I would like to use only one variable (y) but let it to take integer and positive values for different index values as follows:
Sets
t /140/
pt(t) /110/
it(t) /11*40/;
Positive variable
y(pt);
Binary variable
y(it);
Is there a way to do this without defining two separate variables (i.e. y1 and y2)?
Thanks so much…

Dilek,
Have a look at the model LRS in the GAMS model library: it explains how to use priorities to do what you ask about.
