{\Large \bf Comments on Case Study \#2}

\noindent
Overall, these were done quite well. Everyone seemed to be able to
handle using MATLAB and MAXDET. For the most part the case studies
were written up in a very clear manner. A couple of points though for
the next case study. Make sure when you indicate what the model is in
mathematical terms that you explain how that model represents the
problem you are trying to solve, i.e. give the details about how it
was developed. When you get an answer, don't assume that the software
automatically gives you the right answer. Check the solution for
things like primal feasibility, dual feasibility and complementary
slackness. And then check the duality gap to see how {\bf good}   a
solution you actually have. Finally, the more sensitivity analysis you
can include, the better.
