Dear friend,how to write equations in the condition of the binary varible equal to 1 in GAMS,thanks very much~

Dear friend,
Hi!
I have some troubles in writing equations in the condition of the binary varible,here is the the problem:
the j is the index of consumers,and the t is the index of the time,v is the binary varible to describle the state of the shifted load,and the Q1(j,t) is the capacity of shifted load.

I try to write some equations following to express if v(j,t) eq 1,then [Q1(j,t)=g=-Q1_max(j) && Q1(j,t)=l=0],if v(j,t)=0,then [Q1(j,t)=g=0 && Q1(j,t)=l=Q1_min(j)],however,the equations are wrong,I wonder how to correct it,thank you,friend~

DRcondition(j,t)… if v(j,t) eq 1,then Q1(j,t)=g=-Q1_max(j);
DRcondition1(j,t)… if v(j,t) eq 1,then Q1(j,t)=l=0;

DRcondition2(j,t)… if v(j,t)=0,then Q1(j,t)=g=0;
DRcondition3(j,t)… if v(j,t)=0,then Q1(j,t)=l=Q1_min(j);

Best wishes to you,
River

Hi River,

Try this two constraints:

Const_1(j,t)… Q1(j,t) =G= -Q1_max(j)v(j,t);
Const_2(j,t)… Q1(j,t) =L= Q1_min(j)[1 - v(j,t)];


Cheers,
Pedro

Dear Pedro:
Thanks for your suggestion I have adopted,which the results are reasonable in GAMS,thank you very much!~
Best wishes,
River
