There is strong competition between pharmacy providers. The abundance of advertising allows the public to be relatively informed in the variety of medicines offered by suppliers. All of the above, including high rent for inventory storage space, emphasizes the problem of the need for rational assortment formation. Only a properly created assortment of goods will allow the pharmacy to compete in the eyes of consumers, not to lose regular customers and to acquire new ones. With effective management of the product assortment can increase the income of the pharmacy due to the lack of unsatisfied demand. It is also possible to reduce the number of sales lost due to lack of goods, to accelerate the turnover of goods, to reduce the cost of storing medicines. Currently, there is a variety of combination medicines offered by suppliers to combat several symptoms of acute respiratory viral infections. The article presents the results of ABC-analysis, XYZ-analysis and their combination on the example of the assortment of dosage forms of antigrippin of the pharmacy of the state network of the city of Kazan. The distribution of antigrippin assortment into groups is shown and recommendations on the strategy of the pharmacy manager in relation to each of the groups are offered. The fact that these are seasonally consumed commodities with medium forecasting capabilities makes it difficult to plan the procurement of combination medicines to control several symptoms of acute respiratory viral infections. After combining the results of ABC XYZ analysis, it was found that antigrippin pharmacy-made antigrippin and antigrippin effervescent tablets are commodity items with a low share of turnover and number of sales units. They showed a medium degree of forecast reliability due to unstable demand. Antigrippin express powder, antigrippin - ANVI capsules and Vicks Antigripp Max powder made up the majority of the assortment, a small share of the turnover of antigrippin dosage forms and the number of sales units. These products showed low forecast reliability due to non-constant demand and generated little profit. This could be due to the fact that the consumer did not have sufficient information about these products.

Utilization of the intersection of ABC and XYZ analysis in stock planning in the warehouse by Covid period

The aim of this article is to find the most appropriate inventory storage strategies in a new warehouse according to the Covid period. Based on the company's analysis and preferences, we have concluded that the most suitable inventory storage strategy will be ABC, XYZ and penetration analysis according to which the inventory will be produced to the company's warehouse. The result of the paper is the intersection of these analyses. Based on the penetration analysis, we found that AAXX group has 27% of the product items. The CXX group of manufactured items has a high turnover, but accounts for only 1% of the total items. The AA category has a low turnover but accounts for only 0.63% of the product items. As a result of the penetration analysis, we concluded that the categories AAXX, AAX, AXX, AX and BXX are suitable to be produced in large quantity in stock. For categories AAY, AY, BX and BY, it is recommended to plan the production of items for stock with caution and not to produce them in such large quantities. The regularity of the analysis of these methods is very important. The intersection of ABC and XYZ analyses indicates the regularity of applying these methods due to the existence of excess or non-replenishable stocks.

Pharmacoeconomic aspects of drug provision for diabetic patients in the Novosibirsk Region

Aim – to assess pharmacological and economic aspects of drug provision for patients with diabetes mellitus in the Novosibirsk region at federal and regional levels for the period of 2019–2021. Material and methods. An array of data on drug provision for diabetic patients in the Novosibirsk region for the period of 2019–2021 was collected and subjected to analysis. The research process used a systematic approach with the following methods: logical analysis, content analysis, ABC analysis, XYZ analysis. Results. For the period of 2019–2021, the burden on the regional drug provision system for diabetic patients had been steadily increasing. At the same time, the share of costs for drug provision for diabetic patients at the federal level continued to grow, despite the reducing number of covered prescriptions. Potentially, it could be explained by the constant increase in the average cost of a prescription. The ABC/XYZ inventory analysis of the consumed drugs and medical devices showed an increasing need for additional (non-hypoglycemic) medicines for the treatment of complications and concomitant diseases in diabetic patients. A greater increase in prescriptions of additional medicines and their funding was observed at the regional level in the period of 2019–2021.

