2 INFORMS The Successes and Failures of E-Logistics H. Donald Ratliff Regents & UPS Professor of Industrial & Systems Engineering; Executive Director of the Logistics Institute Georgia Institute of Technology President and CEO, Velant, Inc. The Internet is revolutionizing the process and economics of logistics. Twenty years ago, the personal computer launched a new generation of logistics technology based primarily on a decentralized planning model. It empowered sophisticated users to make better decisions by giving them flexible modeling capability, a graphical interface and a moderate amount of computing power. Client-server computers added an element of connectivity that allowed automation of internal company transactions but did little to change decision technology or interactions between companies. E-logistics--the next generation of logistics technology--will be based on a centralized computing model driven by networked computing. In this session, Ratliff will discuss the evolution of this new model, the successes and failures to date, and the technical and operational issues that must be overcome. 2

10 SC Design Software Current Offerings CAPS Logistics I2 Insight Logic Tools Solver engines ILOG - CPLEX Dash Xpress MP Custom Future Requires high modeling expertise Not much change 10

11 Transportation Network Design Pooling networks Pool points UPS facility Postal facility LTL hub Cross-docking networks Focus on LTL shipments Cross-docks are shipper controlled Origins Destinations Cross-docks 11

12 Cross-Docks 12 No planned inventory Unload, sort, stage, load Examples Inbound for retail Wal-Mart Home Depot LTL and package delivery UPS Yellow Freight New cars Ford Operation Schedule-driven Load-driven receiving shipping sort

13 Design Difficulties Origin to destination TL LTL Multi-stop route Origin to cross-dock TL LTL Multi-stop route Cross-dock to destination TL LTL Multi-stop route Routing is difficult Static Dynamic Supply chain design models don t work!!! Cost are very nonlinear Flows are dependent Volume is critical Origins Destinations 13 Technology Inadequate!!! Cross-docks

18 Mode Optimization Versus Fleet Copyright April 2002 H. Donald Ratliff Optimization Mode optimization Create routes from LTL shipments Tender routes only if less cost than LTL Lane based costs Involves an external transaction Fleet optimization All shipments must be taken Cost based on dedicated truck Driver Equipment No external transaction 18 Commercial Carrier Dedicated Fleet

19 Current Technology Map-on-the-wall Map-on-the-computer 19 Visual algorithms Requires smart planner Poor quality Greedy algorithms Requires super-user Marginal quality

27 Transportation Exchanges Vision Sell unused capacity Workload imbalance Backhauls Partial loads Bring together shippers and carriers Many small carriers Many small shippers Reduce cost Brokers fees 13% Increase competition - auctions Leverage information Shippers Exchange Carriers 27

28 Transportation Exchanges More than 100 startups Most are gone Spot market small Too many players Too little experience Weak technology Survivors New business models 28

29 What about the future? Network design Better cross-dock planning technology Problems are really hard Strategic procurement Mostly automation Trends Centralized optimization Optimization outsourcing Limited collaboration Optimization is too hard for carriers Optimization Transportation management centers New generation of technology 29
