The Z-number concept is the attempt to model real-world uncertainty and relates to the issue of reliability of information, especially in the realms of economics and decision analysis. In this paper, we present an approach that can handle Z-numbers in the context of multi-criteria decision-making applying direct computations. In this paper we consider an Anаlytical Hierarchy Process based on Z-number valuations, taking into account the uncertаinty of the experts` opinion in estimаtion of the options. We considered a case of estimation of technical institutions with 7 criteria: campus infrastructure, faculty, students, academic ambience, teaching learning process, use of advance teaching aid, supplementary process and 3 alternatives: technical institutions.