The development of a fly ash-based geopolymer for extrusion-based 3D printing, along with a printability prediction method

This paper presents insights into the design and development of a geopolymer consisting of fly ash and ground granulated blast furnace slag (GGBFS) usable for extrusion-based 3D printing. It also reports on factors influencing the printability of the geopolymer, such as the amount of GGBFS, the solids content, mixing time, and activator ratio. Besides measuring the setting behaviour, the yield stress, and the ultrasonic velocity, we also conducted a modified flow spread test to investigate the geopolymer’s early physical material properties. We also used analytical methods (SEM, XRD, and TG) to explain its physical behaviour. We introduced an adjusted test for the flow spread (VFS test), which gives information about the thixotropic behaviour depending on the shear stress and the opentime for printing. By comparing the derivatives of the yield stress curve with printing tests on an XYZ gantry printer and analysis of the yield stress measurement’s transition point, we also present a unique method that allows researchers to assess the printability of the geopolymer solely on one small-scale laboratory tests without requiring printing tests on a physical 3D printer.

Implementation of ABC - XYZ Analysis on Business Inventory Management using Machine Learning Model Technology By IJISRT

This paper presents a novel approach to optimize business inventory management through the integration of ABC-XYZ analysis with advanced machine learning models. Inventory management plays a critical role in the operational efficiency and profitability of businesses across various industries. Traditional methods such as ABC analysis and XYZ analysis have been widely used to classify inventory items based on their importance and demand variability. However, the effectiveness of these methods can be further enhanced by leveraging machine learning techniques to analyze historical data and make accurate predictions. In this study, we propose a framework that combines ABC-XYZ analysis with machine learning algorithms to classify inventory items and optimize inventory control policies. We demonstrate the effectiveness of our approach through a case study conducted on a real-world business dataset, highlighting significant improvements in inventory turnover, cost reduction, and customer satisfaction.

GROUPING OF EU COUNTRIES ACCORDING TO THE LEVEL OF ECONOMIC DEVELOPMENT AND STABILITY OF ECONOMIC PROCESSES BASED ON ABC-XYZ-ANALYSIS

The study of economic development and the stability of economic processes of countries is a critically important task, as it helps to understand and analyze the processes taking place in the economic systems of countries. Countries differ significantly in terms of economic development, and their grouping according to certain parameters helps to better understand the general picture of the economic state of the country. The article proposes to group EU countries according to the level of economic development and the level of the economic processes’ stability based on GDP and GDP per capita indicators using ABC and XYZ analysis. The study was conducted on the basis of the countries of the European Union (EU) for the period 2015-2022 since the EU is a large regional association of countries with common economic, political and social goals. The statistical data of the World Bank served as the information base. The existence of discrepancies for countries between the level of GDP and the level of GDP per capita was revealed. Ukraine was also ranked according to the level of economic development and the level of the economic processes’ stability based on GDP and GDP per capita indicators since this country is a candidate for EU membership in 2022. The results of the study will help to understand the mosaic of the economic situation in different EU countries and highlight key conclusions for further research or decision-making. This information can be useful for understanding the main trends in the economy of the European region, identifying possible areas for cooperation and investment, as well as for developing strategies to improve development and stability in each of the EU countries.

АНАЛІЗ АСОРТИМЕНТНОЇ ПОЛІТИКИ ТОРГОВОГО ПІДПРИЄМСТВА ТА НАПРЯМИ ЇЇ ВДОСКОНАЛЕННЯ

The purpose of the article is to analyze the assortment policy of a trading company and search for directions for its improvement. The conducted analysis proved that the problems of forming an assortment policy are mostly connected with too huge assortment of goods on the market, with changes in customer needs and the growth of non-price competition. The specificity of the problem of the Ukrainian market is further complicated by the active hostilities in the country and related economic instability, inflation, low level of solvent demand, low level of population income growth, problems with the delivery of goods, etc. The essence of the concept of “assortment policy” as a field of activity of the marketing management of the enterprise is defined, which is a set of principles, the observance of which leads to the formation of an optimal assortment of goods from the point of view of increasing the competitiveness of the enterprise, taking into account its own capabilities, the capabilities of suppliers and partners, market needs, seasonality of demand, etc. Based on the ABC analysis for the “EVA” line of stores, it is emphasized that the most significant products are decorative cosmetics, perfumes for women, their share in the total turnover is on average almost 20%, they and other important products for the company belong to the category “A “, that is, they are the most important and significant, their share in the sum is 60%. The “B” group, which assumes medium significance, includes aromas, scented candles, atomizers, etc. Their share in total is 30%, it is the basis of the chain’s range of stores. The smallest share is occupied by goods of the “C” group, which are the least significant in terms of the turnover of the “EVA” line of stores: shaving products for men, cosmetic brushes, jewelry, etc. Their share in total is only 10%. An XYZ analysis was carried out for the “EVA” line of stores, the results of which show that the products marked X are products for which the demand is stable throughout the year (hygiene and care, home care products, home fragrances, etc.); products Y remain relatively stable throughout the year and products Z are volatile products, the coefficient of variation of sales volume by quarter exceeds 20% (sun protection, lip care, etc.). An integrated matrix of ABC-XYZ-analysis was built, which proves that the “EVA” store line carries out a balanced assortment policy, but does not saturate the assortment sufficiently with those items for which a higher level of profitability can be obtained, which leads to a rather low profit in recent years. For the company, the absence of product groups that can be attributed to the CZ classification, which are products of spontaneous demand, in the product range is noticeable, and therefore, increasing the product range in favor of such products can provide an opportunity to obtain a higher level of profit. It is recommended that the company continue to work on the development of new own brands and the creation of new product positions among the old ones, expanding the assortment in the “average” and “average minus” price segments.

