This document presents a case study on Walmart's supply chain management. It discusses Walmart's distribution and logistics system, including its use of over 40 distribution centers across the US and supplying 85% of inventory directly from these centers. It also discusses how information technology benefited Walmart's logistics and inventory management, through tools like handheld computers and RFID networks. The document further describes Walmart's supply chain processes, such as its fleet of 3,500 owned trucks and cross-docking approach. Finally, it addresses the benefits Walmart gained from its efficient supply chain, including consistent product flow, lowest product costs, and a demand-driven rather than supply-driven system.
