Since the additive index of the general consistency of criteria (3.4) is equal to
0.705, it is possible to draw a conclusion that all examiners considered are
competent.
Let us calculate indexes of pairwise similarity (3.2) of examiners' criteria.
Results of evaluations are summarized in Table 3.2.

Based on the computed indexes of pairwise similarity of examiners' criteria, let
us construct a fuzzy binary relation of similarity. Elements of the relation matrix
are provided in Table 3.3.