АВС-XYZ-ANALYSIS IN THE MANAGEMENT OF RECEIVABLES OF THE ENTERPRISE

The article examines topical issues of application of ABC and XYZ analysis in the management of accounts receivable of an enterprise. The purpose of the article is to select criteria for conducting ABC-XYZ analysis of accounts receivable to assess the credit rating of buyers and apply appropriate debt collection methods for each group of debtors. The study found that accounts receivable is a form of commodity lending, and its volume significantly affects the financial condition of an enterprise. The article considers topical issues of accounts receivable management at enterprises in modern conditions as a prerequisite for strengthening payment discipline. The essence of ABC-analysis as one of the mathematical and statistical methods of analysis used for management purposes is investigated. The advantages and weaknesses of ABC analysis are identified. It is proved that for the formation of the credit policy of enterprise, to determine the credit rating of debtors, it is advisable to choose such parameters of ABC analysis as sales volume, terms of delay in payments and the amount of overdue receivables in absolute and relative terms. The credit rating of customers using the ABC analysis is built. A matrix of the combined results of ABC and XYZ analysis is presented, where nine groups of debtors are allocated, each of which requires the development of its own management technology. The main groups of methods of debt collection from debtors have been identified, the use of which will help to reduce the risk of non-payment of debts by buyers and will help to establish an effective credit policy at the enterprise. Further research should be aimed at expanding the methodological tools for managing the accounts receivable of an enterprise.

Influence of unregulated storage conditions on physico-chemical, organoleptic and NIR spectral characteristics of yellow cheese

In the present work, software and hardware tools are proposed for determining the change in the main characteristics of Bulgarian yellow cheese during storage in conditions not regulated by the manufacturers. NIR images in the 800-1100 nm range of yellow cheese samples from 3 manufacturers were obtained using a GT-903 video camera with the IR-filter removed from the camera lens. Several physicochemical characteristics of the product were determined - active acidity, electrical conductivity and completely dissolved solids. Data from organoleptic evaluation of the product are presented. Using ABC- XYZ analysis, informative wavelengths are selected from the spectral features. Spectral indices calculated as ratios of the reflectance coefficients of selected wavelengths were defined and used to predict the storage characteristics of yellow cheese. It has been found that the shelf life of yellow cheese can be predicted with an accuracy of up to 95%, and the active acidity with an accuracy of up to 88%, depending on the manufacturer. The obtained results can be used for analyzes of yellow cheese during its storage and applied in automatic measurement and control systems, as well as in advisory systems for evaluating the quality of yellow cheese in the different stages of its production, transport and storage.

Logistic approach to the segmentation of the company's customers as a basis for the formation of logistics services

The article defines the essence of the logistics customer service concept, as a component of the service process, which makes it possible to ensure the necessary level of the customers’ needs satisfaction, while providing the minimum necessary level of costs and maximizing profit for the company. It was determined that the basis of the formation of logistics customer service is their segmentation or differentiation. A classic logistic approach to the differentiation of customers can be considered their division using ABC-XYZ analysis. At the same time, ABC analysis is usually carried out based on the income brought by clients for a certain period of time, XYZ analysis is carried out according to the stability of relations with the client, that is, according to the number of orders placed by the client during the same period of time. We proposed our own view on the direct process of dividing customers into groups A, B and C, which is based on the calculation of the "jump in share" of customer revenues. The advantage of the proposed approach is that customers with relatively equal importance to the company cannot fall into different categories, and customers with very different values of importance to the company cannot fall into the same category. Another approach to customer differentiation based on customer profitability was also proposed and recommendations for servicing each customer group were made. Thus, the correct segmentation of customers and assessment of the potential of each segment will allow building several different service strategies aimed at increasing the company's profits.

