A prediction method of aeronautics equipment spare parts requirement considering spare part sharing was proposed aimed at reducing high spare parts sharing proportion of similar types of aeronautics equipment. Firstly, according to the structural similarity, the spare parts were divided into special spare parts and shared spare parts. Then, the spare parts requirement under the condition of daily support and wartime support was further considered. With the constraint of spare parts support probability, the requirement prediction model of special spare parts and shared spare parts were constructed respectively on the basic assumption that the daily failure obeyed the exponential distribution and the battle damage-oriented obeyed the binomial distribution. Finally, based on a certain kind of avionics system, the validity and effectiveness of the proposed model were verified.
