Consider the following LP

maximize 20*A+10*C;

subject to {
a: A+2*C <= 120;
b: A+ C <= 90;
c: A <= 70;
d: C <= 50;
}

Solving the LP using solver in Excel provide us with a sensitivity report (see attatchment).

Is there any way to get the same info in the IDE (using script it seems that you only have access to reduced cost and duals).

Best

Hi,

if you write

dvar float+ A[1..1];
dvar float+ C[1..1];
 
maximize 20*A[1]+10*C[1];
 
subject to {
forall(i in 1..1) a:A[i]+2*C[i] <= 120;
forall(i in 1..1) b: A[1]+ C[1] <= 90;
forall(i in 1..1) c: A[1] <= 70;
forall(i in 1..1) d: C[1] <= 50;
}

then in the problem browser you can get some information by clicking on A,C,a,b,c and d

The approach Alex suggested does not really help if you want to
further process the results from sensitivity analysis.
As far as I know you will have to switch to Java to do
full sensitivity analysis.
Please have a look at ,e.g., IloCplex.getObjSA() in the documentation.
