumption. Warehouses play an important role in logistics systems by providing time and place utility. The main functions of warehouses 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 design and efficient operations aim to provide timely customer service while minimizing costs. Key warehouse processes involve receiving, storage, order picking, and shipping.
