In today's world, health control is an essential element of everyday life. The article highlights the list of functional capabilities of various devices (smart watches, fitness bracelets) and describes the results of a formalized analysis of the functional completeness of health monitoring devices. On the example of two different sets of user requirements, two conditional systems are included in the study, by the degree of similarity with which it is possible to judge how the analyzed devices are suitable for this user.

The results of the analysis of the functional completeness of ten intelligent video Analytics systems are presented. It is shown how the video Analytics systems selected for comparison have similarities or differences in the criterion of functional completeness. The paper analyzes whether they contain the most typical video detectors and what additional video Analytics functions each of the compared systems has. It is shown how it is possible to estimate as far as functional completeness of this or that system corresponds to requirements of the user.

This article deals with the problem of determining the cost of renting real estate. The idea of minimizing the absolute error function using artificial neural networks is substantiated. Particular attention is paid to the process of determining the input data of the neural network. In particular, the problems of determining such parameters as the improvement of the region and premises. The article clarifies the features of determining the weight coefficients to determine the technical equipment of the room using a genetic algorithm. A model of neural network architecture is proposed. The model of change of weight coefficients is described. As a result, the model was tested on test data, and the model of data correction taking into account price dynamics was described.

This article presents a mathematical model of the distributed registry as a Queuing network. The main components of this network, as well as their formal representation are considered. The model of the peer-to-peer network is visualized, the vector of the network state is defined, and the restrictions of the state space are defined. After that, the laws of distribution of individual flows and service time were presented. In addition, the design elements of the infinitesimal matrix were determined. Based on the data obtained, a simulation model of this process was produced. For simulation, the Anylogic package was used. The results of simulation were analyzed and the most optimal parameters were selected.
