ASPECTS OF EXPERT SYSTEM OF ENGINEERING MANAGEMENT OF TECHNICAL CONDITION OF GRAIN HARVESTERS

Engineering management of the technical condition of combine harvesters is mainly entrusted to the combine operator or service team, for which the greatest difficulty is related to information and intellectual aspects, which determine the high requirements for operator qualification, to the level of technical diagnostic tools. The solution of manually littlestudied and complex problems of technical diagnostics of combine harvesters encounters natural difficulties associated with the need for heuristic processing of large amounts of information and logical analysis of complex interconnected processes. The value of these factors is exacerbated by the rapidity of the harvesting process, the high risk of erroneous or delayed assessment of the technical condition of the combine, which leads to significant crop losses and does not allow to obtain a possible effect. Thus, ensuring high quality maintenance of the combine harvester largely depends on the professional competence of staff, which is a deep knowledge of the design of the machine and its subsystems: mechanical systems, hydraulics, electrical equipment.
