Abstract
The dominant alternatives method by Kinoshita and Nakanishi (1997) is a new type of AHP-Analytic Hierarchy Process-designed to deal with the case in which the weights of criteria vary in accordance with the alternative chosen as the dominant viewpoint. This study clarifies differences between the general viewpoint and the dominant viewpoint, and features of the relative and the absolute measurements under both views. When conducting continuous surveys, additional data from the latest survey have to be reflected into the result of the previous survey in a certain scheme. This paper proposes "concurrent convergence" as a processing technique for additional data in an application of the dominant alternative method. When there are more than one dominant alternative, the technique requires a convergent calculation toward the coincidence among derived weights of criteria on each alternative. By adopting the convergent values in the overall evaluations, every evaluation value on every alternative will be equal. This technique, therefore, enables us to reserve the essential features of the dominant alternative method.
