A heated discussion has arisen over the “best” priorities derivation method. Using a
Monte Carlo simulation this article compares and evaluates the solutions of four
AHP ratio scaling methods: the right eigenvalue method, the left eigenvalue method,
the geometric mean and the mean of normalized values. Matrices with different dimensions
and degree of impurities are randomly constructed. We observe a high
level of agreement between the different scaling techniques. The number of ranking
contradictions increases with the dimension of the matrix and the inconsistencies.
However these contradictions affect only close priorities.
