Abstract

With the rapid development of the aviation industry, airlines of various countries have to store a large amount of aviation materials at airports and maintenance bases in order to ensure the normal operation of flights. However, this has resulted in a backlog of aircraft inventory, which undoubtedly imposes significant depreciation and administrative costs on airlines. In this paper, we address the aircraft material allocation problem faced by airlines under the multi-base and multi-tier aircraft material inventory distribution model, and mathematically abstract the factors affecting the allocation of aircraft material. By constructing a mathematical optimization model with the lowest total avionics management cost of the whole inventory system as the objective function, and the avionics guarantee rate and downtime as the constraints, we aim to optimize the number of avionics allocation of the avionics base as a whole, in order to reduce the amount of avionics inventory, so as to achieve the purpose of reducing the inventory cost. Taking China Eastern Airlines, one of the three major airlines in China, the high-priced turnover parts of aviation materials as the research object, the mathematical simulation model is prepared using Matlab software. It confirms that the two-level inventory avionics management model proposed in this paper has certain advantages and provides a new solution for airlines in finding the balance between avionics protection and avionics management cost.
