### Using 2 dimensional sets

Posted:

**Fri Jul 06, 2018 10:22 am**Hi,

I would like to define a 2 dimensional set, use it as a variable index and use them in an equation. But I get error using following lines:"Dimensions different"

sets

f /1*3/

r /1*3/

fr(f,r) /1.1

2.(1,2)

3.(1,3)/;

binary variables

v(f,r,gb);

equatios:

e7(d,gb).. k(d,gb)=e= sum(fr,(1-min(abs(mod(d,f)-r),1))*v(fr,gb));

Could anyone help me with please?
