After this change, Car17 would no longer be chosen on the basis of the eval-
uations in Table
2.4
. It would be replaced by Car16. The score of Car16 would be
0 * (0.08) + 1 * (1
0.08) = 0.92.

2.3.3 Pairwise Comparisons in the Space of Sets of Criteria
The strategy of pairwise comparisons of sets of criteria may be employed to
determine the capacity. This strategy becomes more feasible if it is not needed to
quantify the preference, but only to tell whether there is indifference between the
elements of the pair, and, otherwise, which one is preferred.
This simpli
cation in the comparison can be applied at the cost of complicating
the objects of comparison, the decision maker being called to compare not pairs of
criteria, but pairs of distributions of weights on the set of criteria. Under these
