Alice E. Smith, is Professor and Chair of the Industrial and Systems Engineering Department at Auburn University. Previous to this position, she was on the faculty of the Department of Industrial Engineering at the University of Pittsburgh, which she joined in 1991 after 10 years of industrial experience with Southwestern Bell Corporation. She has degrees in engineering and business from Rice University, Saint Louis University and University of Missouri—Rolla. Her research in analysis, modeling and optimization of manufacturing processes and engineering design has been funded by NASA, the National Institute of Standards (NIST), Lockheed Martin, Adtranz (now Bombardier Transportation), the Ben Franklin Technology Center of Western Pennsylvania and the National Science Foundation (NSF), from which she was awarded a CAREER grant in 1995 and an ADVANCE Leadership grant in 2001. International research collaborations have been sponsored by the federal governments of Japan, Turkey, United Kingdom and the US. She has served as a principal investigator on over $3 million of sponsored research. She was named a Philpott-WestPoint Stevens Distinguished Professor in 2001 by the Auburn University College of Engineering. For outstanding achievements in research and scholarly activity she received the annual Senior Research Award of the College of Engineering at Auburn Uni- versity in 2001 and the University of Pittsburgh School of Engineering Board of Visitors annual Faculty Award in 1996. She holds one US patent and several international patents and has authored over 50 publications in journals including articles in IIE Transactions, IEEE Transactions on Reliability, INFORMS Journal on Computing, International Journal of Production Research, IEEE Transactions on Systems, Man, and Cybernetics, Journal of Manufacturing Systems, The Engineering Economist, and IEEE Transactions on Evolutionary Computation. She won the E. L. Grant Best Paper Award in 1999 and the William A. J. Golomski Best Paper Award in 2002. She holds editorial positions on INFORMS Journal on Computing, Computers & Operations Research, International Journal of General Systems, IEEE Transactions on Evolutionary Computation and IIE Transactions. Five of her doctoral students have obtained tenure track positions at US universities and two of these are NSF CAREER awardees. She is a fellow of IIE, a senior member of IEEE and SWE, a member of Tau Beta Pi, INFORMS, NSBE and ASEE, and a Registered Professional Engineer in Industrial Engineering in Alabama and Pennsylvania.

N2 - In this paper, the unequal area facility expansion and relayout problem is studied. The facility relayout problem is important since both manufacturing and service entities must modify their layouts over time when their operational characteristics change. A bi-objective approach is proposed to solve the relayout problem for cases of both a fixed facility area and an expanded facility area. Material handling costs and relayout costs are minimized using a tabu search meta-heuristic optimizer. This heuristic randomly alternates the objective function between the two objectives of the problem in each step and, by doing so, eliminates the difficulty of weighting and scaling the two objectives. The approach is flexible in handling various aspects of the problem such as stationary portions of departments (i.e., monuments), addition of new departments, and changes in existing department and facility areas. Computational experiments show that the bi-objective tabu search approach is effective and tractable. The use of the Pareto front of designs is demonstrated by showing a few approaches to analyzing the trade-offs between initial costs (relayout cost) and ongoing expenses (material handling costs).
