Hi,
I have some trouble implementing part of my model:
1) I have this definition of my parameter k
I tried this but it doesn't work (the icdf function is imported)
k(alpha(m)) =e= icdf(alpha(m), 0,1);
2) If have a constraint that is defined for all m in {1,…M-1}. How could I do that?
The relevant Sets/Parameters/Variables are:
Thanks for any help!

Re: Problem implementing a Model
Hi Lizzy
One trick to have an equation only for the M-1 elements is by using the cardinal of a set (the number of elements): card(m) and the order:
With respect to your second question: A variable is defined over a set, e.g. X(i), but can't be defined over a variable itself like you do X(Y).
Correct, but I don't know if this is what you are looking for, is:

Code: Select all
myconstraint(m$(ord(m) ne card(m))..

Re: Problem implementing a Model
Hello,
thanks a lot for the response.
Regarding the first question I'm sorry, I uploaded the wrong picture. So here is the right one: So this is not possible?
I think I have the same problem regarding this constraint:
So there is no chance to implement constraints like this?
Best regards
