In this video I have explained you problem of Linear Programming using GRAPHICAL METHOD which will help you to understand concepts of Graphical Method in detail and easy way ,video is on maximization problem with 3 constraints and two variables.
About GRAPHICAL METHOD In Linear Programming Problem :
Step1: Consider each inequality as an equation.
Step2: Shade the feasible region :
i) If the inequality constraint with a sign ' greater than '.Then the region above the line in the first quadrant will be shaded.
ii) If the inequality constraint with the sign ' less than '.Then the region below the line in the first quadrant will be shaded.
iii) If the inequality constraint with the sign' ='.Then solution will exist on the line.
Step 3: The common region obtained is called the FEASIBLE REGION.
Step 4: Find the value of corner points and the corresponding value of objective function 'z' for corner points of the feasible region.
Step5: Find a Maximum value of z and the corresponding value of points.This is OPTIMAL SOLUTION.
