基于层次分析法的某型号控制系统可靠性指标分配

摘要

研究了系统可靠性分配理论，将层次分析理论引入系统可靠性指标分配领域，形成新的可靠性指标分配方法。以某型号控制系统为例，建立了系统层次分析模型，利用层次分析法确定了系统各构成的权重，以及可靠性指标分配。计算结果表明，基于层次分析法的系统可靠性指标分配方法能够更好地综合技术成熟性、继承性、系统复杂性等因素，更客观、系统地进行可靠性指标分配。%This paper studies the system reliability allocation theory .The theory of analytic hierarchy is brought into the field of system reliability allocation , and a new reliability allocation method is formed. Taking a type of control system as an example,a system analytic hierarchy model is established ,and the weight of the composition of system and the reliability allocation are determined by analytic hierarchy process(AHP).The results show that the allocation method based on AHP can synthesize technology ma -turity,inheritance and system complexity more correctly ,and can realize reliability allocation more objec-tively and more systematically.
