Operations Management CD

The Course CD (distributed in class) has:

POM-QM can be installed on your own computer from the CD that came with the Heizer-Render text.
Remember, you can't install anything on the school computers.
You can also download demo version 8 of EXTEND from the vendor. These also must be installed. These run under Vista/win 7.

Imagine That! Website with more EXTEND Resources. Demo V8  is under the downloads link, but you have to install it and models can't be saved.

<>POM-QM upgrades from Prentice-Hall  must be installed.   http://wps.prenhall.com/bp_weiss_software_1/0,6750,91664-,00.html

LP Diet problem from Heizer-Render  Get dietLPstart5320.xls I've done most of the configuration and POM solution for you
Description of LP Diet problem 
From the Heizer-Render Textbook
Dietdata copy from pdf at H-Z website and parse into EXCEL. It's easier to copy it from the handout, but this video shows how to get data from a PDF.
 After pasting into EXCEL, Parse by data/ text to columns.
Easier way--pasting and parsing data into excel from the assignment webpage parsdiet

For some reason I don't understand there is a reproducible problem in the school system with EXCEL 2007 that an attempt to generate  sensitivity data in EXCEL SOLVER at this point results in an out-of-memory error.
I have reproduced this problem in Vista and EXCEL 2007 on my own system, so made a video for it. The workaround is to solve without sensitivity analysis, then re-solve and get the sensitivity analysis.The second time around, it works. 
you have to go through a full cycle to a successful solution before going back to get the sensitivity report. That is, solve without asking for sensitivity, then go back into solver and solve again, this time asking for the sensitivity report.
If you solve, ask for sensitivity, get the error, then solve again and again ask for sensitivity, you will have an endless cyle of errors. Remember: insanity is doing the same thing repetitively and expecting something different to happen.

I've not yet reproduced this problem in EXCEL SOLVER 2010, but there are other issues.
