Question

lingo@sum怎么总是错误

model:
sets:
S/S1..S4/:SI;
D/D1..D4/:DJ,R,Y;
LINKS(S,D):C,A,U,X;
ENDSETS
DATA:
SI=10,50,200,100;
DJ=10,100,200,50;
C=0,60,50,0
40,0,30,200
0,100,120,80
0,240,210,70;
R=200,160,180,220;
A=0,1,1,0
1,0,1,1
0,1,1,1
0,1,1,1;
U=0,10,10,0
10,0,50,50
0,100,200,50
0,100,100,50;
ENDDATA
MIN=@sum（LINKS(I,J):C(I,J)*X(I,J)）+ @SUM（D(J)：R(J)*Y(J)）；
@FOR（S(I)：@SUM（D(J)：X(I,J)*A(I,J)）<= SI(I)）；
@FOR（D(J)：@SUM（S(I)：X(I,J)*A(I,J)）+Y(J) = DJ(J)）；
@FOR（LINKS(I,J)：X(I,J) <= U(I,J)）；
END

MIN=@sum（LINKS(I,J):C(I,J)*X(I,J)）+这一行有错

Answer 1

Answer 2

那你具体怎么写的 最好写出完整的来

追问

MIN这一行有错误 不知道在哪儿
