Ranking Method for the Importance of Aircraft Damage Spare Parts

Whether war wounded aircraft can be repaired quickly and effectively determines the operational capability of aircraft in the war environment. In order to ensure the combat readiness and continuous strength of the aircraft, it is necessary to scientifically determine the spare parts requirement of the war wounded aircraft. In this paper, a ranking method for the importance of combat aircraft damage spare parts is established. Firstly, the model of aircraft combat spare parts is established to determine the type of combat spare parts to be ranked. Secondly, the kill probability and survival probability of aircraft components in one mission are analyzed and determined. Thirdly, the independent existence state of aircraft and the occurrence probability and system performance of each independent state are determined. Finally, Griffith degree of importance of aircraft residual lethal parts was calculated and the order of war damage spare parts was conducted.
