model:
sets: center/1..3/:u;
addr/1..7/:v;
w(center,addr):x,y;
endsets
data: y= 36 24 49 21 81 72 45
30 20 56 24 99 88 55
36 24 63 27 90 80 50 ;
enddata

@sum(addr(j):x(1,j))=3;
@sum(addr(j):x(2,j))=2;
@sum(addr(j):x(3,j))=2;
@for(addr(j):@sum(center(i):x(i,j))=1);
@for(w:@bin(x));end结果： Global optimal solution found. Objective value: 329.0000 Objective bound: 329.0000 Infeasibilities: 0.000000 Extended solver steps: 0 Total solver iterations: 0 Variable Value Reduced Cost U( 1) 0.000000 0.000000 U( 2) 0.000000 0.000000 U( 3) 0.000000 0.000000
