Introduction to operation research software packages:
1.TORA 2. LINGO 3. AMPL 4. EXCEL
Introduction:
Operations research uses various optimization algorithms to help make decisions related to highly
complex problems. Operations research (OR) is an analytical method of problem-solving and decision-
making that is useful in the management of organizations. In operations research, problems are broken
down into basic components and then solved in defined steps by mathematical analysis.
Objective
.To be familier with operation research and softwares used to study it
Explanation:
TORA:
TOra is a free software database development and administration GUI, available under the GNU
General Public License. It features a PL/SQL debugger, an SQL worksheet with syntax
highlighting, a database browser and a comprehensive set of database administration tools. In
addition to Oracle Database support, support for MySQL, PostgreSQL and Teradata databases
has been added since the initial launch. It uses the Qt, and can use the qScintilla2 library. The
Oracle connector uses the Oracle Template Library. TOra was originally written by Henrik
Johnson and copyright by GlobeCom AB, which was acquired by Quest Software. Start of
conversion to being maintained as open source project was made on 2005-02-17 with version
1.3.15. QT4 conversion took place in 2009 with version 1.4.Background:
TORA is a free software database development and administration GUI, available under the GNU
General Public License. It features a PL/SQL debugger, an SQL worksheet with syntax highlighting, a
database browser and a comprehensive set of database administration tools
Feature:
 Handles multiple connections.
 Asynchronus database communication. UI mostly responsive when accessing database.
 Requires no installation on the database side to be fully functional.
 Advanced SQL worksheet.
 Code completion(temporarily disabled in version 3.0).
 Explain execution plan.
 Execution statistics.
 Parse error location indicion.
 Chart visualization of result.

 PL/SQL block parsing.
 Table & view editing.
Introduction to LINGO:
Lingo provides a completely integrated package that includes a powerful language for expressing
optimization models, a full featured environment for building and editing problems and a set of fast built
in solvers. lingo is a computer-aided optimization software that solves linear, non-linear, and mixed
integer linear and non-linear programs. It is developed by lingo Systems Inc. ... A trial version for
assessing the software may be downloaded from the lingo Systems web site
Background:
Lingo was invented by John H. Thompson at Macro Mind in 1989, and first released with Director 2.2.
Jeff Tanner developed and tested Lingo for Director 2.2 and 3.0, created custom X Objects for various
media device producers, language extension examples using X Factory including the X Factory
application programming interface (API), and wrote the initial tutorials on how to use Lingo. Dave
Shields tested and documented Object-based Lingo for Director 3.13 and 4.0. He ran build scripts to
create weekly releases for testing, originated the Macromedia Knowledge Base, created examples of how
to write Lingo XTRA plug-ins in C++, and assembled the Golden Master disks of Macromedia Director
that were shipped to the duplicator.
Uses:
 to create user interfaces,
 to make changes in raster graphics,
 learn about vector graphics and 3D computer graphics
