Problems of Managing a Cyber-Physical System in the Presence of Malfunctions in It
摘要
The study of various properties of information-technical systems from the point of view of interaction of their physical and digital components is a new and actual direction of modern science of cyber-physical systems. When considering modern cyber-physical systems, various authors recommend considering them as complex systems within the framework of system analysis. Due to the complexity of systems, adaptive algorithms should be relied upon in human-machine interaction. In this case, the specialist is seen as a decision maker. In the course of his work, he will strive to ensure the required mode of functioning of the cyber-physical system, including in the presence of faults in it. This paper proposes to consider the possible actions of a specialist in a cyber-physical system from the perspective of a simulation experiment. The paper provides an illustration of an algorithm scheme related to adaptive resource selection in a cyber-physical system. The scheme of rational decision making when resources are selected is shown. A methodology for generating logic models is proposed. The paper shows how game modeling can be applied to cyber-physical systems. The results obtained in this paper can be applied to a wide range of cyberphysical systems.

Database Deployment Pattern for High Availability
摘要
Ubiquitous digitalization and the development of big data technologies require a high level of availability (24/7) of information resources. Ensuring high availability of the database requires a significant amount of work on the design, testing and maintenance of several components and configurations. High availability can be achieved or maximized for the following deployment options: one database instance (with or without read replicas) and several main ones (with or without a coordinator). High availability ensures the smooth operation of the system by eliminating individual points of failure, while disaster recovery focuses on restoring normal operation after a failure or downtime. There are several deployment options because there is no universal solution. Choosing the best option depends on your specific use case and requirements. This article presents the main concepts of ensuring high availability and the most effective patterns for providing highly accessible database deployments.

Practical Aspects of Assessing the Economic Security of a Transport Company
摘要
Transport is an important sector of the country’s economy. Its activities have an impact on other businesses and the public. It is important that enterprises in the transport industry achieve a state of economic security. The absence of a unified definition of the concept of “economic security” and approaches to its assessment is shown. It is noted that the concept of “financial security” is closely related to the concept of “economic security.” It has been shown that without financial security, it is impossible to achieve a state of economic security. On the example of the most important enterprise of railway transport in Russia, an assessment of the financial condition, financial security and economic security was carried out. Extremely low economic security of the enterprise was revealed. Based on the analysis, some ways have been proposed to improve the financial and economic security of the enterprise in question.
The goal is to consider practical aspects of the economic security of the transport company through an assessment of the financial and economic security of FPK JSC.
Method or methodology of work: the study used a systematic approach and general scientific methods - statistical, comparative analysis, expert assessments and logical generalizations.
Results: shows the relationship between the financial and economic security of the enterprise. The economic security of FPK JSC was assessed as extremely low. Some ways to strengthen financial and economic security have been proposed.
Field of application of the results: it is advisable to apply the obtained results to economic entities engaged in activities in the field of transport.

Prospects and Possibilities Blockchain Technology Application in Logistics
摘要
The article discusses the problems and prospects for development of the logistics sector in Russia. The concept of blockchain, its main functions and tasks are described. The principles of operation of the system and examples of companies already using this technology are given. Now, in Russia, logistics support for cargo delivery has low quality and economic efficiency indicators. Logistics is in search of new technologies that will simplify and automate the process of accumulating and using data related to document flow, cargo tracking and information storage. Logistics chains can include dozens of links; the more nodes in the chain, the more difficult it is to control them and the more information appears. At the same time, interactions between producers, carriers and consumers are becoming less transparent. Blockchain technologies can solve these problems by reducing the cost of transportation, making information impossible to hack and falsify, and optimizing processing and query times.
Purpose: to consider the main problems and challenges arising in the field of logistics that blockchain technologies can solve.
Results: obtaining information on how blockchain technology can be applied in logistics, as well as identifying opportunities and prospects for its use.
Practical implications: deciding on the implementation of blockchain technology in logistics operations and using its advantages to assess efficiency and competitiveness.

Modeling of oscillations of the center of mass of a tractor with a tracked propulsion unit
摘要
To increase the traction force of tractors while simultaneously reducing the specific pressure on the soil, one of the effective ways is the use of a tracked propulsion unit. The article considers a variant of a tracked propulsion unit, installed separately on each drive axle of the tractor instead of wheels. The basis of the developed design of the tracked propulsion unit is the trackbed, which reduces the pressure on the ground and increases adhesion to the soil.
The results of simulation modeling of the rectilinear movement of a tractor with a tracked propulsion unit along grain stubble are presented. Realizations of oscillations of the front, sprung and rear, unsprung axles and the tractor frame were obtained. Oscillations in the ordinates of the reference surface were modeled as a random process with specified values corresponding to the reference surface of the grain stubble.
The simulation results showed acceptable oscillation values of the tractor frame with the proposed propulsion design. The proposed propulsion unit can be easily installed on a tractor instead of wheels and, if necessary, can also be easily dismantled.
Purpose. Investigation of oscillations of the center of mass of a tractor with a tracked propulsion unit using simulation modeling in the MATLAB Simulink environment.
Methodology. Methods of mathematical modeling and analysis were used in the article.
Results. The parameters showing the effectiveness of using a tracked propulsion unit instead of wheels on a tractor of traction class 6 are obtained.
Practical implications. The results obtained can be applied in the design of tractors to determine the acceptable parameters of the tracked propulsion unit.
