โœฆ Synopsis

The least-squares priority method is an e ective priority method in the analytic hierarchy process. But it is not appropriate under fuzziness. This paper is concerned with the question of estimation of weights of factors by least squares from a fuzzy judgment matrix. First, the expression form of least squares under fuzziness is given. Then the associated system of equation is developed. After some properties of the system are investigated, the explicit solution is derived. Finally, it is shown that the solution of the system is the solution of the fuzzy least-squares. In this paper, an example is also given to illustrate the procedure.

Counter-examples are given to show that in decision making, different methods of deriving priority vectors may be close for every single pairwise comparison matrix, yet they can lead to different overall rankings. When the judgments are inconsistent, their transitivity affects the final outcome, and
