Effectiveness Assessment

Currently, the use of aviation systems with unmanned aerial vehicles (UAVs) of various classes and special purposes has gained particular relevance and practical importance in the interests of both special customers and civilians. Modern UAVs are used both individually and as part of a group, they can carry several target loads on board simultaneously, they are built on various physical principles: a multifunctional optoelectronic system, a digital aerial system, an airborne radar station, a radio and electronic reconnaissance system, and a system communications for transmitting data from target loads (sensors) to a mobile device (for example, a tablet) to a remote subscriber, etc. However, the question of determining the effectiveness of solving both individual UAV targets and finding an integrated assessment of the effectiveness of using aviation complexes with UAVs when solving a set of targets (sequentially or sequentially-in parallel in time) taking into account their priority and a number of other factors. This article structurally consists of three parts. In the first part, we can observe a scientific and methodological approach to determining the effectiveness of solving particular communication targets and remote monitoring by a complex with UAVs according to the probability of their solution is developed. In the framework of this approach, a mathematical apparatus has been developed for the functional depend-ence of the probabilities of solving particular target problems with the design parameters of target loads as part of the UAV, taking into account the peculiarities of its functioning and under the conditions of existing limitations and assumptions. The scientific and methodological approach allows already at the stage of the formation of the tactical and technical task for the complex with UAVs to obtain, using the calculation method, quantitative estimates of the probabilities of solving particular targets taking into account the technical backlog of industrial enterprises for key components of the complex (target loads, communications equipment complex, etc.). The methodological apparatus developed in the article is universal and invariant with respect to input parameters, i.e., the number of tasks to be solved, the stages of operation of the complex with UAVs, and can be easily adapted to new conditions of use. It should be noted that the result of the article is the methodological apparatus for finding exactly the integral estimate. Finding performance assessments for the group use of UAVs, as well as taking into account possible countermeasures, is beyond the scope of this article and is a direction of further research on this topic.

Современные сложные радиотехнические комплексы и системы входят в состав ракетно-космических, авиационных, сухопутных, морских изделий, обеспечивающих решение задач повышения обороноспособности и безопасности РФ, а также отвечающих интересам гражданских потребителей. При этом на этапе проектирования радиотехнических комплексов и систем закладываются требуемые расчетные параметры по надежности, безопасности, долговечности, технологичности в целях обеспечения требуемого срока их эффективного функционирования для решения поставленных целевых задач. Рассмотрены результаты математического моделирования надежности проектируемых станций спутниковой связи на подвижных объектах (космические аппараты, беспилотные летательные аппараты, автомобили, железнодорожные поезда), которые отражают методический подход к определению надежности комплекса или системы верхнего уровня. Принципиальным моментом является возможность определения числовых значений данного показателя еще на этапе составления тактико-технических (технических) заданий на выполнение НИОКР, проведения аванпроекта, т.е. тех этапах работ, на которых цена ошибки не является существенной и имеется принципиальная возможность внести изменения в конструктивные и схемотехнические параметры разрабатываемых радиотехнических комплексов и систем Modern complex radio communication and systems are part of rocket-space, aviation, dry-track, marine products that provide the solution of tasks both to increase the defense and safety of the Russian Federation and meet the interests of civilian consumers. At the same time, at the stage of design of radio engineering complexes and systems, the required design parameters for reliability, safety, durability, technological and technical support are laid in order to ensure the required period of their effective functioning to solve the set target tasks. This article considers the results of mathematical modeling of reliability of projected satellite communication stations on mobile objects (spacecraft, unmanned aerial vehicles, cars, railway trains), which reflect the methodological approach to determine the reliability of the complex or upper-level system. A fundamental point is the possibility of determining the numerical values of this indicator even at the stage of compiling tactical and technical (technical) tasks for R&D, conducting an advance project, i.e. those stages of work at which the error price is not significant and there is a fundamental possibility to make changes to the design and schematic parameters of the developed radio systems and systems

