Method of Reliability Increasing Based on Spare Parts Optimization for Telecommunication Equipment

Telecommunication equipment in civil aviation is used for timely transmission of messages and useful information. This equipment performs the functions of establishing communication between the air traffic controller and the aircraft, ensuring the production activities of the airport or operating companies. Ensuring the reliability of the functioning of telecommunication equipment is a complex and sophisticated task, as it directly affects the risks of air navigation services, including the risks of catastrophic situation occurrence. Since modern equipment is developed according to the block and module principle, one of the ways to solve this problem is to plan the optimal quantity of spare parts for certain blocks, modules, nodes, and others. This optimization is usually multi-criteria and is performed on the basis of data on equipment failures and faults, available operating costs, requirements for recovery time. Sometimes the task is also complicated by the need for logistical analysis of spare part transportation. Taking into account the above, this paper is devoted to the development of a model of the procedure’s performance of serviceability recovery for the aviation telecommunication equipment in cases of available spare parts and the analysis of the efficiency of the proposed model. The paper contains both analytical calculations and the results of statistical modeling.
