Write the following LP in canonical inequality form ie formu
Write the following LP in canonical inequality form (i.e., formulate an equivalent LP that has canonical inequality form):
min 2x1 + x2 + x3
s.t. 4x1 + 3x2 + 2x3 3
2x1 x2 3x3 1
x1 + x2 + x3 = 1
x1 0
x2 7
0 x3 3.
Solution
we have to cange the given inequality constraintsin lpp into canoniaclal form so
1. objective should be Max.
2. inequality should be <= constraints
3. variables must be non negative
give,
w=min (-2x1+x2+x3)
st 4x1+3x2+2x3<=3
2x1-x2-3x3>=1
x1+x2+x3=1
x1>=1
x2>=-1
<=x3<=3
Max(z=-w= 2x1-x2-x3)
st
4x1+3x2+2x3<=3
-2x1+x2+3x3<=-1 {negative of second constraints}
x1+x2+x3<=1 { break in two parts <= and >= }
-x1-x2-x3<=-1
-x1<=0
-x2<=7
-x3<=0 { break into two parts x3>=0 ,x3<=0 }
x3<=3
