你写的是lindo的程序，而lingo的程序是这样的：
max = 1058400*x21+185600*x22+1996800*x23+2271200*x24+2492000*x25+1310400*x26;
x21*(x21-50)>=0;
x21*(x21-500)<=0;
x22*(x22-150)>=0;
x22*(x22-500)<=0;
x23*(x23-100)>=0;
x23*(x23-550)<=0;
x24*(x24-150)>=0;
x24*(x24-350)<=0;
x25*(x25-50)>=0;
x25*(x25-450)<=0;
x26*(x26-100)>=0;
x26*(x26-250)<=0;
@gin(x21);@gin(x22);@gin(x23);@gin(x24);@gin(x25);@gin(x26);
结果是：
Global optimal solution found.
Objective value: 0.3964160E+10
Objective bound: 0.3964160E+10
Infeasibilities: 0.000000
Extended solver steps: 1
Total solver iterations: 57
Variable Value Reduced Cost
