利用设备变母体变环境数据的系统可靠性综合评估

 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。

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

Varied population-environment data which come from the testing phases of component's developing course are recommended to be used by Lindstrom-Madden method for integrated evaluation of system reliability. First,it is discussed how to use varied environment data to evaluate reliabilities of varied population component and unvaried population component. Then,the improved L-M method is presented based on the above process. The method can be used to evaluate the system reliability. 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.
