The Impact

Today digitalization increasingly affects the economy, including the transport industry. The consequence of this is the emergence of digital twins that allow modeling and predicting the behavior of both individual processes and enterprises as a whole.The aim of the article is to investigate the process of digitalization in the transport industry. The theoretical basis of the article was the universal organizational science of A. Bogdanov.The article offers a definition of information, and its classification in relation to the economy at three levels: applied information (technological information), information about algorithms of the owners of factors production behavior (behavioral information) and information, with which the impact on the owners of production factors and the real economy in general (directive information). The totality of these levels of information from the macroeconomic point of view forms an information economy, and from the microeconomic point of view – a digital twin of a particular subject of the real economy.It is proved that the digital economy is a subsystem of the information economy, differs in a binary way of presenting information and is maximally oriented to the management of the real economy.Information precedes all activity, so the real economy is a product of the information economy. Consequently, the technological division of labor is based on a prior informational division of labor. This theoretically allows us to judge the adequacy of the digital twin through the analysis of individual technological levels of the transport enterprise. This hypothesis was applied to the analysis of the Russian railway transport, which gave reason to consider this approach promising for use at macro- and micro-levels both.

The Impact

There is currently a discussion going on in the scientific community about using digital twins and modeling to manage risks in the supply chains. This need for constructing digital twins is caused by the low reliability and stability of supply chains due to the faults in their operation. These faults are a result of risks in the supply chains which can be consolidated into two types. The first type is operational risks. These are the current risks of the supply chain itself caused by an uncer-tainty of supply and demand as well as by an obstructed flow of information along the supply chain. The second type is critical risks caused by force majeure. These risks disrupt the normal operation of the supply chain and critically reduce the most important performance indicators of the company such as annual income and profits. Risks happen due to natural or man-made causes such as fires and floods in the distribution centers or at production facilities, legal disputes with sup-pliers, strikes, terrorist attacks on logistics facilities and others. Dynamic simulation and analytical optimization are two dominant technologies for managing risks of the supply chains, which helps to increase their reliability and stability if failures occur. Through optimizing and simulating of the supply chains, companies can generate new information about the impact of failure and influence the supply chain and its performance by looking at various scenarios that simulate the locations of failures, the duration and recovery policies. An analysis of the literary sources shows that there is no single approach to build the concept for a supply chain digital twin. This article gives an overview of the literature according to this problem and offers the author's point of view on the concept for a supply chain digital twin.

Engine operating cost is a major contributor to the direct operating cost of aircraft. Therefore, the minimization of engine operating cost per flight-hour is a key aspect for airlines to operate successfully under challenging market conditions. The interaction between maintenance cost, operating cost, asset value, lease and replacement cost describes the area of conflict in which engine fleets can be optimized. State-of-the-art fleet management is based on advanced diagnostic and prognostic methods on engine and component level to provide optimized long-term removal and work-scoping forecasts on fleet level based on the individual operation. The key element of these methods is a digital twin of the active engines consisting of multilevel models of the engine and its components. This digital twin can be used to support deterioration and failure analysis, predict life consumption of critical parts and relate the specific operation of a customer to the real and expected condition of the engines on-wing and at induction to the shop. The fleet management data is constantly updated based on operational data sent from the engines as well as line maintenance and shop data. The approach is illustrated along the real application on the CFM56-5C, a mature commercial two-spool high bypass engine installed on the Airbus A340-300. It can be shown, that the new methodology results in major improvements on the considered fleets.

The research paper addresses the issue of the impact of MMORPGs on social culture and communication skills of individuals. The mainstream discourse about computer games which take individuals away from reality and substitute the real life by the fictional one is complemented by brand new ideas, which affirm that computer games do not substitute but supplement the real life and expand its possibilities. To confirm the presented point of view we use diagnostic questionnaire of interpersonal relations by A.A. Rukavishnikov. This questionnaire is aimed to evaluate typical ways of respondent’s attitude towards other people. At this point we have 43 gamers and 29 non-gamers involved in our research, aged 18 to 57. The comparison of a user and non-user answers gives a bigger view on an overall gaming experience. In the obtained indices we note that there are no fundamental differences between MMORPGs gamers and ordinary people. During research, MMORPGs users have showed many important social interaction skills such as striving to control own actions, collaborate with others, though with a low interest in emotionally charged relationships. Authors discuss the idea about the differences between addiction and fascination among gamers.

The Impact

Abstract We examine the Indian bank asset quality review, which doubled the declared loan delinquency rate. Relative economic stability during the exercise and the absence of a capital backstop together make it unique. We find that the expected reduction in information asymmetry does not automatically lead to the recapitalization of banks by markets. The consequent undercapitalization leads to underinvestment and risk-shifting through zombie lending. The impact flows to the real economy through borrowers, including shadow banks, and adversely impacts growth. These findings show that bank cleanup exercises not accompanied by policies aimed at recapitalization may be insufficient even during normal times.

