Ensuring the required level of quality of products produced by textile enterprises involves not only the final (output) control of its quality indicators, but also ensuring operational control over the relevant characteristics of raw materials and semi-finished products in technological processes throughout the entire production chain of textile material. Within the framework of the functioning of the quality management system of a textile enterprise, when conducting operational monitoring of technological processes, appropriate automated technical controls are required, built with the use of modern information technologies. In this paper, in order to assess the quality of the carding process in the production of combed or carded yarn, a method is proposed for the digital study of the structural unevenness in the surface density of this type of non-woven material, based on the principle of determining the sectorial and radial characteristics for this quality indicator.

The Relationship

The interaction of quality management and knowledge man­agement are analyzed quite widely in scientific literature and discussed with reference to various models integrating these two management theories. However, there are not enough precise tools that could provide a possibility of improving the quality of products and services through knowledge management. To this end, the article examines the already existing models for the interaction between quality management and knowledge management. The results of a survey on Lithuanian industry show what organizational knowledge is the most important while implementing quality management principles aimed at improving quality. The correlation analysis method showed the relationship between quality management principles (process approach, continual improvement, management, facts) and the factors defining the product and process quality (the extent of determining process execution time, process resources, costs of process stages, indicators for products and/or services, the dura­tion of the process, the extent of measuring indicators, the extent of collecting information on indicators, the extent of collecting information about the costs of the process). Santrauka Kokybės vadybos ir žinių vadybos sąveika mokslinėje literatūroje analizuojama gana plačiai, aptariami įvairūs sąveikos modeliai integruojant šias dvi vadybos teorijas. Tačiau nepakankamai nagrinėjamos konkrečios priemonės, kuriomis būtų galima pagerinti produktų ir paslaugų kokybę pasitelkiant žinių vadybą. Tuo tikslu straipsnyje analizuojami jau egzis­tuojantys kokybės vadybos ir žinių vadybos sąveikos modeliai bei pateikiami Lietuvos pramonės įmonių tyrimo rezultatai, parodantys, kokios organizacinės žinios svarbiausios įgyvendinant kokybės vadybos principus, skirtus kokybei gerinti. Taikant koreliacinės analizės metodą nustatyta, kad egzistuoja ryšys tarp kokybės vadybos principų (procesinio požiūrio, nuolatinio gerinimo, valdymo remiantis faktais) įgyvendinimo lygio ir veiksnių, apibūdinančių produktų ir procesų kokybę (procesų įvykdymo laiko nustatymas, procesų išteklių nustatymas, procesų etapų išlaidų nustatymas, produktų ir (ar) paslaugų rodiklių nustatymas, rodiklių matavimas, rodiklių informacijos rinkimas, informacijos apie proceso trukmę nustatymas ir informacijos apie proceso išlaidas rinkimas).

Linseed (Linum usitatissimum L.) and fi bre hemp (Cannabis sativa L.) can be used as raw materials in various applications. In this study, microbiological quality and meteorological measurements were made during the growing seasons and harvesting periods of 2001 and 2002. The microbiological analyses were carried out with Hygicult® TPC and Y&F dipslides, and with a surface spreading method using Plate Count and Potato Dextrose agars. During the growing season of 2001 the conditions were mostly humid, whereas the growing season of 2002 was rather dry and warmer than that of 2001. The lack of water during the growing season of 2002 affected the growth of the plants. In the case of both hemp and fl ax, the mould and bacterial contents (cfu gdw-1) increased markedly at the end of the growing season of 2001. During the growing season of 2002 the increase in mould and bacterial contents was noticeable but more constant throughout the whole growing season. At the end of the growing seasons, the mould and bacteria contents were higher in 2001 than in 2002. The genera of moulds identifi ed included Cladosporium, Fusarium, Penicillium, Mucor and Alternaria. The microbiological safety should be controlled during the whole production chain, beginning with the cultivation and harvesting periods.;

