Question

帮忙看哈下面这个lingo程序哪里有问题,显示第十行出错,求指导~

Answer 1

下标都从1开始

model:

sets:

season/1..4/:x;

fire/1..3/:y;

endsets

min=120+x(1)+x(2)+x(3)+x(4);

120*65+x(1)*60>=6000;

((120+x(1))*0.85-y(1))*65+60*x(2)>=7500;

(((120+x(1))*0.85-y(1)+x(2))*0.85-y(2))*65+60*x(3)>=5500;

((((120+x(1))*0.85-y(1)+x(2))*0.85-y(2)+x(3))*0.85-y(3))*65+60*x(4)>=9000;

end

@gin(x(1));

@gin(x(2));

@gin(x(3));

@gin(x(4));
