帮我看看lingo程序有没问题.说是@for语句不当
model:
sets:
liaochang/1,2/:x,y,e;
gongdi/1..6/:a,b,d;
links(liaochang,gongdi):c;
endsets
min= @sum(links:c(i,j)*((x(i)-a(j))^2+(y(i)-b(j))^2);

哪里有悬赏分啊?
是你的逻辑错误：工地与料场直接的关系不准确?
之前出现的@for问题是因为你上面少了一个括号!所以就出现@for,修改了括号就出现逻辑问题了!
直接修改：
model:
sets:
gongdi/1..6/:a,b,d;
liaochang/1..2/:x,y,e;
link(gongdi,liaochang):c;
endsets
data:
a=1.25 8.75 0.5 5.75 3 7.25;
b=1.25 0.75 4.75 5 6.5 7.75;
d=3 5 4 7 6 11;
e=20 20;
enddata
min=@sum(link(i,j):c(i,j)*((x(j)-a(i))^2+(y(j)-b(i))^2)^(1/2));
@for(gongdi(i):@sum(liaochang(j):c(i,j))=d(i););
@for(liaochang(i):@sum(gongdi(j):c(j,i))
