| Description | A lot of methods for solving multiple criteria decision problems requires some weights of criteria. Widely used way of setting weights is based on pairwise comparisons, but there often occur inconsistencies in the preference expression. Saaty defined the consistency ratio for the analytic hierarchy process where the preferences are expressed in a multiplicative way. We propose a measure of inconsistency for additive preference matrix and carry out an empirical comparative study on the degree of inconsistency of the preference relation in both additive and multiplicative way. |
