lingo提示错误missing right parenthesis

model:

warhouse/w1..w4/:a,f,g;

tr/tr1..tr4/:z;

@for(factory(k):
@sum(link1(k,i):w(k,i))<=p(k);
@for(warhouse(i):
@sum(link2(i,j):x(i,j))=@sum(link1(k,i):w(k,i));
@for(customer(j):
@sum(link2(i,j):x(i,j))>=d(j));
@sum(warhouse(i):
@sum(link1(k,i):w(k,i))<=(a(i)*z(i)));
@sum(tr(i):z(i))<=3;
@for(tr(i):@bin(z));
end

提示出错的是：@sum(link1(k,i):w(k,i))<=(a(i)*z(i)));
请各位大虾帮忙~~

追问

非诚感谢您~~
这个程序是一篇文献当中的，我用您的程序算了一下，跟文献中给出的答案稍有出入。
请问我给出的程序是哪里出错了呢？

那就不知道了 你自己对照模型看一下跟这个写的是不是一致 我不知道你的问题是什么没法说
