So, Ukraine, in this case, is not an exception. National science, medicine, industry, and other fields of activity increasingly feel the need for reliable and traceable results of mass measurements in the range of more than 1 kg. Considering this, a national standard of the unit of mass in the range from 2 kg to 20 kg was established in SE «Ukrmetrteststandart». This article provides information on the general structure of the national standard, its metrological characteristics, and the methods of its application. It is also described the dissemination procedure of the unit of mass from the 1kg reference weight to the weights in the range from 2 kg to 20 kg, as well as the processing of the obtained measurement results by means of the least squares method. In addition, the article presents the results of the national standard’s research, the results of the calculation of the masses of the standard weights, and their uncertainty assessment. The obtained results confirm compliance of the metrological characteristics of the national standard to the declared ones. It has been demonstrated that the national standard provides calibration of weights of accuracy class E1 in the range from 2 kg to 20 kg.","PeriodicalId":139019,"journal":{"name":"Measurements infrastructure","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121760879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cherepkov","doi":"10.33955/v5(2023)-024","DOIUrl":"https://doi.org/10.33955/v5(2023)-024","url":null,"abstract":"Development of DIMSCC models with cyber-controllability of their apparatus and software for computing function (operations) in real time becomes the primary task since the problem relevance of the cyber security of digital information and measuring systems of control complexes (DIMSCC) for critical infrastructure objects is increasing. Based on an analysis of known digital systems functional control methods new term «functional cyber-controllability of the digital informational and measuring system» was defined in the article. New approach to operational functional control of hardware redundancy is proposed. This is the synthesis of DIMSCC computing operations. Hardware redundancy is a synthesized control node chosen for functional control of various DIMSCC basic arithmetic and logical functions (operations) which should be reduced to simple procedure of corresponding switching functionally complete combinational structures from a finite set (standard set). Concerning this, the synthesis task is as follows. Only inputs and outputs of specified object are available for functional control of arithmetic and logical operations on binary operands under external hacker influence. Combination type functional control node structure (operational compositional adaptation) should be developed depending on the type of controlled computing operation being performed. The result of the synthesis task solving is a system of formulae determination (signature control equations) of the signature functional control of all DIMSCC basic arithmetic and logical functions (operations) on a single basis of a single equivalent representation of their known formulaic expression by corresponding (adequate) descriptions in infix notation (infix models). Apparatus of Boolean-polynomial algebra is used aiming to realize infix notation. The practical advantage of the proposed approach to the synthesis of hardware redundancy of operational functional signature control of computing operations is the transition possibility from signature control equations formulae to their realization implementation in the form of a signature control node directly without additional interpreting and minimizing procedures use by simple logical composition (switching) functionally complete combinational structures from a finite set (standard set).","PeriodicalId":139019,"journal":{"name":"Measurements infrastructure","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124336903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Model is based on complex causal-consequential chains character of two processual authors models: «enterprise business value creation chain» and «process management pyramid». The enterprise business value creation chain is determined as a logical sequence of digitalized technological business processes (TBP) of business value creation chain: customer/consumer engagement, production organization, goods production/services provision, goods/services sales. Herewith, «enterprise created business value» concept means the complex of two target production results: produced goods/services in terms of value for customer and sales revenue received on the seller bank account is value for the enterprise. Office automation systems (OAS) in all levels of the enterprise process management pyramid are used as an instrument for information collecting and processing and primary accounting data submitting from each technological business process in the value creation chain and analytical management data from managers personal business processes. This system is a corporate enterprise portal having an Internet connection. Herewith, «enterprise process management pyramid» concept is considered a digital organizational management structural model for the process-oriented enterprise. The structure model is a hierarchical system of managed by known PDCA (plan — do — check — act) management cycle internal and interrelated functions of each manager and lower (adjacent) level directly subordinate managers whose aim is managerial decisions production for directly subordinate executors. Concerning digitalized process-oriented enterprise management model, a vision of possible internal accidents and enterprise automated management system database hackers distortions model is created.
