System approach to research processes of technological adjustment of machine and tractor units

A substantive interpretation of the main categories of the system approach is formulated in relation to the semantics of the operation of mobile agricultural units from the standpoint of ensuring the technological reliability of the production of field mechanized work by improving the methods and means of measuring control of the state of machine and tractor units and evaluating the parameters of functional diagnostics under shift time conditions. A structural diagram of the systemic image of the production of field mechanized work is proposed, which makes it possible to clarify the hierarchical levels of movement of concepts in the field of managing the state of a complex technical system during the operation period, to highlight the object of research and establish its system elements and connections with the operating environment. The business logic of the implementation of the basic operations of the system of technological adjustment of machine-tractor units to ensure the quality of the technological operation when used for its intended purpose is presented. The theoretical significance of the work is associated with the development of a systematic understanding of the main objects of the processes of machine use in agriculture. The applied and practical significance of the work is confirmed by new technical solutions implemented in projects and organizational and technical documents of an industry scale. The results of the work can be useful both for researchers of the processes of machine-use in agriculture, and for practitioners-subjects of small and medium-sized agribusiness, as well as in organizing the transfer of knowledge of the agro-engineering direction to specialists in agricultural production.
