Abstract

In this paper we propose a decision-making method with paired comparisons, which calculates a ratio of evaluation values of alternatives with respect to a goal. If we have concrete evaluation values for each alternative with respect to criteria, the ratio calculated is the same as one with weighted summation method. In this paper we show the procedure of this method and its validity with mathematics. Furthermore, we propose a way to check validity of the final answer obtained with this method. We don’t discuss what kind of paired comparisons we should utilize, while we use paired comparisons in the Analytic Hierarchy Process (AHP) and the Analytic Network Process by T.L.Saaty in an example.
