Lingo error 63模型定义不正确

Answer 1

只能在语法上改 没有可行解 自己看看你写的约束对不对吧

model:

sets:

xx/v1..v14/:p,q;

xi/w1..w7/:c;

xn(xx,xi):x;

endsets

min=@sum(xx(k):x(k,1)*p(k)*q(k));

@for(xx(J):@sum(xi(I):x(J,I))=1);

@for(xi(I):@sum(xx(J):x(J,I)*p(J))=0);

@for(xn:@BIN(x));

data:

p=688 780 528 388 328 400 420 580 880 1760 620 480 1620 132;

q=5.9186 4.7 5.7 11.148 11.902 4.32 8.3857 10.571 18.427 6.3125 7.1194 11.7 9.006 0;

c=1760 1320 1320 1760 1320 1320 1320;

enddata
