Distribution Center Location • Minimize demand-weighted distance: distance to each customer times the volume of shipments to the customer • How many to build? • Where to build?
Case Study: Retailer • Location of a 5th returns processing facility • Addresses of 2125 Continental U.S. stores • Location of 4 Return Goods Processing Centers • List of all return shipments from each store, including pounds and # pallets • Calculated actual highway distances from every store to its DC
Transportation Cost Approx. • Current Pallets: 205,254 • Current Pallet Miles: 77.9m • Cost / pallet-mile 11.68 cents • Pallet-Mile = 1 pallet traveling 1 mile • Minimize average distance traveled
Summary • Transportation costs are a huge factor • Street-level approximation of transportation distances unnecessary • “Straight Line” distances are usually fine • “Great Circle” distances take the curvature of the Earth into account • Both inbound and outbound costs need to be taken into account
