航空装备系统改进时的可用度分配方法

Method of availability allocation in upgrading aviation equipments

提出了用于系统改进时可用度分配的指标确定方法。这种方法主要是把系统可用度分配给分系统,通过系统可用度与分系统可用度关系分析,建立了系统与分系统可用度之间的数学模型。用层次分析法确定了分系统的重要度,通过提高较小的分系统可用度,保证满足系统可用度增长的目的。最后通过实例给出了具体计算步骤。

An availability allocation method that is applicable in upgrading systems is presented. The main aim of the method is allocation that in system availability to sub-system. The method is a mathematical model between overall system availability and availability of separate sub-systems by analysis of system availability and sub-system availability. Importance of separate sub-systems is defined by analytic hierarchy process. Requirements allocation ensures an increase in system availability to a required level with minimal sub-system changes. A computation method is presented by an example at last.
