Ground air navigation devices, which include ground equipment for radio engineering support of flights, play an important role in the process of flights' safety and regularity providing. The operational efficiency of ground air navigation equipment in the civil aviation is ensured by the system of their operation. The components of the operation system are equipment, regulatory documentation, personnel, means for operation, which include facilities, technological devices, the main and additional technological processes and procedures, etc. The main process in the operation system is intended use of equipment, the additional processes are maintenance, repair, continuation of life service, monitoring, statistical data processing, and others.
A promising direction for improving the operation system may be the utilization of the complex for supporting the efficiency of the operation system using the principles and provisions of ICAO and Eurocontrol regulatory documentation, international quality standards, etc. The tasks of the efficiency support complex include assessing the compliance of operation system parameters with the established requirements through the use of subsystems of collection, processing, decision making, formation of control actions and their implementation based on information on the condition of structural elements of operation system, including the current condition of ground air navigation equipment. In the general case, this complex should be created on the basis of widespread use of information technology for operational data processing, principles of adaptation, systems approach, elements of artificial intelligence to automate management decision-making procedures in the operation system for ground air navigation equipment.
This thesis concentrates on the methodology of statistical data processing in the operation systems for ground air navigation equipment. Such methodology includes methods for detecting deterioration of technical condition by analyzing the monitoring parameters trends for ground air navigation equipment and components of their operation systems, estimation methods of reliability indicators after changepoint, methods of improving maintenance policies with preventive thresholds, which were substantiated by the relevant theorems in the framework of the use of the new indicator for efficiency of those operation systems. The methodology generally provides an opportunity to improve the efficiency of functioning of ground air navigation equipment and their operation system by creating and implementing timely and correct preventive and corrective actions.
With the help of the developed methodology, designers and engineers of ground air navigation equipment, as well as specialists in the field of development and improvement of operation systems can solve the problem of minimizing operating costs by: making timely and correct decisions to identify deterioration in the monitoring parameters and reliability indicators trends for ground air navigation equipment and systems of their operation; use of advanced maintenance strategies based on a system of preventive thresholds and application of the principles of adaptability as a component of artificial intelligence.
The obtained scientific results should be used during the design and improvement of operation system for ground air navigation equipment, as well as in the educational process.
