(.): In the tasks of multi-criteria evaluation and selection of objects with a multi-level structure, analytical aggregation mechanisms are mainly used, which are represented in the form of expressions (formulas) depending on the values of the end criteria of the hierarchical tree. One of the analytical mechanisms is the additive aggregation mechanism, when analytical expressions with an integral aggregation mechanism are set as the sum of object ratings according to the end criteria of a hierarchical tree with or without global quantitative weights. Recently, reference and production aggregation mechanisms have become widespread. In the reference mechanisms, aggregation is carried out by defining these objects as point values of features or areas of the feature space and recognizing the proximity or belonging of objects to them. This article discusses a method for evaluating objects relative to ideal reference profiles and a method for classifying objects according to reference profiles that does not require setting a proximity threshold. A procedure is proposed for the transition from the initial estimates presented according to criteria in different scales to the resulting quantitative and ordinal scale. A statement is made about the preservation of orderings between objects from different classes of proximity to reference profiles and those obtained by the additive aggregation method.
