Saaty’s Analytic Hierarchy Process (AHP) is a widely used and often considered tool in decision-making theory. This method allows to determine the classification of a set of multiple responses based on pairwise comparison of two answers. One of the main shortcomings of this method, in its original version, is the need to use a fixed set of numerical or linguistic descriptors. This requirement brings a lot of problems, especially for people who have never encountered this method before.In the proposed approach, the concept of using GUI tools to determine the preferences of respondents is developed. In this way, it allows conducting surveys among people who have no experience with AHP. In contrast to previous methods, in the proposed novel approach all possible combinations of responses are considered. The combinations of respondents’ answers are obtained in the process of projecting the choices indicated by the slider onto the classical descriptor space. The application of such a method fully takes into account the preferences of the respondents. The results of numerical experiments conducted among students confirm that this approach is very intuitive, and does not cause any difficulties for the respondents.
