Hi,
I want to give limit to variables like below.
Q(i,j,K) is positve variable. But this variable is zero when the
binary variable Z(i,j,k) is zero.
I want to give lower limit but only Z(i,j,k) is not zero.
for exmaple Q.lo(i,j,k)=30 when Z(i,j,k) is not zero…
How can I express in GAMS?

Hi
add following constraints:
q >= 30 * z
q= 0 and q= 30 and q wrote:

Sung,
You may add the following equation to your model:
EQUATION Qmin(i,j,k);
Qmin(i,j,k) …
Q(i,j,k)=30*Z(i,j,k);
MODEL / , Qmin/
I hope this helps.
