多状态鱼雷可靠性的评定方法

为了客观、真实评价鱼雷的可靠性水平,为鱼雷试验考核和使用提供依据,在分析鱼雷试验的多状态特点和鱼雷可靠性的二项分布评定方法的基础上,运用模糊性概率的理论和方法,用可接受的合格度之和代替试验成功数,建立了多状态下鱼雷可靠性点估计和置信下限的评定方法,将成败型鱼雷可靠度的评定向多状态拓展。此方法简单易行,便于实际运用,多状态可靠性评定方法的运用和实践,有利于推进鱼雷可靠性的发展。

Reliability Estimation Method of Torpedo in Multimode Condition

To accurately evaluate the reliability of a torpedo and provide evidence for test and usage,this paper presents a reliability estimation method and the lower confidence limit for torpedo in multimode condition by analyzing the mul-timode feature and binomial distribution of torpedo test.The fuzzy statistics theory and method are used in this study to substitute the sum of acceptable quality levels for successful test number.
