Graphical Presentation of MADM Model

We can use a system of star axes. All axes begin in the point S. The number of axes is equal to the number of criteria a and each two axes contain angle of .

Steps for Creating Star Graph:

  1. Draw n axes with beginning in point S. All axes have the same length.
  2. Find ideal values for each criterion - set and basal values for each criterion set 
  3. Make a linear graduation on each j-th axis with beginning in the point S with the value Dj and end at the end of axis with value Hj.
  4. For the variant make a mark for each value xij on j-th axis and connect all n mark for the ai variant.
  5. Repeat the step 4 for all variants.
