MinZ(s)=s1*23+s2*54+(1000-22s1-50s2)*(1+2.5%)1.1*

MinZ(s)=s1*23+s2*54+(1000-22s1-50s2)*(1+2.5%)1.1*

按所占权重算 MinZ(s)=s1*23+s2*54+(1000-22s1-50s2)*(1+2.5%)1.1* s1*22/10000+1.3* s2*50/10000+0* s3/10000≤0.80≤s1*22/10000≤10≤s2*50/10000≤10≤（1000-22s1-50s2）/10000 ≤1s1,s2要求是整数（这也是条件之一）最好能把画出的坐标图也传上来那个题开始打错了，是要求目标函数(图1)答案网 www.Zqnf.com 答案网 www.Zqnf.com ======以下答案可供参考======供参考答案1:min=s1*23+s2*54+(1000-22*s1-50*s2)*(1+0.025);1.1* s1*22/10000+1.3* s2*50/10000s1*22/10000s1*22/10000>=0;s2*50/10000>=0;s2*50/10000(1000-22*s1-50*s2)/10000 (1000-22*s1-50*s2)/10000>=0;@free(s1);@free(s2);@gin(s1); ！定义s1为整数@gin(s2); ！定义s1为整数这是用lingo做的。很简单，其他方法就复杂了；结果如下：Global optimal solution found. Objective value: 1025.000 Extended solver steps: 0 Total solver iterations: 0 Variable Value Reduced Cost S1 0.000000 0.4500000 S2 0.000000 2.750000即：是s1=0，s2=0时有最小值1025

你的回答很对
