Problems solved by technology
Although the existing technology can realize the evaluation of the economic feasibility of the self-purchased aviation material guarantee and the flight-hour aviation material sharing repair service, but due to the lack of the necessary self-purchased aviation material repair cost calculation model, the above method will not be able to realize the self-purchased aircraft. Therefore, it is impossible to accurately evaluate the economic feasibility of self-purchased aviation material support and flight hour aviation material sharing repair service

Embodiment Construction
[0040] Embodiment provides a kind of economic feasibility evaluation model of Airbus aircraft aviation material support mode, comprises the following steps:
[0041] 1. Obtain aviation material parameters, which include calculation cycle, calculation base year, number of aircraft, installed number, annual flight hours, self-repair cost rate, unplanned replacement time, modification and upgrade rate, scrap rate, residual value rate, procurement Period, repair period, transportation period, discount rate, price fluctuation rate, aviation material catalog price, flight hour aviation material shared warranty service rate;
[0042] 2. Calculate the net present value of self-purchased aviation materials guarantee
[0043] (1) Calculate and predict the cost of aviation spare parts
[0044] Based on the number of aircraft, flight hours, installed capacity, and unplanned replacement time, calculate the annual demand for aviation material turnover parts Dann:
[0045]
[0046] Amon...

The invention relates to the field of aviation materials, discloses an economic feasibility evaluation model of an aircraft material support mode, and improves the accuracy of the economic feasibility evaluation of the aircraft material support mode. The present invention introduces reliability data based on the unplanned replacement time of aviation materials, and accurately calculates the average value of aviation materials for a single replacement, which is more in line with the reality of airline aircraft maintenance aircraft material repair cost prediction, and can To avoid the lack of data basis for aircraft material repair and the inability to accurately predict the repair cost of self-purchased aviation material support, improve the accuracy of the economic feasibility evaluation of self-purchased aviation material support and flight-hour aviation material sharing repair services. The invention is applicable to the economic feasibility evaluation of the aviation material guarantee mode of the Airbus aircraft.
Description
technical field [0001] The invention relates to the field of aviation materials, in particular to an economic feasibility evaluation model of an aircraft material guarantee mode. Background technique [0002] Aircraft material, short for aviation material, refers to the materials required for aircraft maintenance; flight hour air material sharing and repair service is an aviation material guarantee model that pays air material leasing fee, sharing fee and repair fee according to the flight hour of the aircraft. [0003] With the rapid development of China's civil air transport industry, the number of airlines' aircraft has increased rapidly, and the demand for aviation materials and spare parts related to aircraft maintenance has also increased greatly, which has put a lot of pressure on the maintenance guarantee and economic benefits of airlines. At present, the international In the field of civil aviation aircraft maintenance, the aviation material guarantee mode is mainly...
