Annotation: The article presents the results of implementing a quality management system at the enterprise. The study and analysis of the international standard ISO 9001:2015, as well as sanitary and epidemiological requirements for production control were carried out. The main requirements and rules for the implementation of input, operational and output control of products at enterprises at all stages of the product life cycle were identified and presented. In addition, it was determined what requirements must be met by enterprises to implement a quality management system. It is important to note that this work is necessary at the enterprise, as it has the following advantages: by improving product quality, product sales increase, the level of management of the enterprise and personnel increases, and cost savings are realized at the stages of development, production and operation. It follows that to implement a quality management system, it is necessary to set the following tasks: describe the company's processes, develop performance criteria and evaluate processes, develop the necessary documented information, implement documentation in all departments, familiarize them with the quality policy and goals, conduct timely internal audits for further SWOT analysis, and conduct an assessment by an external auditor in order to obtain a certificate of compliance. An important step in quality management is that the organization should not eliminate nonconforming results of processes, but should identify potential nonconformities, assess the risk with the preparation of a Protocol, plan and implement actions to reduce risks. Difficulties may arise: lack of understanding by the staff of the need to implement a quality management system, lack of a clear vision, mission, lack of complete information on processes, lack of quantitative and qualitative evaluation criteria, quality is defined as the quality of products, not as the quality of processes, resources, lack of monitoring of customer satisfaction. It is possible to overcome these difficulties only with the implementation of the quality management system according to ISO 9001, since the requirements prescribed in the international standard are a real tool for improving the efficiency of the enterprise, which will help bring the organization to a higher level of development.

Annotation: Singularly perturbed partial differential equations with small parameters with higher derivatives deserve special attention, which often arise in a variety of applied problems and are used in describing mathematical models of diffusion processes, absorption taking into account small diffusion, filtration of liquids in porous media, chemical kinetics, chromatography, heat and mass transfer, hydrodynamics and many other fields. It is necessary to consider the creation of an asymptotic classification of solutions of singularly perturbed equations using a well-known approach to solving the boundary value problem. In this case, the singular problem is understood as the problem of constructing the asymptotics of the solution of the Cauchy problem for a system of ordinary differential equations with a small parameter with a large derivative. The asymptotics of the solution in all cases is based on the last time interval or the construction of a boundary value problem for a system with a weak clot in an asymptotically large time interval. Purpose - to construct and substantiate the asymptotics of solving a singular initial problem for a system of two nonlinear ordinary differential equations with a small parameter; To date, a number of methods have been developed for constructing asymptotic expansions of solutions to various problems. This is the method of boundary functions developed in the works of A.B. Vasilyeva, M.I. Vishik, L.A. Lusternik, V.F. Butuzov; the regularization method of S. A. Lomov, methods of averaging, VKB, splicing of asymptotic decompositions of A.M. Ilyin and others. All the above methods allow us to obtain asymptotic expansions of solutions for wide classes of equations. At the same time, such singularly perturbed problems often arise, to which ready-made methods are not applicable or do not allow to obtain an effective result. Therefore, the development of methods for solving equations remains a very urgent problem. As a result of the study, an algorithm for constructing an asymptotic classification of the initial solution of the problem with a singular perturbation is given, and approaches to estimating the residual term are also shown.

Annotation: The article is devoted to the development of a technology for obtaining organic fertilizers from poultry waste based on biocatalytic processes. Currently, many poultry farms have become sources of environmental pollution, thereby causing serious environmental problems and economic and social damage. The problem of reliable protection of the natural environment from pollution by bird droppings is currently relevant. In the area of operation of large poultry farms, air pollution by microorganisms, dust, foul-smelling organic compounds, which are decomposition products of organic waste, as well as nitrogen, sulfur, and carbon oxides, is possible. Bird droppings contain acids, nitrogen, phosphorus and potassium, heavy metals. The content of nitrogen, phosphorus and potassium changes dramatically depending on the quantity and quality of the feed. Humic substances isolated from brown coal have a sufficiently high sorption activity and are used as cheap sorbents for solving a number of environmental problems in industry. These studies are aimed at minimizing the main disadvantage of the anaerobic digestion process, the low reaction rate, which leads to the need to create large-volume bioreactors. On the basis of the research carried out, a technology has been developed for obtaining organic fertilizers from poultry waste by the method of anaerobic fermentation of chicken manure with humidity at a temperature of 27 °C - 50 °C with the addition of sodium humate. The resulting fertilizer is intended for use in agricultural production, horticulture, floriculture, forestry, municipalities, in household plots in order to increase the yield and quality of crop production. For the developed technology, an application has been submitted for obtaining a Patent for the invention of the Republic of Kazakhstan «Method for producing organic fertilizers» (priority No. 2021-22818, dated July 13, 2021). The invention allows to significantly reduce the time of fermentation, to enrich the product with organic and mineral products contained in sodium humate, to convert the salts of heavy metals into an insoluble state, to improve the environmental friendliness of the method.

