在鱼雷可靠性评定中,传统的方法是基于布尔系统理论,较少考虑到“合格”和“不合格”之间的过度状态.为了更客观真实的评价鱼雷可靠性水平,在模糊数学的基本理论基础上,提出了新的合格度计算方法,建立了一种由模糊数表示试验结果的模型,进而提出了用 Bayes 方法对可靠性水平进行评定的方法,得出了一个表示鱼雷可靠性水平的模糊区间.这种方法不仅更符合实际情况,而且具有 Bayes 方法节省试验样本的优点,算例结果表明了该方法的可行性.

Conventional Boolean algebra-based reliability assessment methods for a torpedo consider little transition state between ‘qualified’ and ‘unqualified’. In order to assess the reliability level of a torpedo more objectively and ex-actly, a novel reliability assessment model is put forward on the basis of fuzzy mathematics, in which test results are represented by fuzzy numbers. Then the Bayes method is adopted in assessment of reliability level to obtain a fuzzy zone indicating reliability level of a torpedo. This method is more practical and shows a saving in test samples. Feasibility of the present method is verified by an example.
