幫忙編壹下下圖的數學建模lingo程序。謝謝啦。

max=12*x1+7*x2+6*x3-(10*y11+9*y12+8*y13+7*y14)*x1-(6*y21+4*y22+3*y23)*x2-(3*y31+4*y32)*x3;

x1+2*x2+x3<=100;

10*x1+4*x2+5*x3<=700;

3*x1+2*x2+x3<=400;

41*y12+191*y13+151*y14<=x1;

40*y11+100*y12+150*y13+M*y14>=x1;

51*y22+101*y23<=x2;

50*y21+100*y22+M*y23>=x2;

101*y32<=x3;

100*y31+M*y32>=x3;

y11+y12+y13+y14=1;

y21+y22+y23=1;

y31+y32=1;

@gin(x1);@gin(x2);@gin(x3);

@bin(y11);@bin(y12);@bin(y13);@bin(y14);@bin(y21);@bin(y22);@bin(y23);@bin(y31);@bin(y32);
