    The parameters of an agricultural machinery workshop with an unlimited incoming flow of repair-service requests have been studied. As a result of each research experiment and the obtained change values of the calculated service parameters, the character of their change depending on the number of channels serving the tractors was calculated. The change values of the calculated parameters depending on the number of service channels are reflected in a table and graphically presented.

    With the help of the parameters characterizing the work of the service for mobile equipment, a quantitative assessment of its activity can be made. Therefore, their knowledge and determination are of particular importance. In order to optimize the parameters of the service, we formalize its operation as a mass service system (MSS).
    In the stationary state of the service, the formulas for determining its individual parameters are derived.

    The article examines the single and complex indicators of the operational reliability of agricultural machinery (tractors and combines) operating in the special soil-climatic and dynamic conditions of Georgia, highlights the least reliable units and parts that require constructive improvement.
    As a result of research, according to the methodology of probabilistic and statistical modeling developed by us, integral and differential distribution functions of reliability indicators were obtained, their general characteristics were determined, as well as mathematical models and the values of reliability indicators were determined taking into account the distribution law. The adequacy of the probabilistic-statistical models was tested using the Pearson and Kolmogorov goodness-of-fit tests.
    As a result of theoretical and experimental studies, characteristic malfunctions and failures of the main units of foreign ag ricultural equipment operating in Georgia have been established, and constructive and technological measures to improve reliability have been developed.

    The structure of the system for supplying spare parts for tractors and self-propelled agricultural equipment has been examined. A centralized system of continuous inventory replenishment has been investigated and the influence of the basic parameters of the supply system on the probabilities of refusal of execution of requests is determined.

    It has been shown that the most significant impact on performance indicators of the spare parts supply system is the demand flow intensity.

    Производствените процеси в растениевъдството се осъществяват при взаимодействието между организационно свързани съвкупности от мобилни, стационарни и обслужващи единици. Ефективното използуване на скъпоструващата и високопроизводителна прибираща техника е пряко свързано със синхронизацията на работата им .

    В разработката е предложен математически модел за оптимизиране на взаимодействието между производсвените и обслужващите машини в съвместната им работа при прибиране на зърнено-житни култури.

    За оптимизация на съотношението между основните и обслужващи машини е използван критерият минимум на загубите от престои.
