Sensitivity and solution space

**abha** · 11-19-2011, 11:58 AM

i have a coursework on linear programming , decision optimisation. I have maximised my objective using solver .I even have a limit,answer and a sensitivity report but i cant interpret them.How to make conclusions from them .Next my problem is that i have to do sensitivity and solution space .Can you give me any links/tutorial/site explaining me hoe to do all of these(sensitivity,solution space) .Or can you explain yourself.I will be very greatful to you.

Hi abha and welcome to the forum,

My answer to understand new stuff is to read many different authors. Sometimes the book the prof uses makes no sense but some web page is perfect for your brain. Try these three sites:
First with an example:
http://people.brunel.ac.uk/~mastjjb/...ns_solver.html
Second a pdf file that says this is complicated when dealing with the real world
http://www.econ.ucsd.edu/~jsobel/172aw02/notes7.pdf
Third a web page

Press the reply button. The paper clip button is next to the smiley face.

here is my file with the sensitivity report.Please explain what reduced gradient ,lagrange multiplier means.And what does binding and not binding means in the answer report status .Lastly can you tell me that you do think that i used solver correctly to maximise my chess ratings.
