CONCEPTUAL MODEL OF OPERATIONAL CONTROL OF MACHINES AND EQUIPMENT COMPLEX IN CROP PRODUCTION
The article deals with the development of a conceptual data model (ER-model), which is invariant to the database structure and implements the method of determining the ultimate throughput of a forage harvester. This method allows to determine the values needed to justify the rational acquisition and efficient use of interactive machines within technological complexes. The designed conceptual model is of practical importance and may be used in the future to develop a database that implements the above method.
