飞机战伤备件需求量确定方法

 发展了一种飞机战伤备件需求量预测的理论方法。首先分析了飞机基本功能项目的损伤级别，讨论其对飞机存在状态的影响，总结出战伤备件的类型为遭受非致命损伤的飞机基本功能项目。然后，分析飞机存在状态以及对应的备件需求向量，提出飞机一次出动备件的需求概率为飞机基本功能项目损伤且飞机生存的联合概率。最后，运用马尔可夫链法，解决了战伤备件需求概率的计算问题，得到了基于二项分布的战伤备件需求量。算例和结果分析表明该方法合理、可行，对科学地确定飞机战伤备件数量具有指导意义。

Ascertaining of Spares Requirements for Aircraft Battle Damage

A theoretical model is developed to predict the spares requirements for aircraft battle damage.First,a review is made of the damage levels of basic functional items of the aircraft and the effect of damage levels on aircraft existence,and then a summary is reached that the types of spares are the basic functional items which suffer uncritical damage.Second,by analyzing aircraft existent states and the corresponding spares requirement vectors,this article holds that the probability of the spares required in ...
