Abstract <p>An approach to improving the structural consistency is considered. The purpose of the study is to select a method for combining identical objects into groups, since it is identical objects that can effectively exchange information and use the information obtained as a result of this exchange. To achieve this goal, a number of experiments with different methods were conducted, after which the best one was selected in terms of the target quality measure and latency. The proposed approach allows taking into account various characteristics of objects and the relationships between them. This ensures accurate determination of identical objects. The proposed approach also has an efficient implementation for distributed computing systems. This makes it fast even on large amounts of data. The comparison of the approaches under consideration is made using the example of the problem of searching for identical products for managing assortment and supplies.</p>
