You should define your constraint per user group ("Altersgruppe"):

*NB..
*sum(t$(ord(t)<=ord(i)), b(j,t)) =e= a(t);
NB(i)..
sum(j,b(i,j)*x(j))=e=1;

Re: Dynamic subset as input extracted from solutions in a two phase model
in mode2 you only want the plants and destinations of that cluster
in all equations of model2 add the conditional $B.l(c,i,j)
and I would change that last loop into:
Loop (c$CC(c),
Solve Model_2 for each cluster.
Display results;
);

Re: Choosing columns so that sum(rows) are equal 1
you need to use mixed integer programming instead of linear programming

Re: how to uses ord on a dynamic set
The trick is not to loop over the dynamic set but over the constant set using the dynamic set as a conditional scalar timestep /3/ ; Set Year /2014*2033/ delayYr(year) ' Years' ; delayYr(year)$(mod(ord(year)-1,timestep)=0)=Yes; display delayYr; scalar val; loop(Year$delayYr(year), val = ord(year); d...