Integral Assessment

Currently, the use of aviation systems with unmanned aerial vehicles (UAVs) of various classes and purpose for the benefit of both special customers and civilian purposes has acquired particular relevance and practical significance. Modern UAVs, used both separately and as part of the group, can carry several target loads on board at the same time, built on various physical principles: multifunctional optoelectronic system, digital aerial photography system, on-board radar station, radio and radio reconnaissance system, communication system for transmitting data from target loads (sensors) to a mobile device (for example, a tablet) to a remote subscriber, etc. At the same time, the issue of determining the evaluation of the effectiveness of solving both individual target tasks of UAVs and finding an integral assessment of the effectiveness of using aircraft systems with UAVs when solving a set of target tasks (sequentially or sequentially-in parallel in time), taking into account their priority and a number of other factors, remains practically unlit. The scientific and technical article consists structurally of three parts and is devoted to the consideration of the issues of finding an integral assessment of the effectiveness of the use of aviation systems with unmanned aerial vehicles. In the first part of article [1], a scientific and methodological approach has been developed to determine estimates of the effectiveness of solving private target problems of radio communication and remote monitoring (by optical and radar means) by a complex with UAVs. The second part of the article presents a mathematical apparatus for assessing the effectiveness of solving problems of conducting radio-technical reconnaissance and aircraft destruction of targets. As a criterion for the effectiveness of solving all private target problems, a universal indicator of the probability of solving them has been adopted, which will ultimately allow for convolution and determine an integral assessment of the effectiveness of solving a whole set of target problems. The methodological apparatus developed in the article is universal and invariant to the input parameters, that is, the number of solved target problems, the stage of operation of the complex with UAVs, and can be easily adapted to the new conditions for the use of other complexes with UAVs. Within the framework of this approach, a mathematical apparatus for functional dependence of probabilities of solving particular target problems with design parameters of target loads in the UAV has been developed, taking into account the peculiarities of its functioning and in the conditions of existing restrictions and assumptions. The scientific and methodological approach allows already at the stage of formation of the tactical and technical task for the complex with UAVs to obtain quantitative estimates of the probabilities of solving private target tasks using the technical backlog of industrial enterprises for key components from the complex (target loads, a set of communication facilities, etc.). Finding effectiveness estimates in the group application of UAVs, as well as taking into account possible electronic counteraction, goes beyond the scope of this article and is the direction of further research on this topic.

This paper has examined the influence of bearing design and operation in controlling lubricant supply to the contact zone. Grease lubricated contacts are liable to starvation and as a result the film thickness is reduced, this can result in surface damage or premature bearing failure. It is of obvious importance to know when starvation occurs and the effect of grease type, bearing design and operation on lubrication replenishment. The aim therefore is to develop a starvation parameter capable of predicting the operating limits for a particular bearing/grease system. A number of bearing design parameters are examined in the paper, these include cage design, ball spin and bearing size. Ball spin and cage effects can be efficient mechanisms for maintaining the lubricant supply to the track. Increased bearing size, line contact geometries and high load result in reduced lubricant replenishment of the contact. Using this analysis it will be possible to establish operating limits for families of bearings.

Subject. As digital technologies spread across all industries, active processes of digital transformation need to be managed both nationally and regionally. Assessing the extent of digitalization across types of economic activities is the key issue for setting up the socio-economic development strategy of the region and evaluating its efficiency. Objectives. The study is aimed to formulate and test methodological approaches to assessing the digitalization in types of economic activities and the potential of digital technologies for the real economy. Methods. The study relies upon the dialectical method, systems approach, questionnaires, expert approach, interpretation of empirical facts through tables, etc. Results. We devised a methodological approaches to assessing the extent of digitalization in types of economic activities across regions. The approach combines the quantification and evaluation of the process and helps determine the extent of local digital transformation at the regional level. We devised and tested the methodological approach to rating digital technologies, which have the high potential for raising the competitiveness and resilience to competition of the industrial sector in the Russian regions. As opposed to the existing approaches, the approach accounts for the current scale of digital technologies in the national economy, the potential for growth in the demand and supply in the domestic and foreign markets, and the potential for import substitution with respect to foreign technologies and products. Conclusions and Relevance. What makes the proposed methodological approaches more preferable is that they help assess not only the extent of digitalization in types of economic activities and the predominance of certain types in industrial enterprises, but also determine their potential for import substitution in terms of digital security.

