Saul I. Gass received his B. S. in Education and M. A. in Mathematics from Boston University, and his Ph. D. in Engineering Science/Operations Research from the University of California, Berkeley.  He is currently Professor Emeritus at the Robert H. Smith School of Business, University of Maryland, College Park. Dr. Gass first served as a mathematician for the Aberdeen Bombing Mission, U. S. Air Force, and then transferred to Air Force Headquarters where he began his career in operations research with the Directorate of Management Analysis, the organization in which linear programming was first developed. For IBM, he was an Applied Science Representative, Manager of the Project Mercury Man-in-Space Program, and Manager of IBM's Federal Civil Programs. He was a member of the Science and Technology Task Force of the President's Commission on Law Enforcement. He was Director of Operations Research for CEIR, Senior Vice-President of World Systems Laboratories,and Vice-President of Mathematica. He has served as a consultant to the U. S. General Accounting Office, Congressional Budget Office, the National Institute of Standards and Technology, and other operations research and systems analysis organizations. Included in his many publications are the texts Linear Programming (fifth edition) and Decision Making, Models and Algorithms, and the book An Illustrated Guide to Linear Programming. He is co-author of the book An Annotated Timeline of Operations Research: An Informal History. He is co-editor of the Encyclopedia of Operations Research and Management Sciences and A Guide to Models in Governmental Planning and Operations. Dr. Gass is a past president of the Operations Research Society of America (ORSA) and Omega Rho, the international operations research honor society. He served as vice-president for international activities of the Institute of Operations Research and the Management Sciences (INFORMS), and vice-president of the International Federation of Operational Research Societies (IFORS). He is a recipient of ORSA's Kimball Medal for distinguished service to the society and the profession, INFORMS's Expository Writing Award for publications in operations research that have set an exemplary standard of exposition, and the Military Operations Research Society's Jacinto Steinhardt Memorial Award for outstanding contributions to military operations research. He is a Fellow of INFORMS. He was a Fulbright Research Scholar at the Computer and Automation Research Institution, Hungarian Academy of Sciences. He is currently a Fulbright Senior Specialist. Dr. Gass is a University of Maryland Distinguished Scholar-Teacher and the Dean's Lifetime Achievement Professor for the Robert H. Smith School of Business.Dr. Michael Fu received his M.S. and PhD. degrees in applied mathematics from Harvard University in 1986 and 1989, respectively. He received S.B. andS.M. degrees in electrical engineering and a S.B. degree in mathematics from the Massachusetts Institute of Technology in 1985. Since 1989, he has been at the University of Maryland in the Robert H. Smith School of Business.Dr. Fu is a member of IEEE and the Institute for Operations Research and the Management Sciences (INFORMS). He is currently the Stochastic Models and Simulation Department Editor of Management Science, was Simulation Area Editor of Operations Research from 2000-2005, and has served on the Editorial Boards of the INFORMS Journal on Computing, Production and Operations Management, and IIE Transactions. He was named a Distinguished Scholar-Teacher at the University of Maryland for 2004-2005.In 1995, he received the Maryland Business School's annual Allen J. Krowe Award for Teaching Excellence. He is the co-author (with Jian-Qiang Hu) of the book, Conditional Monte Carlo: Gradient Estimation and Optimization Applications(1997), which received the 1998 INFORMS College on Simulation Outstanding Publication Award. Other awards include the 1999 IIE Operations Research Division Award and a 1998 IIE Transactions Best Paper Award. In 2002, he received ISR's Outstanding Systems Engineering Faculty Award, and in 2004-2005 he received the University of Maryland's Distinguished Scholar-Teacher Award.

From the book reviews: "By supplying clear overviews of critical conversations from the diverse disciplines that participate in OR/MS, and by integrating lists of references to support additional exploration, the editors and their contributors provide an accessible gateway to the larger realm of scholarly work in this field. Recommended not only for institutions with OR/MS programs or practitioners but also for those with an interest in exploring the intersections of OR/MS with its many related fields."
