摘　　要：传统的备件保障概率模型表达的是它在规定保障周期期末的备件保障概率,它低于保障周期内任意时刻的备件保障概率,因此用它作为参数表征具有概率平均特征的战备完好率或使用可用度中是不适宜的,计算得到的使用可用度或战备完好率的结果偏向保守,后果是增加了备件积压的风险。文章首次提出了在规定保障周期内备件平均保障概率的概念,备件平均保障概率使各站点备件配置数量更加符合实际,降低了寿命周期的费用。It prescribes the probability of the end of specificial support cycle in the traditional spare support probability（SSP） model, but it isn＇t represent the average SSP character of the Weapon integrity or availability, for it＇s less than the probability at the any time in the cycle, and its result is more reserved, which increases the risk of the spare overstock. It gives the average SSP model at the end of speeifieal support cycle in this article, which makes the spare distribute more fit in every depot, and reduces the life cycle cost.
