Loop Statements

GAMS
1

Hi All,

I want run the Gams model two times. In the first run a dummy district demand is 0 and in the second run the dummy district demand is 68% of total allocation in first run of a particular plant.
I tried to use the loop condition to solve this but could not find the right code.
Can Any body share some idea or code regarding this.

Thanks and regards.
Dharmender Y.

can you post your code for reference, since I don’t really understand what you need.

dharmender yadav,

try something like this:

…

set run / 1*2 / ;
parameter dummy(run);

dummy(‘1’) := 0;
dummy(‘2’) := 0.68;

loop(run,
solve MODEL using NLP minimizing objective
);
