In the this paper there is a description of the methodology of constructing highly adequate models of materials which are produced additively. The paper consists of introduction to the problem, demonstration of each step of the methodology and conclusions about the method and its applicability. The developed approach is presented on the two additively manufactured metal alloys. The modeling process is based on the orthotropic model of elasto-plastic material behavior. The list of material properties to be found was formulated according to proposed material model. These properties were found from several mechanical experiments. The developed mathematical models of the material studied were checked for compliance to experimental data with use of finite element simulations. Finite element modeling of a complicated 3d-printed lattice structure was performed and compared with the results of natural testing. In order to study the correlation between the material properties and manufacturing process the analysis of microstructure was done.

At the present stage, the Russian Federation is at a fundamentally new stage of socio-economic development, a clear manifestation of which is expressed in the growth of economic recovery indicators, an increase in investment potential, a reorientation to domestic producers and domestic products. In this connection, the tourism sector can act as a serious tool for the socio-economic development of the Russian Federation. Tourism has a significant impact on ensuring sustainable socioeconomic development. Tourism, developing at a rapid pace, contributes to the development of related industries. The development of the tourism sector should proceed along the path of sustainable development of the constituent entities of the Russian Federation, and is aimed at removing infrastructural restrictions for the full use of the potential of the territories of Russia. In order to identify internal unused natural reserves, preserving the uniqueness and ensuring the environmental safety of the territories of advanced development. In this connection, it is advisable to use the cluster approach to clearly define the strategic territories for the development of the tourism sector. A “tourist cluster” is a collection of enterprises assembled into a single, logically structured system. They provide development, production, promotion of a tourist product. At the same time, one of the main guidelines for the development of the tourism sector is the provision of world quality standards.

The article deals with the issues of national aggregated ranking (NAR) of higher education institutions. This case is formulated as a collective choice problem. It is proposed to use voting procedures in small groups that meet the Condorcet principle as aggregation method. The paper applies collective choice rules to the problem under consideration. The alternatives final ordering stability obtained from the Board, Copeland, and Kemeny procedures is illustrated by specific examples. The empirical average was considered as Kemeny median approximate estimate. The example showed Board procedure instability to a slight change in the initial ratings obtained in the rating mechanisms under consideration. Using the voting procedures results described in the paper in small groups on a limited sample containing data from fifteen elements group are presented. The constructed three aggregated rankings proximity degree was estimated using two metricsthe Kendall rank correlation coefficient and the Kemeny distance. Based on a comparative results analysis, it can be concluded that it is appropriate to use collective selection procedures that are well-off in Condorcet when constructing aggregated rating of various organizations, including educational institutions.
