ANALYTICAL JUSTIFICATIONS FOR THE DEVELOPMENT OF A SIMULATION MODEL OF MAINTENANCE OF AVIATION GROUND EQUIPMENT TAKING INTO ACCOUNT THE NEED FOR SPARE PARTS AND MATERIALS

Abstract

The article considers the issues of improving the maintenance system of modern special equipment at airports through the optimization of processes related to ensuring its operation with spare parts and materials. It was shown that the efficiency of a modern airport’s operations largely depends on the quality of management at all levels, including the organization of the proper use of special equipment and machinery. The quality of these processes significantly depends on the availability of accurate information corresponding to the condition and development trends of a specific airport, as well as methodological support, in particular for processes related to the maintenance of aviation ground equipment. The conducted research considers the framework of addressing the global challenge of risk management in the aviation industry. For this purpose, a model of the functioning of the airport special transport service’s spare parts and materials supply system was proposed. Additionally, an objective function was introduced, and the most significant constraints in achieving the set goal were analyzed. In particular, the main patterns that determine the consumption and variation in the consumption of material resources used during the maintenance of aviation ground equipment were studied: changes over time in operating conditions; changes over time in the intensity of operation; the influence of operating conditions on the resource of parts replaced based on condition; changes over time in the consumption of parts replaced based on condition; changes over time in the amount of maintenance work by type and level; changes over time in the consumption of materials replaced based on operating time; and the influence of operational intensity and the frequency of different forms of maintenance on the number of maintenance operations by type and level. The developed simulation model of maintenance demand for aviation ground equipment allowed for the improvement of a generalized model for the operation of special equipment and machinery at a modern airport, regardless of the condition and size of the equipment fleet.