The high-speed growth in the global population has resulted in a deficit of foods, which has stimulated the development of technologies for planting agricultural products and fattening domestic animals. However, these processes are supplemented in many cases by worsening of the quality of foods and their pollution by foreign substances. To guarantee the proper quality and safety of foodstuffs for health, the International Organization for Standardization developed the standards ISO 9001:2015 and ISO 22000:2018. At the same time, businesses fabricating foods, especially meat-based ones, have to observe the norms of the international standard ISO 14001:2015. Finally, because treatments of raw materials and ingredients used in food products contain in many cases substances harmful for health, enterprises must introduce the norms of standard ISO 45001:2018. To simplify management processes, enterprises introduce so-called ‘integrated management systems’. This study proposes one variant of such a system recommended for use in food-producing organizations including those that treat raw meat and produce products based on its use.

Quality Of Milk

The most pressing problems of the food industry today are the quality of food. The main factors influencing this indicator are the quality of raw materials, the technical and technological level of enterprises, the quality management system and food safety. Milk quality cannot be improved in the processing process, at best it can be stabilized, so the milk quality management system should focus on the technological processes of its production and primary treatment using a preventive approach. The sanitary and hygienic quality of milk production is a complex problem that is determined by a number of factors that combine the notion of "technology and culture of production". General bacterial contamination of milk raw materials should be considered as a collection of sources of ingress of microorganisms into the technological environment, in particular the microflora of the surface of the udder and lobes; microflora of udder channels; microorganisms of milking equipment, milk lines, milk packaging; microflora of personnel and environment. The traditional scheme of primary milk treatment provides a consistent picture of the quality and safety of raw milk obtained from its production. Measures to improve the quality and safety of raw milk through additional use of the decontamination process are proposed. The use of ultrasonic cavitation technologies for milk disinfection allows to increase the quality of milk and to get more money for the farm, to provide quality raw materials for dairy enterprises.

The introduction of a quality management system is important because it leads to improved productivity, optimization of business processes of the organization, and also leads to a reduction in production costs. The article considers the theoretical aspects of the quality management system at the enterprise, outlines the methods and classification of existing quality management systems. The essence of legal regulation of the quality management system is investigated and its current state is characterized. It is noted how some experts classify quality management methods. Recommendations for improving the quality management system at a domestic enterprise are offered. Emphasis is placed on the fundamental standards of ISO 9000 and how they are integrated into the state standards of Ukraine. When developing quality management systems, it should be borne in mind that the quality management system covers all processes that occur in the enterprise and on which the quality of products or services depends. According to the capabilities of the production process, the stages of the product life cycle are considered, which should be used at the appropriate stages of development and certification of the quality management system. The task of improving the quality and expanding the range of products is relevant in modern production conditions. This task is multifaceted and includes a number of scientific and technical, environmental, economic and social problems. An interdisciplinary approach is needed for an effective solution. One of the ways is product quality management based on assortment analysis and its innovative development. The experience of developed countries shows that the health of the nation, primarily through food, their safety, is more reliable when it is achieved by improving the quality of products based on standardization worldwide and internationally. At the international level, quality requirements are regulated by ISO standards, strictly focused on the consumer. The first such standards were the standards of the 9000 series, which came out in the late 80's pp. XX century More than half of the world's countries have implemented national standards identical to ISO standards, as well as certified enterprises in accordance with ISO standards.

Risk assessment is an integral part of an enterprise's quality management system. The risk of low quality products is the most significant risk, as it is directly related to the concept of enterprise competitiveness. The paper analyzes the scientific papers related to the assessment of the quality of products, processes and services, their disadvantages, possible limits of application. It is proposed to use mathematical dependences to obtain estimates of product quality indicators on a dimensionless scale. Knowing the density function of random variables of product quality indicators and knowing the mathematical dependence of their estimates on a dimensionless scale, it is proposed to obtain the density function of estimates. Knowing the function of the density of estimates of quality indicators, it is proposed to find the probabilities of risks of the assessment of quality indicators in any given interval on a dimensionless scale. A method for assessing the risks of low quality products has been developed

