求帮忙看看这个lingo程序那里错了。总是要报语法错误，刚刚开始学，所以不太懂。

MODEL:

sets:

q/1/;
points/1..12/;
edges/1..19/;

roads(points,points): X;
flow(points,q): B;
capacity(q,edges): C;
network(points,edges): N; !矩阵的设置，额，不知道为什么有了注释，下面的endsets就要变成绿色。。;

endsets

data:
B =
1

-1;

N =

C = 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1;
Enddata

min=@sum(roads:C*X);

@for(points(i)| N(i,j)*X(i,j) #eq# B(j,1)
@for(points(i)|X(i,j) #eq# 1 #OR# X(i,j) #eq# 0);
END

C和X下标不同不知道你怎么求和的
另外你的集循环函数写的不对 集循环函数里面的约束直接写普通的等式或者不等式就行了 限制为0-1变量用@bin 这个应该一开始学首先就知道了 不知道你那种表达是什么意思

model: sets: qiefa/1,2,3/:x; bujian/1..4/:l,need; shuliang(qiefa,bujian):n; endsets data: l=4, 5, 6, 8; need=50, 10, 20, 15; yuanliaol=19; enddata !这行写错了，已改; min=@sum(qiefa:x); @for(bujian(j):@sum(qiefa(i):n(i,j)*x(i))>need(j)); @for(qiefa(i):@sum(bujian(j):n(i,j)*l(j))16); @for(shuliang:@gin(n)); @for(qiefa:@gin(x)); end