Conclusions. The results of the analysis enabled to form groups of assortment portfolio of intangible assets that can be recognized as providing future economic benefits with a high degree of probability. For these groups, it is possible to formulate recommendations that may affect the formation of accounting mechanisms and the preparation of accounting policies. This, in turn, may affect the development strategies for budgetary research institutions and increase the efficiency of their activities.

ЗАСТОСУВАННЯ ЛОГІСТИЧНИХ МЕТОДІВ ДЛЯ ВПРОВАДЖЕННЯ CROSS-DOCKING ТЕХНОЛОГІЇ В ТРАНСПОРТНО-СКЛАДСЬКІЙ СИСТЕМІ

Abstract Introduction. The efficiency of logistics operations, the speed of processing of goods largely depend on how all parts of the logistics chain interact, how optimized business processes in the warehouse, so any company tries to constantly improve the organization of the supply process so as to deliver in the shortest possible time. term for minimum logistics costs. One of the tasks to solve the problem of supply chain imperfections is to reduce the huge number of warehousing operations during the placement of goods for long-term or short-term storage. This can be done with the help of Cross-Docking technology, which eliminates the storage phase and reduces warehousing costs. Problem statement. Today, Cross-Docking technology is mobile, technologically proven, because it is a very advanced method of processing goods. However, in order to successfully implement this technology, it is necessary to understand the concept of Cross - Docking, knowledge of the features, benefits, conditions and limitations for the implementation of this technology. That is why the question of determining the list of goods for which the introduction of this Cross - Docking technology is expedient and rational is becoming relevant. Purpose. To substantiate the definition of the list of goods for which the introduction of Cross-Docking technology is expedient and rational, using the coefficient of variation and making recommendations for their processing and methods of handling - by grouping by logistic method XYZ analysis. Methods. The XYZ analysis method was used during the work. Results. The study justified the use of the coefficient of variation to identify goods for which it is appropriate and rational to implement Cross-Docking technology, and the use of logistics method - XYZ analysis - to develop recommendations for processing and handling of certain goods. Conclusions. Based on research based on theoretical and applied aspects, the development and implementation of Cross - Docking technology is an element that simplifies business logistics and reduces the cost of its products by reducing warehouse costs, and properly organized process speeds up delivery, allows businesses to send perishable products over long distances and organize turnover even in high season. The proposed logistic method of differentiation by HYZ analysis allows to clearly identify those products that are characterized by maximum demand, high turnover, stable predictability, mass consumption, ie those products for which the recommendation is to minimize their number in warehouses, respectively - the feasibility and rationality of Cross technology - Docking. Key words: supply chain, Cross - Docking technology, one - stage Cross - Docking, two - stage Cross - Docking, XYZ - analysis, coefficient of variation, methods of grouping in XYZ - analysis, XYZ - analysis solutions.

The improved indicators applied to measure the profitable activity of a client’s portfolio in general and in terms of profit centres (business lines) enable to promptly identify a decline in the profitability of certain groups of customers,reveal its causes and offer effective solutions. The reorganization of the analytical part for client portfolio management and the implementation of ABC and XYZ analysis as well as other methodological approaches allow to monitor the dynamics of a bank’s client portfolio quality as quickly and effortlessly as possible. Analytical mechanisms for determining the quality of the bank’s client portfolio is one of the basic elements of internal audit, and this study proposes the optimal form of the internal auditor’s working document, which is best adapted to the needs of auditing business units, their quality and efficiency.

Assessment of Knowledge, Practices, and Challenges of Pharmaceuticals Inventory Control Among Pharmacy Professionals Working in Selected Public Health Facilities of West Arsi Zone, Oromia, Ethiopia.

