Modeling of technical service units taking into account the load of the tractor engine

Organization of work in the crop cultivation must ensure strict observance of optimal agrotechnical terms of work and their rational duration. In this regard, machine-tractor units need to perform certain amounts of work on a daily basis. With optimal availability of equipment, the solution of this problem does not cause difficulties. At a time when the machinery and tractor fleet of agricultural enterprises has more than half developed its amortization period. The load on the tractor exceeds the standard three or more times. This problem may seem unsolvable and the solution is not obvious. According to the existing mathematical model of technical service, the required amount of maintenance work can be performed by a group of performers for a certain period of time that is two to three times less than the standard. The frequency of service should be equal to or deviate from the standard within acceptable limits. Due to this, a minimum level of downtime of tractors will be provided to eliminate the consequences of failures...
