Abstract:

The relevance of the topic is related to the problem of protection and security of technical systems in the era of globalization and information warfare, as well as determining the strategic reserve of stability for production cycles. The study object was mathematical methods of modelling production processes and determining the point of the production system stability. The study purpose was to use the fuzzy set device to determine the point of stability of the production system. To implement this study, methods of statistical analysis, data grouping, sample ranking, and methods for studying time series components were used. During the study, the scientific materials of leading researchers in the field of fuzzy sets and mathematical methods to calculate various components were used. The study results are intended for specialists and researchers in the field of development and application of mathematical methods in the modelling of economic indicators of technological processes at enterprises.

Keywords:

fuzzy set theory, strategic security, technical systems, stability domain.

Abstract:

This article is devoted to the decision of the actual scientific and applied problem which consists in the development of a method of definition of levels of the basic and secondary electromagnetic radiations in the urban environments at the expense of perfection of models of their distribution. The necessity in the increased efficiency of use of devices of monitoring of an electromagnetic situation on the basis of the analysis of features of distribution of electromagnetic radiations in the urban environment and lacks of the existing mathematical device for their description is proved. The nature of the interference and the distance in real operating conditions and the corresponding graphical and mathematical dependences were obtained, which formed the basis of the method of improving the models of electromagnetic radiation propagation. Scientific methods of synthesis of the detailed structural scheme of processes of detection and localization of uncontrolled and unlicensed devices of information transmission on radio channels, including development of the software for definition of a zone of electromagnetic accessibility indoors are substantiated. An original approach, algorithm of functioning and methods of synthesis of search means in the conditions of radio interference and detection of sources of electromagnetic radiation are developed.

Keywords:

secondary electromagnetic radiation, electromagnetic reach, radio wave propagation, Hut model, COST 231 MWM, monitoring of the electromagnetic environment, attenuation factor.

Bokareva, A.A. Model of a document protection algorithm for a person based on biometric parameters // European Scientific e-Journal, September 17, 2020.

ESeJ: inn2020-09-002 ---------- DOI: 10.47451/inn2020-09-002 ---------- Certificate

Abstract:

This paper discusses the principle of an algorithm for protecting an identifying document using biometric data without using third-party servers for both storing and processing information. The entire operation of the system is focused on the transition from paper documents to the electronic (cloud) version without loss of uniqueness and security with the possibility of multi-copying and use outside the work of data transmission networks.

Keywords:

authentication, electronic document management, verification, personal identification, biometric parameters, personal data.

Bokareva, A.A. Personal authentication using verified electronic document // European Scientific e-Journal, September 15, 2020.

ESeJ: inn2020-09-001 ---------- DOI: 10.47451/inn2020-09-001 ---------- Certificate

Abstract:

The paper dwells on the research of the possibility of bringing personal identification documents to a digital format with guaranteed person authentication and verification of the document, based on the digitalization trends of modern society and the increasing capabilities of technical support to eliminate the likelihood of damage, falsification and other negative impacts on the existing document flow. The main problem in solving this problem is the choice of the most effective type of used biometric parameters of a person for reading, broadcasting and subsequent processing.

Keywords:

authentication, electronic document management, digitalization, personal identification, biometric parameters.
