小子样鱼雷装载失效率与工作失效率关系

Relationship between Stowage Failure Rate and Work Failure Rate of Torpedo based on Small Sample System

鱼雷装载试验信息很少,用数理统计方法评估其装载失效率,结果不能真实反映实际情况。利用灰色系统理论的GM(1,2)模型,结合实例对鱼雷装载失效率和工作失效率的关系进行建模,研究两者之间的关系,推算鱼雷装载失效率。计算结果表明,该方法能达到令人满意的拟合和预测精度,方法简单,具有实用价值。

There is few torpedo stowage information. If evaluate the torpedo stowage failure rate directly using the mathematical statistics method, the result can＇t reflect fact. This paper uses the GM （1,2） model of the grey system theory to set up the torpedo failure rate and the torpedo work failure rate relationship model, studies the relationship between them, then ,forecasts the stowage failure -ate which is lack of experiment data. The result indicates that this model can achieve satisfactory precision. At the same time, it has practical value.