Annotation: Main problem: The article analyzes water quality assurance as the main goal of preserving human health. The study of chemical and microbiological parameters of wastewater and drinking water was carried out using generally accepted standards. The number of deaths associated with the use of contaminated drinking water, according to WHO, tripled in 2021 and reached almost 19 thousand against 6 thousand in 2020. In addition, the number of neoplasms, diseases of the genitourinary system, digestive organs and skin increased by 2 %, to 1.486 million. The reasons for the increase in the level of harmful chemicals and microbiological pollutants in the water are outdated sewage treatment plants, old pipes and disinfection with chlorine. Purpose: Study of the quality of wastewater and drinking water in Pavlodar, study of the quality of wastewater and drinking water in Pavlodar. Methods: Sampling of wastewater, chemical and bacteriological analysis of wastewater and drinking water, statistical method, correlation analysis of experimentally obtained results and calculated characteristics, etc. Results and their significance: In the field of public health risk, pollution of reservoirs that are sources of household drinking water supply and recreational water use, the continuing necessary high deterioration of water supply networks, their accident rate, as a result of low level of operation, failures in the operation of treatment facilities. Hygienic assessment of reservoirs according to complex indicators indicates the continuing high degree of water pollution in places of water use. The water quality indicators of the surface reservoirs of the region remain low in terms of sanitary and chemical (primarily organoleptic and general sanitary), as well as microbiological indicators. According to toxicological indicators, the level of water pollution in places of water use is estimated as moderate. The main pollutants of the Irtysh River in Pavlodar are industrial enterprises and housing and communal facilities that discharge untreated or insufficiently treated wastewater into reservoirs. A complex of causes of drinking water pollution has been identified: high deterioration of water supply networks, their accident rate, because of a low level of operation, failures in the operation of treatment facilities, unfair treatment of industrial wastewater by industrial enterprises of Pavlodar, etc. Priority preventive directions for improving the quality of water as a source of life are the implementation of long-term targeted planning of measures for the modernization of water supply and sewerage networks and facilities in Pavlodar. The state of water supply necessary and measures to improve it should be constantly monitored and considered at meetings of sanitary and anti-epidemic commissions.

Annotation: Combustion engines operate over a wide range of power and speed. To the greatest extent, this applies to automotive and tractor engines and diesel engines operating at fractional and idle loads for a significant part of the operating time. When designing engines, the choice of their main design and layout parameters is carried out in a comprehensive manner, taking into account the provision of the required power and efficiency in the modes of maximum torque and rated power. However, ensuring the economical operation of modern highly accelerated diesel engines at low loads and idling causes a whole range of problems related mainly to the organization of effective mixture formation and fuel burnout, as well as to ensuring stable fuel supply. Thus, the cycle dose of injected fuel in idle mode is 8–12 times less than the cycle dose in nominal mode, which determines increased requirements for fuel equipment and difficulties in ensuring high-quality mixture formation. At the same time, diesel engines operate in idle mode up to 50 % of the total operating time, consuming up to 15–20% of the fuel. For truck engines, the relative idle time is approximately 20–25 %. Thus, the development of measures to improve the efficiency of diesel engines at idle is relevant. The purpose is to perform a numerical analysis of the effect of switching off cycles in diesel engines for autotractor and diesel locomotive purposes on the working processes in the cylinder and the indicator parameters of the cycle in idle modes. When writing the article, traditional methods (comparison, description, and measurement), generallogical methods and research techniques (analysis, generalization, etc.) were used. A numerical analysis of the operating cycle of a diesel engine equipped with a cycle shutdown system was performed. The relationship between changes in fuel injection characteristics when cycles are turned off with indicator indicators of the engine operating cycle in idle load modes is disclosed. It has been established that the expediency of switching off cycles in a specific engine operation mode is determined primarily by the features of the injection, carburetion and fuel burnout processes.

Annotation: An analysis of the mechanical, chemical and pyrogenic impact of the Baikonur Cosmodrome on the environment showed the presence of man-made impacts of the first stages (FS) used on the ecosystems of the impact zones (IZ). This article presents the concept of a controlled landing of spent launch vehicles with liquid rocket engines (LRE) in the expected zones of damage to the ecosystems of the area while maintaining the energy-optimal launch scenario of the launch vehicle. Purpose of the article - development of effective technologies for reducing the anthropogenic impact during launches of promising rockets from the Baikonur Cosmodrome based on theoretical and experimental studies of innovative technologies: reducing the area of impact of parts from launch vehicles; fire and explosion safety, no danger of rocket launchers; controlled descent of used first stages; To solve the problem, it is proposed to create an additional IASM, which will be included in the environmental management system of the Baikonur Cosmodrome. Possible design solutions are proposed based on the evaporation of untreated liquid waste from the tanks of separated parts, their fire and explosion safety, and the use of the obtained vapor-gas mixtures for controlled unloading of separated parts while moving along the landing trajectory to the optimal area. The authors of the article have developed evaluation criteria that characterize the main environmental indicators of the studied areas: fire hazard, soil cover and impact on vegetation are studied for inclusion in the IASM. There are objective requirements and basic rules for the creation of HIASM, which is an integral part of the environmental management system of the cosmodrome.

