摘　　要：针对可修系统难以准确评定其运行过程中的可靠性状态,把可修系统的可靠性评估分为运行可靠性和性能参数可靠性。对于不同维修阶段的运行可靠性,用故障统计的方法评价其可靠性;对于性能参数可靠性,通过构建可测参数的可靠性退化模型进行评价。以柴油机喷油系统可靠性综合评估为实验研究对象,结果表明,文中所提供的方法很好地表达出可修系统任意时刻的可靠性状态,而且为类似可修系统的可靠性评估提供参考。In this paper, repairable system reliability assessment bases on operation reliability and performance reliability, and thus makes it possible to accurately evaluate the reliability status in the process of operation. This paper applies failure statistics to the operation reliability in different stages of maintenance and establishes reliability degradation model for measurable parameters. The paper considers diesel fuel injection system which is used in the study of reliability comprehensive evaluation, and the results show that the method proposed here possesses higher application value in the reliability evaluation.
