Agricultural production is characterized by the seasonality of technological operations, the ability to carry out which in a strictly set time depends on many factors of the external environment and the reliability of agricultural machinery. The harvest of grain and other crops by combines occupies a special place among field works. Operative carrying out of these works without down time of the grain-harvesting techniques provides the minimum losses of the agricultural production. It is possible to minimize downtime of harvesters due to technical reasons if the enterprise has at its warehouse a seasonal reserve of spare parts that are in great demand during harvesting works. The methods of reserve calculation should consider not only the reliability of some harvester parts, but the cost damage of harvester downtime and extra costs of spare parts purchase and storage. With such a large number of external factors, traditional methods are difficult to calculate. With the development of computer technology, the methods of evolutionary calculations have been widely used, in particular, genetic algorithms that allow creating self-adjusting models capable of analysing the examined indicators for the past years, reacting to the changes of current external conditions, and making short-term forecasts of the values of optimised variables. The purpose of this research was to develop a genetic algorithm and software that will enable us to meet the seasonal demand for spare parts from combine harvesters. The software allowed us to identify 66 of the most in-demand items out of 2800 warehouse items that should be reserved for the season of harvesting crops. The efficiency of the proposed solutions is proved by the reduction of the downtime of combines due to technical reasons by 37% and the increase of their shift productivity by 11.4%; at the same time, the combine reliability index, the operational readiness factor, increases by 4.38%.

The possibility of using ABC and XYZ analysis to systematize customers by degree of reliability by group positions has been presented. The approach of vector work with customers has been proposed, which implies the assessment of receivables by means of their ranking by key criteria, identifying those, who are less exposed to the risk of default on money. The basis for the implementation of the formulated information base can be used when building an evaluation card of buyers - debtors for taking specific measures for business development.
данное исследование посвящено разработке и оценке системы управления запасами, включая алгоритмы оптимизации складских процессов. В работе применен комплексный подход к сбору данных, сочетающий традиционное анкетирование и онлайн-опросы, с участием 50 респондентов. Анализ результатов выявил сильные стороны системы, такие как модульность и потенциал повторного использования компонентов, а также области для улучшения, включая анализируемость, модифицируемость и тестируемость. На основе полученных данных предложен ряд рекомендаций по совершенствованию системы, включая внедрение автоматической генерации отчетов, разработку гибких алгоритмов сортировки, интеграцию технологий машинного обучения, создание модуля визуализации данных и разработку мобильного приложения. Дополнительно рассмотрены возможности коллаборативного прогнозирования и расширенной интеграции с корпоративными системами. Исследование основано на структурированных интервью, обеспечивающих глубокий анализ качественных данных. Результаты работы направлены на повышение эффективности управления запасами и могут служить основой для дальнейших исследований в этой области. this research is dedicated to the development and evaluation of algorithms and software solutions for efficient inventory management. The study employs a comprehensive approach to data collection, including traditional surveys and online questionnaires involving 50 respondents. The developed algorithm covers all stages of inventory management, including data collection and analysis, inventory classification using ABC and XYZ methods, and order volume optimization using the EOQ model. Analysis of the results revealed the system's strengths, such as modularity and potential for component reuse, as well as areas for improvement. Based on the data obtained, recommendations for system enhancement are proposed, including the implementation of automatic report generation, development of flexible sorting algorithms, integration of machine learning technologies, and the creation of a mobile application. The research results aim to improve inventory management efficiency and can serve as a basis for further research in this field.
