The article shows the possibility of using a mathematical model of a bearing with various types of defects for machine learning of the vibration diagnostic system. A plane geometric model of a radial bearing with two degree of freedom is considered in detail, a system of differential equations describing the nature of the motion of moving masses in the mechanical bearing system is presented. A formula is obtained for calculating the total kinematic disturbance, the calculation of which is associated with significant computational costs. The article proposes an alternative calculation method, namely, modeling the profile of kinematic disturbances in the time domain, which will minimize computational costs. The adequacy of the proposed method is confirmed by calculations in Matlab and comparison with experimental data. The development of equipment maintenance systems for the actual technical condition is relevant as in the case of operation of facilities of increased danger Gerike, and in the case of the operation of expensive equipment Pisarev and Vaganov, where the diagnosis with disassembling the machine leads to large financial losses. Diagnostics of equipment by vibration parameters allows fixing defects in the early stages during normal operation without the need to disassemble the units and take them out of service.

The purpose of this study is to develop approaches to assessing the effectiveness of R&D of civilian use carried out within the framework of federal target programs based on integrated accounting of performance indicators and the cost of projects. Methods of comparative analysis as well as the methods of expert estimations were used. The developed methodology is tested on the example of the most knowledge-intensive program — the Federal Targeted Program “Research and development on priority directions of scientific and technological complex of Russia for 2014-2020” showing its practical applicability. It confirmed the hypothesis about the existence of significant differentiation of projects containing R&D according to the quantitative structure as well as scientific and technical potential of the established objects of intellectual property in comparison with the costs of R&D. The existing system for assessing the effectiveness of R&D conducted within the framework of targeted programs is carried out with aggregate output parameters and does not pay attention to the specific contribution of each project in improving the indicators of the entire program. The authors proposed to use the concepts of “weighted effectiveness” and “innovative efficiency” of projects. The quantitative evaluation of projects based on these parameters made it possible for us to perform the ranking of projects, to identify groups of projects with varying degrees of innovative efficiency, and to distribute the most effective, low efficiency and expensive projects according to thematic areas of research.

“…Set of factors may have effect on the productivity and efficiency of production, the structure of production and its technological level, intensity of work and non-productive expenses of working hours are taken into account [1,2,12,17,19,22,26]. As an analysis of these enterprises of GAS industrial Group shows, untapped opportunities of improvement of these indicators are closely connected with the systematical losses, which were revealed during use of the equipment.…”

The service and equipment repairing process is the necessary condition for the growth of production capacity of enterprises, and thereafter it predetermines the approach for organization of production and upbuilding of production streams. In the article different options of reduction of working hours loss are considered, due to equipment downtime elimination because of repair and equipment maintenance on the reason of the increased operation. Also, in the article reserves of growth of labour productivity and reductions of unit cost are identified. It is proved, that current equipment monitoring allows to eliminate different defects in rationing of operating time of the equipment, it also allows to reach the permanent production’s rhythms, to increase the monitoring level, to provide the timeliness delivery of materials and components. As the example, in the research was used factual material of planned measurement of technical condition of the equipment on a separate production of GAS Group, methods of monitoring of technical condition and productive equipment maintenance and standard criteria of the equipment’s condition were developed.
