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
Draw n axes with beginning in point S. All axes have
the same length.
Find ideal values for each criterion - set and
basal values for each criterion – set
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.
For the variant make
a mark for each value xij on j-th axis and connect all n mark
for the ai variant.
Repeat the step 4 for all variants.
