AVIONICS TECHNICAL OPERATION SYSTEM AND SCIENTIFIC BASIS FOR ITS FORMATION

Abstract

Avionics Technical Operation System (ATOS) is a set of objects and subjects of technical operation such as avionics itself as an object, personnel, carrying out procedures and organizing technical operation processes, as a subject, hardware and software for technical operation and maintenance and repair programs as well. ATOS is subordinated to Aircraft Technical Operation System (A/C TOS), which determines its goal and restrictions. The quality of ATOS is characterized by a set of properties that determine its ability to meet the maximum economic efficiency of the needs of A/C TOS, while ensuring the required levels of avionics reliability and availability. Avionics Maintenance System, Avionics Repair System and Avionics Operation Test System are the systems of a lower level of hierarchy in relation to ATOS, which defines the goals and restrictions of these subsystems. Based on the analysis of ATOS as an object of research, analysis of mathematical modeling as a research apparatus and the developed hierarchy of efficiency criteria for ATOS and the systems interacting with it, we formulate the overall task of the research as follows. On the set of parameters of ATOS, we have to find such parameter values that the system costs in process of technical operation reach the minimum when all the required tasks are fulfilled and all the restrictions on the system own parameters and indicators of its technical efficiency are met. To solve the general task it is necessary to solve successfully a lot of tasks, formulated in this article. The theoretical results obtained during the research can serve as a scientific basis for solving practical problems of the formation and improvement of ATOS. Formation and improvement of ATOS is a long and laborious process, requiring the usage of the most advanced mathematical methods. Thus, mathematical modeling of ATOS should significantly reduce the costs of the system's formation, since it allows us to introduce certain adjustments in the early stages of its operation on the basis of available and constantly updated information.
