Information System of Machines and Tractors Fleet Technical Service

Abstract

providing technical services also requires providing quality assurance of these services. Results of leading experts’ research in this field is not always available for engineers of agricultural companies, that is why there is need for development of a customer quality assessment method or a method of quality assurance by technical services suppliers. Project of machines and tractor fleet technical service system which included an assembly of interrelated and interdependent elements – processes running in machines, technologies of technical service, performers of technical service – is defined and directed by the aim of technical service which consists in maintaining operability of agricultural equipment, allows to create a method of quality assessment. The quality index represents multiplication of partial factors which take into consideration degree of correspondence of performed volume of works to the required volume, degree of correspondence of maintenance intervals to the required intervals, degree of conformity of repair and maintenance technologies to processes in subsystems; sufficiency of performers competence for implementation of repair and maintenance; sufficiency of range of works potentially carried out by technical service performers for maintenance of a certain types of machine- and tractor aggregates. The degree of correspondence of intervals can be ensured by meeting the requirements of standards and technical documentation. The volume of technical services works can be provided by involving a group of technical service performers. A variant of technical service performers’ competence assessment method is suggested. Along with that an information system of technical service is developed which allows to state interdependencies determining quality of technical service.