Background:Good pharmaceutical inventory control enables health facilities (HFs) to provide complete health care by ensuring the availability of safe, effective, and affordable pharmaceuticals and related supplies of the required quality, inadequate quantity, at the required place and at all times. It boosts patients’ trust in the HFs and motivates working staff. However, it needs well-trained and skilled professionals. The aim of the current study was, therefore, assessing knowledge, practice, and challenges of pharmacy professionals conducting inventory control in selected public health facilities of West Arsi Zone, Oromia regional state for the year 2016 to 2018.Method:A mixed-methods study design was used to assess pharmacy professionals’ knowledge, skills, and challenges in applying inventory management methods. A semi-structured questionnaire was implemented for quantitative, whereas an open-ended question was employed for key informants (KIs) to explore qualitative data.Result:Ninety percent of pharmacy professionals knew about VEN analysis concepts and 70% about ABC analysis. However, none of them had a concept of FSN and XYZ analysis. Among the respondents who knew the concept, 75% had gained knowledge through formal training and 10% of them learned from on-job training. When they asked about the methods of inventory control, 60% responded as they did not hear about it. Of those who said “Yes” on being asked to mention at least 1 method of it, 80% could not able to correctly mention the methods used in inventory control. However, 44%, 62.5%, and 75% of respondents had practiced ABC, VED, and ABC-VED matrix analysis respectively. The challenges that prevented these professionals from practicing pharmaceutical inventory control in their HFs were grouped into price-related, training-related, human resource-related, and managerial-related factors.Conclusion:Inventory control is the heart of the pharmaceutical supply system. Without its healthy action, HFs’ goal attainment will not be viable. Problems of sick pharmaceutical inventory control are directly related to a lack of knowledge and appreciation of it by the concerned bodies. The current finding revealed almost all pharmacy professionals included in the study had little knowledge about how to manage their inventories. Managers’ unwillingness to cooperate and facilitate necessary resources prevented the professionals from doing inventory control.

ПРАКТИЧНІ АСПЕКТИ УПРАВЛІННЯ МАТЕРІАЛЬНИМИ ЗАПАСАМИ ТОРГІВЕЛЬНИХ ПІДПРИЄМСТВ

The article considers the methodological bases of the inventory management process and the inventory distribution system of non- food and food retail enterprises of Ukraine. In particular, it was found that the inventory management process of the investigated enterprises is based on such models and methods as the model with a fixed period of time between orders, the principles of the theory of constraints; model of the economic size of the order, method of ABC analysis; a model with a fixed period of time between orders, a method of combined ABC and XYZ analysis. In addition, it was determined that enterprises use centralized and decentralized systems in the process of distributing stocks. As a result of the analysis, a number of advantages and disadvantages of the mentioned processes were highlighted. In particular, the key advantages of the inventory management process of trading enterprises include: taking into account the factor of seasonality and the location of stores; weekly tracking of store sales intensity; the possibility of taking into account the demand of each chain store; use of direct delivery services from suppliers, which allows to take into account perishable categories of goods; use of EDI electronic data exchange, etc. The main shortcomings include: untimely response of managers to possible unexpected circumstances of the external environment, which leads to an excess or shortage of goods in stores; unreasonableness of changes in the stock buffer when making decisions about the amount of material stock; insufficient validity of the calculation of the insurance reserve, lack of a clear distribution of the size of the insurance reserve by groups; the difficulty of promptly and fully resolving issues related to the purchase of goods, etc. Prospects for further research are the development of proposals for solving the identified problems, in particular, recommendations for optimizing the process of inventory management of trading enterprises.

THE ROLE OF LOGISTICS ANALYSIS METHODS IN THE ENTERPRISE RESOURCE MANAGEMENT SYSTEM

The article discusses the role of logistic analysis methods in the enterprise resource management system. The author refers to modern problems of resource management, the main indicators used in the management of inventories, the methods used in the management of inventories of enterprises, the main indicators used to assess the effectiveness of the chosen policy in inventory management, etc. issues are researched. The goals of the individual units of the enterprise often contradict each other. The goals of various divisions of the enterprise for the use of resources are contradictory and the solution of this problem is one of the main tasks of logistic resource management. The author considers that the reserve policy is somehow determined by a significant influence on the structure of the enterprise, concessions between risks and costs, liquidity and turnover are determined. The second path is more difficult because management requires skills in resource management and management accounting. A sequence of simplest steps along the way is recommended. In most cases, resource management in a material nomenclature is so extensive that it is simply impossible to analyze and modernize every situation in the nomenclature in detail. To simplify this problem, the article conducts an AVS-analysis of the entire range of materials and divides the resources into three groups. Here, indicates A- a high value of volume, V- moderate value of volume and S- low value of volume. When the AVS analysis is combined with the XYZ analysis, the enterprise effectively manages the acquisition of materials. The article substantiates and proves the method of conducting a comprehensive analysis of AVS and XYZ. XYZ-analysis allows the enterprise to carry out the classification of these resources together and depends on the accuracy of forecasting changes in their needs. XYZ — grouping of resources in the analysis is carried out in the order of increasing coefficient of variation. The author notes that the proper optimization of material resources allows you to minimize costs, increase quality and efficiency of production, and ultimately increase the profitability of capital.

