lingo问题

Maxz=(1.25-0.25)*(x1+x2)+(2-0.35)*(x6+x7)+(2.8-0.5)*x9-(5*x1+10*x6)*0.05-(7*x2+9*x7+12*x9)*0.0321-(6*x3+8*x8)*0.0625-(4*x4+11*x9)*0.1119 -7*x5*0.05
s.t 5*x1+10*x6<=6000
7*x2+9*x7+12*x9<=1000
6*x3+8*x8<=4000
4*x4+11*x9<=7000
7*x5<=4000
x1+x2=x3+x4+x5
x6+x7=x8
x1,x2,x3,x4,x5,x6,x7,x8,x9>=0
最优解是多少，此时x1，x2.......x7是多少

Answer 1

X1 1200.000
X2 0.000000
X3 518.5185
X4 110.0529
X5 571.4286
X6 0.000000
X7 111.1111
X8 111.1111
X9 0.000000

如果必须要取整数，则：

X1 1200.000
X2 0.000000
X3 518.0000
X4 111.0000
X5 571.0000
X6 0.000000
X7 111.0000
X8 111.0000
X9 0.000000
