摘要
针对目前任务可靠性尚无工程验证的现状,在基于现有测试性试验工程应用的基础上提出了一个任务可靠性验证方法。阐述了该方法的理论,分析了需评估的参数,介绍了验证的流程,给出了数据收集和处理的方法,并根据收集处理的结果给出了任务可靠性的评估方法,包括点估计、置信下限估计和置信区间估计。在基本可靠性评估的基础上综合测试性的数据,实现了对任务可靠性的有效评估,为任务可靠性的考核提供了依据。
Aiming at there is no method to validate the mission reliability, introduced a way to validate mission reliability base on testability test engineering application. Emphasized the theory of this method, analyzed need assessment parameters, introduced the validation flow, provided the method of data collecting and processing. According to the results of processed data, the mission reliability evaluation method was put forward, including point estimation, lower confidence limits estimation, confidence interval estimation. The research integrated testability data based on basic reliability assessment, realized the effective assessment of mission reliability. It can provide evidence for validating the mission reliability.