Because bioeconomics is born of the interaction between the biological activity system and its socio-economic activity system, a holistic methodological approach is essential to study the relations between them. However, it must search for increasing levels of reductionism within each discipline to delve into the ultimate nature of each one of the intervening forces, whether economic or biological. This paper explores the economic forces. Through the biological capacity to comprehend, man and by extension, society, accumulates knowledge, the fulcrum from which he is able to dominate over his natural habitat. From this ‘point d’appui’, man builds two basic tools to assist him in achieving the goal of bettering his social condition. On the one hand, he creates institutions that allow him to “live with others” and, on the other, he develops technology that helps him to “live better with others”. Institutions, also referred to as ‘social technology’, tend toward stability over time while technology or ‘material technology’, tends toward instability, which would suggest that, normally, the mechanics of change will originate in material technology and, from there, progress to social technology by way of the political market. The level of progress and development attained depends on the quantity and rate of growth of knowledge applied by a society. In the process, man and his collectivity are forced to adopt new views of their environment through new shared mental models. The concurrence of equipment and political market will ultimately become the prime mover of institutional and economic change as well as change in mentality. Both technologies must keep on an adaptive course of stable evolution since discrepancies arising between them can cause tension between the various social groups. Adequate management of technological shock is essential to avoid extreme situations of social conflict. Herein lie the most important political decisions that a government must confront over the long term.

Innovation Cycle

The success of innovation activities of industrial enterprises to create product innovations depends on many factors. One of the main factors in this list is an objective assessment of their market prospects. This assessment can be carried out using the procedure of marketing testing, as it contains necessary methodological support and tools to determine the commercial prospects of product innovation at each stage of the innovation cycle. The effectiveness of marketing testing largely depends on how successfully organized this process in the enterprise, which actualizes the development of organizational and economic mechanism for managing marketing testing of market prospects for product innovations. This research is devoted to this question. The article presents the organizational and economic mechanism for managing marketing testing of market prospects of product innovations of industrial enterprises. The developed mechanism contains: subsystem of information support (internal and external information), target subsystem (tasks and purposes, criteria and principles of management of marketing testing), control subsystem (subjects which carry out management and functions which they carry out), the managed subsystem (divisions of the enterprise). Involved in marketing testing), providing a subsystem (methods and resources of management) and a subsystem of controlling the procedure of marketing testing of market prospects of product innovations. The mechanism also includes a subsystem of marketing testing, which consists of the author’s theoretical and methodological approaches to assessing the market prospects of product innovations at the stages of the innovation cycle of their development. It is based on the following approaches: theoretical and methodological approach to foresight research of future needs in product innovations; theoretical and methodological approach to the criterion base of evaluation and selection from a number of alternatives of innovative projects for the development of product innovations; theoretical and methodological approach to marketing testing and evaluation of market prospects of product innovations; theoretical and methodological approach to the diagnosis and strengthening of consumer capital of the enterprise; methodical approach, by which decisions are made on the readiness of product innovations to enter the market and complete the work on the procedure of marketing testing. The marketing testing mechanism contains the relationships between the subsystems (influence, coordination, and adjustment, feedback) to obtain an overall result. The result of the implementation of the proposed mechanism is tested for market success, developed product innovation, which is ready for commercialization, which is predicted to succeed, and the developer, thus, will receive all planned revenues and profits from its sale on the market. The conducted analysis is a future basis for the implementation of the developed organizational and economic testing mechanism in the practical activities of domestic innovative industrial enterprises.

Current processes of environmental law enforcement require the use of innovative approaches to the problem of environmental management. In this regard, an adequate choice of the environmental performance indicators of an enterprise and the technique for their analysis, aimed at developing efficient, environmentally friendly management decisions, is of great importance. The technique for calculating the environmental and eco-economic performance indicators of a coal mining enterprise, including using the weighted average hazard class of pollutants or production and consumption waste is discussed in the article. Various options for the application of this approach, which is of practical importance for reducing the labor intensity of management decision-making by industrial enterprises, are considered.
