那位知道下面的lingo程序错在哪

model:
sets:
warehouse/1..3/:a;
customer/1..4/b;
routes(warehouse,customer):c,x;
endsets
data:
a=30,25,21;
b=15,17,22,12;
c=6,2,6,7,
4,9,5,3,
8,8,1,5;
enddata
[email=min=@sum(routes:c*x]min=@sum(routes:c*x[/email]);
@for(warehouse(i):
@sum(customer(j):x(i,j))<=a(i));
@for(customer(j):
@sum(warehouse(i):x(i,j))=b(j));
end

第四行少加了个冒号，[email=min=@sum(routes:c*x]min=@sum(routes:c*x[/email]);这个语句是什么？看不懂。好像应该是min=@sum(routes:c*x);这么改了就能够运行了

二楼说的对，我刚才验证过了，就两个错误。

就是二楼说的那样，这个好像是个优化问题（关于房屋分配的）
