GRAPHICAL MODELS OF THE AIRCRAFT MAINTENANCE PROCESS

The aircraft maintenance is realized by a rapid sequence of maintenance organizational and technical states, its research and analysis are carried out by statistical methods. The maintenance process concludes aircraft technical states connected with the objective patterns of technical qualities changes of the aircraft as a maintenance object and organizational states which determine the subjective organization and planning process of aircraft using. The objective maintenance process is realized in Maintenance and Repair System which does not include maintenance organization and planning and is a set of related elements: aircraft, Maintenance and Repair measures, executors and documentation that sets rules of their interaction for maintaining of the aircraft reliability and readiness for flight. The aircraft organizational and technical states are considered, their characteristics and heuristic estimates of connection in knots and arcs of graphs and of aircraft organizational states during regular maintenance and at technical state failure are given. It is shown that in real conditions of aircraft maintenance, planned aircraft technical state control and maintenance control through it, is only defined by Maintenance and Repair conditions at a given Maintenance and Repair type and form structures, and correspondingly by setting principles of Maintenance and Repair work types to the execution, due to maintenance, by aircraft and all its units maintenance and reconstruction strategies. The realization of planned Maintenance and Repair process determines the one of the constant maintenance component. The proposed graphical models allow to reveal quantitative correlations between graph knots to improve maintenance processes by statistical research methods, what reduces manning, timetable and expenses for providing safe civil aviation aircraft maintenance.
