Table 1 Properties measurement table
Value range | Definition |
|---|---|
\(\tilde{a}_{ij} = 1\) | Elements i and j are of the same importance to the previous factor |
\(\tilde{a}_{ij} = 3\) | Element i is slightly more important than element j |
\(\tilde{a}_{ij} = 5\) | Element i is more important than element j |
\(\tilde{a}_{ij} = 7\) | Element i is considerably more important than element j |
\(\tilde{a}_{ij} = 9\) | Element i is extremely more important than element j |
\(\tilde{a}_{ij} = 2n\), n = 1, 2, 3, 4 | Importance of elements i and j is between \(\tilde{a}_{ij}\) = 2n − 1 and \(\tilde{a}_{ij}\) = 2n + 1 |
\(\tilde{a}_{ji} = 1/\tilde{a}_{ij}\) | Importance of elements i and j is opposite to that of elements \(\tilde{a}_{ij}\), respectively |
