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.

Optimization

Mode optimization

zCreate routes from LTL

shipments

zTender routes only if less

cost than LTL

zLane based costs zInvolves an external

transaction

Fleet optimization

zAll shipments must be taken zCost based on dedicated
