Hi,

sorry about the confusion with the topic, my question was how the parameter could be defined in dependence from a, not aa.

But your answer actually helped already!!

I now wrote:
sets aa / blah blahblah /, a(aa) / blah /;
parameter pa(a), paa(aa);
pa(a(aa)) = paa(aa);

Thank you so much!!

The following parameters are given, with a being a subset of aa. However, all the non-overlapping elements of aa with a are already kicked out of emis2. Hence, the remaining aa and a are basically the same. emis1(r,a,t) emis2(r,aa,t) Now I want to define the dimensions of emis2 dependent from a, not...
