1 某厂每日8小时的产量不低于1800件. 为了进行质量控制，计划聘请两种不同水平的检验员。一级检验员的标准为：速度25件/小时，正确率98%，计时工资4元/小时；二级检验员的标准为：速度15小时/件，正确率95%，计时工资3元/小时。检验员每错检一次，工厂要损失2元。为使总检验费用最省，该工厂应聘一级、二级检验员各几名？.

解：

代码：1

model:

min=40*x1+36*x2;

200*x1+120*x2>1800;

@for(@gin(x1);@gin(x2););

end

代码2：定义集合段

model:

sets:hang/1/:a;

     lie/1..2/:b,x;

     xishu(hang,lie):c;

endsets

data:

a=1800;

c=200 120;

b=40 36;

enddata

      min=@sum(lie:b*x);

      @for(hang(i):@sum(lie(j):c(i,j)*x(j))>a(i));

      @for(lie:@gin(x));

End