Segmentation of store customers to increase sales using ABC-XYZ-analysis and clustering methods

To manage interaction with customers, it is necessary to divide them into groups depending on their buying activity. For this, the author uses segmentation (ABC and XYZ analysis) and clustering (K-means, X-means, Expectation-Maximization) methods in the intelligent software platform RapidMiner Studio. For calculations, data on sales of a store selling auto parts are used. The author notes such features of the trade in truck parts as the seasonality of maintenance and the irregularity of purchases in comparison to general-purpose goods, which affect the choice of the time interval in sales data. The ABC-XY-analysis showed that it is better to use only the results of the ABC analysis, taking into account the volume of purchases, and the XYZ-analysis based on the analysis of the frequency of purchases gives the wrong result due to the seasonality of purchases. The results of clustering using K-means and X-means methods are almost the same, but their disadvantage is that 95% of customers are classified as the cluster with the worst purchasing activity, and this separation cannot be used for marketing purposes. The Expectation-Maximization method gave the best division of the client base into clusters.

Intelligent automation system of the railway company’s purchasing activity based on artificial neural networks

A person is responsible for quality control of the purchase forecast of commercial enterprises, which entails a number of certain consequences. In this regard, we decided to create an intelligent system that will determine the quality of the forecast. Such a system will be a human assistant in deciding on the quality of the forecast. The system will also be able, if necessary, to indicate the necessary adjustments for its forecasting method. As part of this work, a software product will be created that will determine the quality of the created trade procurement plan, and, if necessary, help the user adjust the forecasting method used by the outlet. The aim of the work is to create an intelligent procurement system that will generate its forecast using a neural network, and then determine the forecast error using XYZ analysis.

Sustainable Development of Rural Territories in the Conditions of Territorial-Production Localization: Methodological Aspect

Sustainable development of rural territories in the conditions of territorial-production localization: methodological aspect. The issues of sustainable development of territories are given great attention. However, in most of the works, general statements of problems, concepts and principles prevail: an analysis of the sustainable development of territories, a comparative analysis of the development of various socio-economic systems in the regions and other general problems of the country’s social and economic development. The insufficient depth of elaboration of conceptual provisions limits the practical value based on the recommendations existing in theories, aimed mainly at the sphere of macroeconomic regulation. This makes it necessary to further study the issues of sustainable development of rural territories. One of the promising areas is production and territorial localization. The local market is a market of a municipality of a region of the Russian Federation or part thereof, representing an economic system based on the principles of limited resources, characterized by the predominance of locally produced goods, unified logistics and a zone of price influence. Development is a process of qualitative and quantitative changes that enhance and improve the current state of the system, i.e. the process of transition from the old, simple to the new, more complex, higher, quantitative and qualitative state of the system. The concept of "development" is closely related to "management." When these concepts are correlated, the relation of the part to the whole is traced. The assessment of the level of development and location of local markets in rural areas was carried out on the basis of the adjusted XYZ analysis, which allowed us to predict development prospects.

Logistics model for selecting road sections of a mining enterprise for equipping them with automated traffic control tools

The proposed model allows us to determine the sections and objects on the roads of mining enterprises that operate in the most intensive mode, in order to equip them with automated traffic control tools. The model is based on the logistic method of ABC and XYZ analysis, which allows determining such objects and areas with sufficient accuracy. In addition, the scientific novelty of this model is the choice of technical means not by two parameters, as in the classical logistics model, but by three. In addition, this model offers to determine the optimal number of technical means of traffic control, taking into account their cost and the required reliability. When optimizing the number of technical means of traffic control on the roads of mining enterprises, a linear programming model was used that minimizes the target function of total costs, taking into account the required reliability of technical means, while limiting their number used in performing traffic control tasks. The original distribution of technical means for the tasks of traffic control on the roads of mining enterprises is proposed.
