lingoerror50,for语句出错
model:
sets:
wh/w1..w6/:ai;
vd/v1..v8/:dj;
links(wh,vd):c,x;
end sets
data:
ai=60,55,51,43,41,52;
dj=25,37,22,32,41,32,43,38;
c=6,2,6,7,4,2,5,9 4,9,5,3,8,5,8,2 5,2,1,9,7,4,3,3 7,6,7,3,9,2,7,1 2,3,9,5,7,2,6,5 5,5,2,2,8,1,4,3;
end data
min=@sum(links(i,j):c(i,j)*x(i,j);
@for(wh(i): @sum(vd(j):x(i,j))<=ai(i));
@for(vd(j): @sum(wh(i):x(i,j))=dj(j));end说倒数第三行的for语句语法错误，但是我找不出来，请大侠指教。
一点点小错误，略作修改。见附件。
运行结果得到一个局部最优值，但可能无意义，它要求所有的X都为0，恐怕不是你想要的结果：

没语法错误了