In this paper the potential impact of digital transformation in general and digital twin applications on the Product Management Process (PMP) in particular will be investigated. The object is to figure out the potential benefits of digital twin utilization. Methodologically, a conceptual and analytical approach are applied in using statistical data, surveys, latest literature and logical conclusions. Thus, the approach is twofold: from the conceptual point of view the different types of digital twins are introduced; from the analytical point of view different applications in different stages of the PMP will be subject to investigation. So, this paper can be categorized as conceptual paper based on an extensive literature research. The findings of research revealed that the digital transformation can offer various benefits for the PMP. It can be summarized that in all phases of the PMP potential benefits can be identified. The most important is saving time and money, avoiding waste of physical resources and simultaneously raising quality, reliability and competitive advantage. Regarding the originality value it can be stated that this is the first comprehensive examination of the entire PMP with regard to digital transformation in order to identify sources of potential benefits.

The Impact

The purpose of this publication is to study the system of economic security parameters and improve the process of using RADAR logic as an element of assessing the information security of the enterprise. The importance of the concept of economic security of enterprises (EBP) is that scientists recognize it as an important factor in national security, since the real economy is an environment of planning, organization and the best use of resources. Four main factors of EBP are considered: a) planning; b) monitoring of the external and internal environment; (b) identifying and implementing threat response measures; d) control and improvement of the system. Taking into account the turbulence of the external environment, the impact on the formation of parameters of the EBP of macro-, meso- and microeconomic level factors is investigated. It is proposed to lay the methodology based on the model of the European Quality Management Fund (EFQM) as the basis for the formation of the EBP culture. Its goal is to achieve a high level of business excellence, the direction is to promote the processes of coordination of business and security goals, coordination of efforts to achieve sustainable security indicators, the formation of market knowledge and best practices for their exchange. The prospects for practical use of the EFQM model, the components of which are: basic concepts of perfection are carefully studied; criteria; RADAR logic. The conclusion about the feasibility of implementing the RADAR system is substantiated. Full and comprehensive implementation of the system can have a positive impact on the level of short-term liquidity of the company's assets, its long-term solvency, the formation of the desired level of profitability for shareholders, and generate positive external effects for society and the environment. The complexity of ensuring the EBP is explained by the variety of manifestations and relationships of interactive elements among the internal components of enterprises and the unpredictability of the manifestation of external factors. A logical conclusion is drawn about the importance of the EBP concept, its ability to include a significant number of factors in the sphere of management influence. The direct consequences of using the EBP concept are the comprehensive provision of both its own economic security and the fundamental principles of its organization, the safety of the activities of individuals, the ability to take into account numerous factors in the formation of the actual level of regional, national and international economic security of the state. The strategic directions of further research are outlined: study, schematization, numerical formalization of system-structural relations of components and threats to economic security of enterprises, the real sector and the national economy as a whole.

Educational Component

The purpose of the current study is to analyze the impact of higher education and universities on the dynamics of the digital economy. The authors hypothesized to distinguish three components (educational, research, innovation) in the digital economy development. Within this article, the results of using index and cluster analysis methods to determine the impact of the educational component on the processes of digital economy development in Ukraine at the macroeconomic and meso-economic levels are presented. The special attention is put on the educational component because the higher educational institutions concentrate intellectual capital of the country, as well as prepare future specialists for the needs of digital economy. Moreover the universities’ scientists make an impact on digital economy development by conducting research and transferring their results technological innovations, information and communicational technologies, etc.) into the real economy. During the research, main problems of digital economy development, determined by the poor quality of educational services, insufficient commercialization of university research results in the real economy, are identified. The authors conclude that solving the identified problems requires synchronization of interests and establishing a long-term partnership between universities, business, the state and the public. Importance of optimizing the state regulatory influence on economic entities in the context of digitalization of the national economy is emphasized. In particular, it is proposed to group the set of measures of state regulation into three vectors, namely: neutral-encouraging (support of positive dynamics of intensive development), incentive-providing (resource and information support of development processes) and initiative-mentoring (motivation and coordination of development processes).

There are so many speeches delivered by such famous people in this world. But, if we are asked to give the point of view about the impact of each speech delivered then the speech from Martin Luther King Jr. will convey the high meaning in term of rethorical speech especially the content and the context about the concepts of repetition found. The speech was on 28th of August 1963, at the Lincoln Memorial, Washington D.C in a verbal ways and its text become the secondary data to be analyzed with much focus on emphasizing phrases, words or sentences. By using the concept of rethoric perspective through repetition such as anaphora, epistrophe and epizeuzis, the researcher wants to know the values behind the repetition. That is why, the analysis is using the descriptive qualitative research on taking the secondary data that has been adapted from the video and the text of the speech itself. The conclusion especially on the ideas of repetition are that Martin Luther King Jr. tries to make sure his audiences about that 1) the repetition is something more that the meaning itself, it is above. 2) The struggle, it is something true, needs to be realized in the real life, and adds the weight of the expection to be equal and free.

Since its inception in the late 2000s, blockchain has emerged as a powerful tool for creating trust without intermediaries to incentivize global communities for working for a common goal, such as the improvement of its very ecosystem, its applications and community adoption. While first blockchains were mainly devised for confirming transactions of their innate cryptocurrencies like Bitcoin, smart-contract blockchains like Ethereum can interface with the real-world through so-called “oracles”, which feed trustful off-chain information. This paper introduces digital twins of physical objects and processes as computational oracles to effectively unleash the tremendous opportunity offered by blockchain to the realm of fundamental science, research and technology development (RTD). The crowdsourcing concept is illustrated with the example of centrifugal flow control in microfluidic “Lab-on-a-Disc” (LoaD) systems.
