标题: 菜鸟优化问题在线求找错！！
两辆货车，装7种类型的箱子，只计箱子厚度，每辆车长1020CM，重40T，每种箱子有数量限制，而且5.6.7号箱子一共长度不能超过302.7cm………………大概就是这样。
我是初学，各位高手帮帮忙，看我下面程序哪错了。

model:
sets:
  car/1..2/;
  goods/1..7/:t,w,n;
  ren(car,goods):x;
endsets

min=2040-@sum(ren(i,j):x(i,j)*t(j));
@for(ren

bin(x));
@for(car(i)

sum(goods(j):x(i,j)*t(j))<=1020);
@for(car(i)

sum(goods(j):x(i,j)*w(j))<=40000);
@for(goods(j)

sum(car(i):x(i,j))<=n(j));
@sum(ren(i,j)|j#ge#5:x(i,j)*t(j))<=302.7;

data:
  t=48.7 52 61.3 72 48.7 52 64;
  w=2000 3000 1000 500 4000 2000 1000;
  n=8 7 9 6 6 4 8;
enddata
end
