Now in its third edition, Ted G. Eschenbach's Engineering Economy: Applying Theory to Practice continues to solidify its reputation as one of the most innovative, authoritative, and reliable texts in Engineering Economics. It provides the tools and concepts--including cost estimating, sensitivity analysis, probability, and multiple objectives--that are necessary to successfully apply engineering economy in industry practice outside of the classroom.

Designed to emphasize the strengths of traditional factors and of spreadsheet coverage, Engineering Economy: Applying Theory to Practice, Third Edition, is an ideal text for undergraduate and beginning graduate-level Engineering Economy courses.

Ted G. Eschenbach, P.E., is a consultant and Professor Emeritus of Engineering Management at the University of Alaska Anchorage. He received his Ph.D. in industrial engineering from Stanford University and his M.C.E. degree from the University of Alaska Anchorage.
