摘要
在鱼雷贮存失效时间数据具有删失性的情况下,科学合理地评估鱼雷贮存可靠性具有重要的现实意义。根据鱼雷贮存期间的区间删失数据,由生存分析理论的turnbull估计与最大似然估计方法,运用MATLAB软件编制相应的计算程序,分别对某批次鱼雷的贮存可靠性进行了估计。实例计算表明,应用生存分析理论能够有效解决贮存失效时间删失条件下鱼雷贮存可靠性评估问题,并得到更加合理的评估结果。
In the case of storage failure time data having the censoring characteristic, it is of significance to scientifically and rationally assess torpedo storage reliability. In this study, on the basis of the censored data of torpedo storage time, the storage reliability of the torpedoes in a batch is assessed respectively by using the turnbull estimation method and the maximum likelihood estimation method in survival analysis theory, and the corresponding calculation program is coded by the software MATLAB. Calculation results of an example show that the survival analysis theory is effective for as- sessment of torpedo storage reliability in the case of storage failure time data censoring, and can obtain more reasonable assessment.
