怎么来解决？
谢谢了，各位！

model:

sets:

si/1..4/:cl;

sj/1..4/:xl;

sij(si,sj):c,x;

endsets

data:

xl=1 1 1 1;

cl=1 1 1 1;

c=15 18 21 24

19 23 22 18

26 17 16 19

19 21 23 17;

enddata

min=@sum(sij:c*x);

@for(sj(j):@sum(si(i):x(i,j))=xl(j);

@for(si(i):@sum(sj(j):x(i,j))=cl(i);

@bin(x(i,j));

end

model:
sets:
si/1..4/:cl;
sj/1..4/:xl;
sij(si,sj):c,x;
endsets
data:
xl=1 1 1 1;
cl=1 1 1 1;
c=15 18 21 24
19 23 22 18
26 17 16 19
19 21 23 17;
enddata
min=@sum(sij(i,j):c*x);
@for(sj(j)sum(si(i):x(i,j))=xl(j););
@for(si(i)sum(sj(j):x(i,j))=cl(i););
@for(sij(i,j)bin(x(i,j)));
end
这样子就可以了。
