Application of the analytic hierarchy process in a comparative analysis of automated information systems
In a scientific study, we investigated decision-making methods, in particular, the methods of expert estimations to solve problems. Reflected the possibility of using the analytic hierarchy process for researching and selection of information systems in accordance with the requirements of the customer. Comparative analysis has been performed on the example of automated library information systems

We investigate the microstructure and microhardness of high-nitrogen austenitic steel Fe-20Cr-20Mn-2.6V-0.3C-0.8N (in wt. %) after upset and high-pressure torsion (HPT) (6GPa) for ?, ?, and 1 revolutions at room temperature. As the result of deformation, steel microhardness increases by 1.5 times after HPT. Slip, twinning, formation of localized deformation microbands, and precipitation hardening are the main deformation mechanisms under HPT, and the level of solid solution strengthening of steel remains high after deformation

Modelling of factors' influence on technical efficiency of enterprises according to their form of ownership
This paper is dedicated to the research of Russian enterprises' productivity according to their form of ownership: Russian (RO), Foreign (FO) and Join (JO). We investigated the financial and economic indicators for 386 Russian enterprises, which produce machines and equipment in conditions of unstable economy (2012-2016). We utilized DEA method, which classifies object as effective if it has the biggest output with the smallest inputs, for evaluation of enterprises' technical efficiency (TE). Afterwards, dependencies between TE performance and main economic indicators were highlighted. Hence, based on these detected dependencies, we gave recommendation for improving technical efficiency of enterprises for each type of ownership