Currently, it is necessary to build a product quality management system that ensures the smooth operation of the organization, the competitiveness of products, the development and maintenance of the organization's quality goals. The article discusses the theoretical foundations of quality management of manufactured products at the enterprise. The necessity of quality management of the enterprise's products as the basis of the competitiveness of the enterprise is substantiated. The concept of quality management is considered. The stages of development of the quality management system are given. The threats of defective goods and their impact on the economic condition of the enterprise are considered. At the research stage, the Ishikawa causal diagram was used, developed using the 6M mnemonic technique. The quality control system of metal structures is analyzed. Losses from defects in the manufacture of metal structures were revealed. A Pareto diagram of the defected goods distribution is constructed, the data of which indicate that more than 55 % of the defects is caused by locksmiths, 17 % — undercuts, 13 % — displacement of holes and other reasons. The main reason was the insufficient level of qualification of locksmiths. In order to improve the quality of products, measures have been proposed concerning the retraining of workers, updating equipment. It is recommended at operational meetings to develop preventive and corrective measures to reduce defects, reduce the workload of engineers of the technical control department. The suggested measures will reduce the number of defective products, increase the competitiveness of the company's products.

Разработана технология получения желейного мармелада повышенной биологической ценности с использованием пищевых волокон. В качестве объекта исследований выбран желейный мармелад как имеющий низкую пищевую ценность, большое до 70 количество углеводов. Для обогащения изделия использовали растворимые пищевые волокна олигосахариды в виде препарата инулина в количестве 6 по массе выхода, что соответствует характеристике изделия с высоким содержанием пищевых волокон согласно ТР ТС 022/2011. В качестве студнеобразователя использован желатин в количестве 7 к желейной массе. Определено оптимальное соотношение сахара и патоки 2 : 1 соответственно. Установлено, что при добавлении инулина в количестве 6 повышается вязкость желейной массы на 0,7 Па с, что не затрудняет процесс формования количество редуцирующих веществ увеличивается на 0,4, что не ухудшает качества изделий. Доказана возможность использования препарата инулина для обогащения желейного мармелада пищевыми волокнами и получения изделий функциональной направленности. The technology of obtaining jelly marmalade of increased biological value using dietary fibers has been developed. As an object of research, jelly marmalade was chosen as having a low nutritional value and a large amount of carbohydrates up to 70. For the enrichment of the product, soluble dietary fibers oligosaccharides in the form of the preparation of inulin were used, in the amount of 6 by weight of the yield, which corresponds to the characteristics of the product with a high content of dietary fibers according to TR CU 022/2011. Gelatin in the amount of 7 of the jelly mass was used as a gelling agent. The optimal ratio of sugar and molasses 2 : 1, respectively, determined. It was found that the addition of insulin in an amount of 6 increases the viscosity of the jelly mass by 0,7 Pa s, which does not complicate the molding process. Also, the number of reducing substances increases by 0,4, which does not worsen the quality of products. The possibility of using the preparation of inulin for the enrichment of jelly marmalade by dietary fibers and the production of functional products has been substantiated.

In view of increase of demand in treated wire for springs of critical application and measures implementation for import substitution, perfection of technological processes of its production becomes actual. Basic technical requirements to spring wire as per domestic and foreign standards presented, the factors effecting the quality of finished products considered. Description of technological processes of hardened-tempered spring wire of critical application presented. It was shown that domestic technological scheme of treated wire production is analogous to foreign one, however to reach the quality of products, correspondent to norms нормам EN 10270-2:2012, a perfection of it is needed. Proposals to improve the technology of manufacturing domestic competitive products elaborated. Among them a necessity to use steels of Si‒Cr or Si‒Cr‒V system, additionally alloyed by manganese, cobalt, tungsten a(or) other elements highlighted. It was proposed to implement an operation of scalping instead of turning and a system of nondestructive control, to use resource-saving routes of wire drawing with high uniformity of properties, to replace hardening and tempering by thermomechanical treatment (for some kinds of wire), to use modern highly-productive equipment.
