Application Software

GAMS/ZOOM (coauthor), The Scientific Press, 1992. GAMS/ZOOM is an
adaptation of ZOOM to work with GAMS, a high level language developed by A.
Meeraus and A. Brooke of the World Bank.

Lead author of ZOOM (zero-one optimization methods).
The ZOOM software accompanies Dr. Singhal's paper in the ORSA Journal on
Computing, and it has been used by several thousand organizations for successful
applications as a stand-alone system or as a part of other packages. Some of the decisions
involved millions, and in some cases billions, of dollars. ZOOM, has been used for
3
teaching and Ph.D. dissertation research at a number of universities, including Carnegie
Mellon, Minnesota, Princeton, Purdue, Stanford, and the Wharton.
Real world applications: ZOOM has been used for solving large scale mixed integer
programming problems, some involving hundreds of millions or even billions of dollars,
by many corporations and the agencies of the federal government. They include World
Bank, General Motors, Lufthansa German Airlines, Rand Corporation, DOW USA,
Chemical Bank, Martin Marietta Energy Systems, American Express Company,
Universal Foods Corporation, Mitre Corporation, Weyerhauser Technology Center,
Brookhaven National Laboratory, U.S. Geological Survey, Educational Testing Service,
U.S. Department of Defense, U.S. Military Academy, Bell Atlantic Company, Defense
Logistics Agency, GTE Lab, and U.S. Center of Naval Analysis.
Decision support systems using ZOOM: ZOOM has been an integral part of the
following user oriented decision support systems: IFPS/OPTIMUM distributed by
Execucom, MAINPLAN (Maintenance Planning) distributed by Energy Management
Associates, BONDOPS distributed by BARRA, HYDROMAX distributed by
Environmental Research & Technology, and GAMS/ZOOM published by the Scientific
Press. GAMS/ZOOM, an adaptation of ZOOM, uses a high level language for
formulating models that are easily read by modelers and computers alike, easily
modified, and easily moved from one computer environment to another.
ZOOM as a research tool for other scholars: ZOOM has been, and remains, the only
general-purpose mixed integer optimizer for which the source code has been made
available to researchers. As such it has been of great use to Ph.D. students in business and
engineering. Many scholars all over the world are also using her work, including the
software, for further research. They include Bernhard Korce, University of Bonn, West
Germany; Martin Grotschel, University of Augsburg, West Germany; Yoshiko
Wakabayashi, University of Saopsulo, Brazil; Jaume Barcelo, University of Barcelona,
Spain; and many others in the United States at Stanford, Princeton, Minnesota, Wharton
School, Purdue, and Carnegie Mellon.
ZOOM has several thousand users. A partial list is given in the appendix.
