Abstract

The proposed structure of the CORT /system for ensuring the operability of the equipment/ foresees various possibilities for serving users at the farm, district and regional level. The parameters for the model levels are adjusted taking into account the main real indicators of the area served by one or another level of the system. These indicators include the volume of mechanized work, the intensity of demand for service and repair of parts, assemblies and aggregates, as well as the qualifications of machine operators in the service area. The concepts of models at the farm and region level are presented, for which the CORT parameters are calculated, and then the transition to the actual levels (districts, farms) is presented through coefficients that take into account the specifics of the service area. The proposed normative-computational method for determining the parameters is applied to a fictitious area.

Keywords
