Hello everyone,

I am a professor in Santiago, Chile, and I started using IBM ILOG OPL in my classes. I have a question about the output of an optimization problem.

How can I see the allowable ranges for the right-hand side and for the coefficients of the objective function value after the problem is solved? In Excel Solver this was called "maximum allowable increase" and "maximum allowable decrease". I went through the problem browser, selected a constraint and clicked in a button that shows me the value of the dual variables but I could not find the allowable range.
I wonder if some option has to be added to the code in order to see this information.

Thanks in advance,
Bernardo

Hi,

There are a number of available information for constraints.
They require that you name your constraints, for example :

constraints {
ct: ...
}

Then you can use the problem browser to display additional information in data views.
