The global criterion weights represent the relative importance of criteria. To define the
global criterion weights, several scenarios are developed by applying the pairwise
comparison approach (see Section 3.1.3). For the purpose of demonstrating the OWA
procedures, this case study focuses on one of the criterion weighting scenarios. Table 4-
2 shows the pairwise comparison matrix. The meaning of scores in the pairwise
comparison matrix is given in Table 3-2. The pairwise comparisons are normalized; that
is, each cell of the matrix is divided by its column total (the results are shown in Table 4-
3). Then the global criterion weights are obtained by computing the average value of the
normalized pairwise comparisons (see Table 4-3).
