The paper analyzes three key indicators of economic growth and life quality from the National Development Goals of the Russian Federation. The following equivalents of these indicators were identified to form regions into clusters and highlight the main trends in their development: the growth rate of gross regional product (GRP), life expectancy, and poverty level. We studied the nationwide data based on the indicators, analyzed the distribution of regions, and carried out a cluster analysis according to 2017-2019 data. Our results suggest expanding the list of the Russian Federation subjects that require additional support in their development. More than one-third of the regions of the Russian Federation have been developing at a rate of less than one percent per year in the last three years. Considering the consequences of the pandemic, it can lead to serious problems in achieving the declared growth rates. Plans to increase life expectancy have already been adjusted. Considering the little-studied consequences of coronavirus infection, additional measures in the medical field will be required. The level of poverty of the population also demonstrates a significant degree of differentiation of the Russian Federation regions.
In the world and domestic practices of technical maintenance and repair (TMR) of locomotives there exists a tendency for the expanded use of technical diagnostics systems, the transition to predictive repair to reduce the costs of their life cycle. Modern hardware and software tools make it possible to create automated technical diagnostics systems (ATDS) for all types of locomotive equipment but equipping service repair locomotive depots with them requires significant capital costs with an unacceptably long payback period. The objective of the work is to develop a method and a corresponding simulation modelling software program to determine technical and economic feasibility of using certain means of technical diagnostics.Diagnostic systems reduce waiting time for repairs, the volume and cost of scheduled and unscheduled TMR, which makes it possible to reduce the operating fleet of locomotives.In modern economic calculations, to assess the success of an investment project, the indicator «Net present value (NPV)» of the project is used. Based on this principle, in relation to ATDS, a method for determining feasibility of introducing various types of ATDS and the corresponding methodology and software made with the algorithmic language VBA (Visual BASIC for Applications) in the MS Excel environment has been developed.The work carried out simulation modelling for Russian conditions of the payback of main types of diagnostic systems comprising on-board based microprocessor control systems, rheostat testing stations for diesel locomotives, diagnostics of traction motors, etc. The economic feasibility of introducing these systems has been proved. Also, economically inexpedient diagnostic systems have been identified, f o r example, automatic measurement of the profile of a wheel set tire.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
