求写一段lingo上可以运行的代码。

Question

如题所述

Answer 1

max = x1 + x2 + x3 + x4 + x5;

A = 10000;
x2 = x1;
x3 = 0.98 * x2;
x4 = 0.95 * x3;
x5 =0.80 * x4;
x0 = 1.8 * x2 + 2.4 * x3 + 2.0 * x4 + 1.8 * x5;
n1 = 90 * 3 * A / 1000;
n2 = 90 * 7 * A / 1000;
n3 = 90 * 4 * A / 1000;
n4 = 0;
m1 = (x2 + x3 + x4 + x5) * 2.4 * 90 + x0 * 90;
m2 = (x2 + x3 + x4 + x5) * 1.15 * 90 + x0 * 1.65 * 90;
m3 = (x1 + x2 + x3 + x4 + x5) * 1.35 * 90;
m4 = (x1 + x2 + x3 + x4 + x5) * 2.1 * 90;
m2 <= n2;
m3 <= n3 + n2 - m2;
m3 <= n3 + n3 - m2 - m3;
m1 <= n1 + n2 - m2 + n3 - m3;

运行结果如下：
