Unit 2: Linear Programming Problems




          Step 3: Graph the data                                                                Notes






































          Step 4: Find the co-ordinates of the corner points
                     Corner Points                x1                     x2
                         A                        1.5                    0
                         B                        3                      0
                         C                        3                      3
                         D                        0                      3
                         E                        0                      1
          Step 5: Substitute the co-ordinate of the corner points to the objective function.

                                   Z = 5x  + 3x
                                         1   2
                              At ‘A’, Z = 5(1.5) + 3(0) = 7.5
                              At ‘B’, Z = 5(3) + 3(0) = 15

                              At ‘C’, Z = 5(3) + 3(3) = 24
                              At ‘D’, Z = 5(0) + 3(3) = 9
                              At ‘E’, Z = 5(0) + 3(1) = 3

          Inference

          Maximum profit  (`  24) can be gained  by  producing  3 units  of product ‘M’ and  3 units  of
          product ‘N’.
