I have this problem with the solver and especially with the sensitivity
report, which I don't know how to fix. My target function is:

max Z = 16x1 + 16x2 +16x3 + 16x4 + 28x5 + 28x6 + 28x7 + 28x8

but the coefficient 16 is not independent from each variable. In other
terms, I have a cost vector which has the values 16 and 28 in it. And these
values are assigned as mentioned above. But when generating a sensitivity
report every coefficient of the variables is assumed to be independent from
each other. Does anybody know if and how I can block these coefficients, so
that the sensivity report doesn't assume independency?