Annotation: The paper considers two data-driven methods for anaphora resolution of Kazakh texts. These methods are based on machine learning with annotated corpora and using no additional information except linguistic features. The first method uses Support Vector Machine as learning and classifying algorithms, the second method uses Decision Tree inducer. We evaluate the performance of the methods with several feature sets and corpora. Feature sets included morphological, syntactic, and semantic features. In this paper We also evaluate how semantic features, namely semantic roles, impact the performance of anaphora resolution in Kazakh language. Experiments showed that precision of SVM is higher on experimental data for almost all cases. It was shown that semantic features enhance the performance of the methods for anaphora resolution of Kazakh texts. We have also calculated the optimal distance between the anaphor and the hypothetic antecedent and used it in our methods.

Annotation: Main problem: Today electronic information is one of the important resources in the management system. Electronic information resources are not only means, but also control flows. For example, any instruction or instruction in the management system is actually a guide to action. At the same time, for example, data on the movement of an object (employees, goods, money, etc.) are information resources, the storage and accounting of which is the basis of the organizational process. Large flows of information require their structuring, and operations on them become time-consuming. One of the ways to solve this problem is the development and implementation of an information system. Purpose: To analyze and design an information system using specialized tools designed to optimize the implementation of the above stages of software system development, using the example of a real business process. Methods: The article discusses the methodologies of CASE tools designed to automate software development processes, namely, the first two stages of the life cycle: analysis and design of a software product. The analysis and design of the business process functionality is carried out using the IDEF0 functional modeling methodology. The design of the database structure of the information system was carried out using the methodology of semantic (information) modeling IDEF1X. Description of the scenario of the designed software for a real business process is carried out using the dynamic modeling methodology IDEF3. Results and their significance: The article substantiates the relevance of the use of modern CASE-technologies in the process of analyzing and designing a future information system, as well as for the purpose of possible optimization on the example of a real business process "Inventory accounting". As a result, a comprehensive business process model was built using tools based on CASE-methodologies. The resulting model, as well as the description of its construction, is a clear example of the use of CASE technologies for software developers, as well as system analysts and IT specialists.

Annotation: Main problem: The use of waste heat is most often solved by installing heat exchangers, but this is not effective when the temperature of this heat does not exceed 10-15 0 C, in which case this heat can be used using a heat pump. Where can I get this heat? Almost any enterprise needs cooling of any equipment elements or substances – working fluids; the heat received from them can be sent to a heat pump and used here at the enterprise. Purpose: Consideration of the possibility of using the heat of cooling water from the pump CNS 60-165 and the proposal of a new scheme with the installation of a heat pump that uses this heat. Methods: This is achieved due to the fact that it is proposed not to discard the heat, but after its use in the heat pump evaporator, transfer it to the heated medium - water, which is then sent to the shower cabins of the enterprise. Since the showers are located in the same room, the cost of transporting heat and losses will be minimal. Methods: In the course of the research, the possibility of using the waste heat of an industrial enterprise for using it here at the enterprise for the purposes of hot water supply was considered. For these purposes, it is proposed to install a heat pump, thanks to which the thermal potential increases, which makes it possible to fully use the received heat. Results and their significance: As the experience of foreign countries has shown, heat pumps can be widely used in many industrial enterprises, and in conditions of increased competitiveness, in order to reduce energy costs and the cost of manufactured products, install heat pumps to utilize excess heat, for example, process water, which is available in many production allows you to have a significant economic effect.

Annotation: Main problem: recently, much attention has been paid to energy saving in production, especially when it comes to industrial units that burn fuel. There are several ways to maximize the use of the heat released during the combustion process, for example, to reduce the temperature of the flue gases at the outlet of the unit, by maximizing its use, both in the technological process itself and by installing additional heat-receiving units, for example, air heaters or other heaters. Another way to save money is to reduce heat losses through the lining of these high-temperature units. Metallurgical units that consume a large amount of energy and fuel require an analysis of their consumption, and ways to save their consumption based on the results of the analysis. Purpose: this article considers the possibility of replacing the existing inner insulation layer of the second and third sections of a high-temperature unit - a metallurgical furnace, with a new one with better technical and economic indicators. Methods: the possibility of replacing the existing inner insulation layer of the second and third sections of the high-temperature unit with a new one, with the best technical and economic indicators, was considered. The calculation of heat losses by thermal conductivity through the side surfaces and the roof with new insulation was performed, and the economic efficiency of the proposed solution was proved. Results and their significance: replacing the existing inner layer of insulation - refractory concrete PHLOCAST M30 (thermal conductivity coefficient from 1,4 to 1,45) with the proposed CERALIT GUN HK 70070 (thermal conductivity coefficient from 1,03 to 1,12) will reduce heat loss to the environment, and thus to reduce fuel consumption for the furnace.
