Frank H. T. Rhodes Hall 253


E-commerce is a business domain that is rapidly evolving, hyper-competitive and presents very challenging complexities to the supply chain management professional. In this talk we will review the innovations Walmart is developing to transform itself from a “bricks and mortar” retailer to a global, digitally-enabled, omni-channel business. We’ll dive deep into a few specific examples of how big data and quantitative methods are being used to optimize its supply chain network, inventory management policies and speed the delivery of merchandise to its customer. We’ll also explain, through Project Gigaton, how Walmart is influencing its numerous supplier-partners around the world to reduce CO2 emissions and achieve significant and specific environmental goals.
