All the materials on this site are free. Because they
are free, the materials provide easy access to the models
and methods of operations research to students and practitioners.
The Excel add-ins
make it easy to solve small or moderately sized problems
using Microsoft Excel without the expense
of commercial software.
I am retired
from the Operations Research and Industrial Engineering
Group at the University of Texas. I spend much of my
time working on this site and the accompanying
add-ins. I enjoy the work and I feel that I am contributing
to the students, faculty and practitioners in the field
of operations research and application areas that use
the tools described herein.

Publishers of Commercial and Free Software
|I cannot compete with the marvelous implementations of
OR methods that are commercially available. I think my
may increase the market for those who sell OR models and
methods. I am also interested in free OR software, specially
if it is programmed for Excel. Would you be willing to
link to my site, in return for a link to yours? My URL
