The article is devoted to the description of the development of an algorithm for finding periodic solutions of one linear system of two coupled oscillators with a small parameter based on the Lyapunov-Schmidt method. The cases when the frequency of forced oscillations coincides with one of the natural oscillation frequencies are considered. Graphs of periodic solutions and phase trajectories of a system of two coupled oscillators have been constructed.

This article considers the process of creating an add-on software module for the Teamcenter industrial product lifecycle management system, which automates the process of creating the structure of the «Configuration Sheet» document. The authors describe the stages of modeling, design and implementation of this module.

The problem of optimizing the level of consumption for an economic object on the example of a specific enterprise is considered in the article. On the basis of the maximum principle, the problem of savings optimization is solved. The optimal trajectories of consumption and capital-labor ratio are obtained.

The first section of this article presents the basic definitions of the topic, the second chapter focuses on structurally stable circle transformations, and the last chapter is dedicated to suspensions on model transformation of 1. The basic results of the research are theorem 3.1 about equivalence of suspensions on model diffeomorphisms and statement 4.1 that equivalence of suspensions on orientation-reversing diffeomorphisms implies the diffeomorphisms conjugacy.

The article presents a software system prototype developed by the authors and designed for making collective decisions by remote voting based on blockchain technology. As a result, both open and secret voting have been implemented. The receipt of reporting documents based on voting results has been automated. It is also possible to generate minutes of meetings, extracts from minutes, etc.
