The article explores the methodology of complex analysis of ways effective management of production systems. A generalized approach to the decomposition of modern digital systems based on physical control actions, signal transmission ways and generalized principles of control system construction is investigated. Additional control physical effects act as one of the target factors of intensification. A generalized formulation of the problem of optimal control of complex multistage processes is proposed, considering the main perturbing processes and a piecewise-constant functions of the local tasks. Methods of search of new technical solutions by means of the morphological analysis as the tool of systemic and cybernetic approaches in scientific research are proved. Intensification of control systems is aimed at increasing their economic efficiency as a result on search for technological resources, of purposeful influence traffic flows and so on. The formulated principles of hierarchy, selectivity, openness, and mutual consistency, which are not exhaustive, but are closely interrelated and determine the application of methods of hierarchically interconnected control, considering the intensification of systems when choosing the control factors, as well as of physical impacts. The proposed approach leads to the possibility of intensification of high-tech industrial production processes and transport systems, and so can be implemented in the process of their technical operation. Identification of possible physical effects, synchronization of signals is a key factor in using the proposed methodology. The modular system of transport companies allows for flexible and transparent management of the system as a set of individual elements. Generalized goal-oriented models are applicable in many branches of industrial production, including the intensification of transport systems and business processes of enterprises.

The paper presents a methodology for assessing the probability of communication disruptions in one beam of a radio communication system operating on the technology of space-time coding of signals. Expressions are given for an accurate and for an approximate estimate of the probability of communication disruptions in radio channels with multipath and signal fading. Long-term experimental studies of signal fading on a long-range tropospheric radio link have been carried out. It has been experimentally proven that the Rayleigh description of interference fading in multipath propagation of signals is observed in 60% of the time of communication sessions. For the rest of the communication sessions, other laws of probability distribution are observed. It is confirmed that they, together with Rayleigh's description of fading, are special cases of the four-parameter law of probability distribution. Convenient for practical use formulas are obtained for estimating the noise immunity of a communication channel. The graphs of the dependence of the probability of communication failure on the ratio of the average received signal power and the threshold level of the receiver signal are given. © 2021 IEEE.

signals properties comparative analysis is carried out for ultra-wideband pulse radar probing signals, which have equal spatial resolution and duration, but differ by presence or absence of high frequency filling. The broadband factor is used, defined as the relation of the probing signal bandwidth to its spectrum average frequency. Signal-to-noise and signal-to-passive interference ratios dependences on the broadband coefficient are obtained. It is shown that for the same antenna system aperture, dimensions and radiation power, the signal-to-noise ratio in a radar with a radio-pulse probing signal will be higher. That benefit is inversely proportional to the broadband factor square. Assuming that the passive interference level is proportional to the selection element area, its estimation is obtained. It is shown that when the spectral bands of ultrashort video and radio pulse probing signals are equal, the pulse with high-frequency filling has an advantage, in terms of the considered parameters. © 2021 IEEE.

Due to the peculiarities of the physical level of 5G NR (Fifth Generation New Radio) systems, nonlinear distortion of the amplifying path is one of the main negative affecting on the signal. Existing mathematical models of amplifier nonlinearities in the context of their application in the simulation of fifth-generation signals require adaptation. The work proposes the coefficients for nonlinear distortion of power amplifiers for Saleh and Ghorbani models. Based on the simulation model developed in MA TLAB, the spectral characteristics of the simulated processes of nonlinear distortion, amplitude-amplitude and amplitude-phase distortions, as well as the effect of nonlinearity on the noise immunity of the system (the dependence of the bit error rate (BER) from the signal-to-noise ratio (SNR)) for the 5G NR signal of the second numerology (200 MHz signal bandwidth) for all types of modulation supported by the standard on sub carrier frequencies (QPSK, 16QAM, 64QAM, 256QAM) are studied. © 2021 IEEE.

This article discusses the problem of implementing the Data Fabric architecture as a technology for sustainable data processing and storage for the modernization of industrial platforms in transport and road systems. To perform complex tasks like monitoring road transport facilities entails huge resources for storing interactive data online. The concept of transport enterprises moving to cloud systems opens up gaps in data management in hybrid and multi-cloud systems. To solve such problems, the implementation of the Data Fabric structure allows you to integrate data and metadata for use on various platforms. The sustainable development of such platforms is facilitated by the use of the Data Fabric mechanism as a built-in system for standardization and coding, the implementation of semantic compatibility, proprietary knowledge graphs and the domain of data values of the transport industry. Data Fabric helps organizations solve complex data problems and use cases by managing their data regardless of application types, platforms, and storage locations, while ensuring seamless data access and sharing in a distributed data environment. The article analyzes the stability of the Data Fabric platform as a domain-oriented decomposition model based on a distributed data architecture with centralized management, but not as a fragmented data warehouse. Using the example of such a decomposition, it is necessary to model an architecture that organizes analytical and other data by areas. In this architecture, the domain's interface with the rest of the organization includes not only operational capabilities, but also access to the analytical data that the domain serves to scale the system.

