Example 1 Solve by using graphical method Max Z = 4x 1 + 3x 2 Subject to 4x 1+ 3x 2 ≤ 24 x 1 ≤ 4.5 x 2 ≤ 6 x 1 ≥ 0 , x 2 ≥ 0 Solution Lecture 4 Special Cases in Graphical Method Linear Programming : The first constraint 4x 1+ 3x 2 ≤ 24, written in a form of equation 4x 1+ 3x 2 = 24 Put x 1 =0, then x 2 = 8 Put x Example : A small business enterprise makes dresses and trousers. Why linear programming is a very important topic? Solvedifficult problems: e.g. Lesson 3: Graphical method for solving LPP. To make a dress requires 2 1 hour of cutting and 20 minutes of stitching. Learning outcome 1.Finding the graphical solution to the linear programming model Graphical Method of solving Linear Programming Problems Introduction Dear students, during the preceding lectures, we have learnt how to formulate a given problem as a Linear Programming model. For example if the objective function is:f=60x1+40x2And the constraints are:2x1+3x2≤80 5x1+4x2≤80 x1≥0 x2≥0The normal form of the linear programming problem would be: There are two methods for solving linear programming problems: Graphical method and simplex method. 1 HOW TO SOLVE A LINEAR PROGRAMMING PROBLEM Method 1: Graphic 2 iClicker policy … In this article, we will solve some of the linear programming problems through graphing method. We indicate the feasible half with arrows. Cuttingapaperrollinpiecesto Let us turn inequalities into equalities and draw lines on the coordinate system. The Graphical Simplex Method: An Example (x1;x2) is a point in the coordinate system. LINEAR PROGRAMMING : Some Worked Examples and Exercises for Grades 11 and 12 Learners. LINEAR PROGRAMMING: EXERCISES - V. Kostoglou 18 PROBLEM 10 Solve using the Simplex method, the following linear programming problem: max f(X) = 7/6x 1 + 13/10x 2 with structure limitations : x 1 /30 + x 2 /40 1 x 1 /28 + x 2 /35 1 x 1 /30 + x 2 /25 1 and x 1, x 2 0 2.
