利用设备变母体变环境数据的系统可靠性综合评估

Integrated Evaluation of System Reliability Using Component's Varied Population-Environment Data

提出在系统可靠性综合评估L M法中可以利用设备研制过程中变母体变环境数据。首先论述了设备研制阶段变母体和不变母体情况下,利用设备不同环境数据对设备可靠性进行综合评估,在此基础上,给出了系统评估L M法的结论。实例计算表明,由于用于设备可靠性评估的数据量的增加,评估的准确性大大提高。

Varied population-environment data which come from the testing phases of component developing course are recommended to be used by Lindstrom-Madden (L-M) method for integrated evaluation of system reliability. How to use varied environment data to evaluate reliabilities of varied population component and unvaried population component is described. Then, the improved L-M method is presented. An engineering instance of evaluation shows that the result of reliability is more accurate because of the increased samples which are used for evaluation of component reliability.