Current trends in the design of road systems are driven by the digitalization process. Work on the introduction of intelligent transport systems is being carried out all over the world, because the improvement of the road network is an important element in creating comfortable conditions for the movement of people in an urbanized environment; a tool for improving road safety. Based on interdisciplinary research methods in the framework of urban planning, the paper proposes a methodology for assessing the prospects for the development of an intelligent city transport system within the framework of the concept of participatory design. The formation of the transport system is seen as a process of coordination of institutional and civil needs. The goal of the joint work of urban planners and civil society is to improve the safety of road infrastructure, not only through the development and implementation of quality standards, but also through the internalization (recognition) of the value of new technologies by the society. It is necessary to introduce the principles of participatory design of the transport system into the development of the road network, the urban space should remain free for co-creation. The problem of the study is that technologies for improving road safety, including the use of artificial intelligence, automation systems for traffic management processes depending on the rhythm of the city, weather conditions, time of day (traffic flow detectors, CCTV cameras, "smart traffic lights", weather stations, vehicle traffic sensors, navigation information systems, weather information display systems, environmental pollution sensors, traffic control centers, etc.) can be perceived by citizens primarily as devices that restrict freedom of movement, and not as means of improving road safety

The model of distributed power amplifier, built on field-effect transistors of model MRF 9045, is presented. AM -AM characteristic and AM - PM characteristic investigated on the basis of this amplifier circuit are presented. The construction of a distributed power amplifier circuit for simplified modeling of parametric nonlinear distortion is discussed. Simplified models of this type of amplifiers for the HF and UHF ranges are given. In a simplified model for the HF range, the parametric capacitances are built on the basis of the capacitance-voltage characteristics on the field-effect transistor of model BLF 278. In the simplified model for the UHF range, the parametric capacitances are built on the basis of the capacitance-voltage characteristics on the field-effect transistor of model MRF 9045. The features of constructing a simplified model of a distributed gain amplifier are discussed. On the basis of simplified models of parametric nonlinear distortion amplifiers, several cases of the influence of parametric capacitances are investigated such as: the influence of the input parametric capacitance, as well as the influence of the output parametric capacitance. The result of the research is the amplitude and phase-amplitude characteristics. The reasons for parametric nonlinear distortions and methods of their linearization are discussed. Further research tasks are presented. © 2021 IEEE.

A method for detecting signals with a random moment of occurrence based on the algorithm of cumulative sums with a reflecting screen under the influence of non-Gaussian noise is presented. An example of detecting a signal exposed to non-Gaussian quasi-deterministic additive noise is used for obtaining the dependences of the probability of false detection on the value of the signal-to-noise ratio for different values of the detection threshold. An increase in the detection threshold value, as well as the value of the signal-to-noise ratio, leads to a decrease in the probability of false detection. It is shown that the case of coordinated noise has the highest probability of correct detection. The algorithm for detecting a signal against the background of pulse noise and fluctuating non-Gaussian noise is analyzed and curves for probability of correct detection are obtained. It is found that the mismatch of the cumulative sum algorithm and the real density of probability distribution of noise leads to a decrease in the probability of correct detection. It is shown that the cumulative sum algorithm allows not only to solve the problem of detecting a signal in real time, but is also simple enough to be used when solving some practical problems. © 2021 IEEE.

We have developed a methodology that allows to develop recommendations for choosing a place to start lane changing with the intention to make a turn at a crossroad and choosing the duration of traffic light phases, and these durations may vary depending on the time of day. This methodology could be made on the basis of field measurements and a mathematical model of the traffic flow on a section of a multi-lane highway. There are actual to use Smart Light in ITS to control traffic on crossroads and to optimize the choice of traffic light phase durations. The developed model allows to calculate the distribution of traffic intensities on a section of a multi-lane highway. To verify and calibrate the model the distribution of traffic intensities has been calculated for a section of Leningradsky prospect, Moscow. The results of these measurements were compared with data obtained in measurements on the section. The model is based on the deterministic-stochastic control for traffic modeling in accordance of that the traffic flow is represented as the sum of the deterministic and stochastic components. The deterministic component corresponds to the velocity of a lattice movement, and the stochastic component corresponds to the velocity of the average particle movement. Using the deterministic-stochastic approach, we can obtain more exact evaluations of traffic characteristics. © 2021 IEEE.
