Given the obtained results, the five methods—M
1
, M
2
, M
3
, M
4
,
and M
5
—have the same value (equal to 100) for the family F
1
.
For the family F
2
, the best value R
j,k
(equal to 100) is obtained for
both methods M
3
and M
5
. Consequently, these two methods are con-
sidered the best compared to other methods in this family.
At the level of the family F
3
, the method M
4
is better than the two
methods M
3
and M
5
, but it is clearly much better compared to the
other two methods, M
1
and M
2
.
5.3.4 Comparison of the Methods by Outranking Relation
We will compare the effectiveness of the five methods using out-
ranking relations. ...
