Production quality control in new conditions

An attempt has been made to generalize and analyze the situation with product conformity assessment that has developed in the country today as a result of the actual cancellation of a significant part of control and supervisory measures to facilitate business in extraordinary external conditions. Risks and guidelines for the development of quality infrastructure are noted.

Keywords: quality, safety, control, supervision, market, products, conformity assessment, simplified procedure, competence, testing, accredited laboratory, import substitution

Monitoring the sulfur content in automotive gasoline

Ensuring the quality of automobile fuel is an urgent problem in Russia. The purpose of the article is to analyze the situation with the compliance of the quality of gasoline with the established physico-chemical characteristics. The emphasis is placed on the content of sulfur compounds in petroleum products, which have a significant impact on the operational properties of the car and the degree of engine wear.

Keywords: quality, petroleum products, automobile gasoline, mass fraction of sulfur, technical regulations, gas station, ecological classes of gasoline

Reliability and safety of hydrogen-fueled road transport infrastructure

The article is devoted to the analysis of approaches to ensuring the reliability and safety of hydrogen motor transport from the standpoint of the technical reliability theory of, technosphere safety and risk management. Using the example of an operating hydrogen filling station, the problem of modeling the parameters of an explosion of a hydrogen-air mixture is considered. An analysis of the consequences of the accident is carried out, an estimate of the size of the sanitary zone for this object is presented. Recommendations are given on modeling emergency events at the objects of automotive transport infrastructure, improving their reliability and safety.

Keywords: hydrogen transport, safety of transport infrastructure, hydrogen filling station, maximum credible accident, explosion of gas-vapor mixture

Specifics of testing of gas cylinder equipment of cars

The article is devoted to the specifics, content and problems of testing gas cylinder equipment. The author raises the question of the need to harmonize Russian requirements and standards of a technical nature with European ones, as well as the development of new documents in this area. In addition, the features and complexities of the work of testing laboratories are considered in detail on the example of real practice, negative cases are shown and possible ways out of situations concerning test procedures are proposed.

Effective approaches to GMO screening in food, feed and raw materials

The article gives an idea of the system of regulation regarding the labeling and detection of genetically modified organisms in the Republic of Belarus and the member countries of the EAEU Customs Union, the interaction of republican, union and international requirements in this area. The methodology of screening the increasing diversity of GMO lines, the role of databases for the development of its effective schemes, approaches to the identification of new generations of GMOs, as well as the problems of their detection are highlighted. A detailed description of a universal web platform for the search and exchange of information about GMOs is presented.

Keywords: conformity assessment, product labeling, genetically modified organisms (GMOs), genetically modified ingredients (GMIs), GM line, polymerase chain reaction (PCR), screening, database.

Development and application of a comprehensive quality indicator of the motor gasoline compounding process

Compounding of commercial fuels is an important final stage of the entire technological chain of oil refining production, which determines its economic efficiency. The development and application of a complex indicator of the quality of the compounding process of gasoline is considered, on the basis of which a mathematical apparatus for automated search for the optimal mixing recipe is formed. The experience of its application shows the possibility of increasing the profit of the enterprise and improving the quality management system of products in the process of compounding gasoline.

Keywords: gasoline compounding, quality management system, quality indicator, complex quality indicator

Quality control of cyber-physical systems by probability distribution densities of random functions as criteria characteristics. Part 2

A mathematical model is presented that provides an increase in the reliability of quality control at the stages of design, technological preparation and serial production of CPS at an arbitrary point in the processes. The result was achieved on the basis of the transformation of the original stochastic differential equations into differential equations with respect to the probability densities of the current inconsistencies, performed iteratively. The mathematical model provides control of the object at all stages of design and production “top-down” - forward pass, adjustment of model parameters “bottom-up” - reverse pass. This example illustrates the possibilities of the technique at individual stages.

Keywords: tools, cyber-physical systems, mathematical models, probability distribution densities; digital design and manufacturing.
