摘要
在复杂系统的可靠性评估中,将不同分布的寿命数据转换为成败型数据,然后利用成败型数据对整个电子产品进行可靠性评估是一种重要的处理方法.本文给出了数据等效性的相关概念和准则,并在建立的准则下对文献中提及的三个等效数据转换公式的优良性在指数分布定数截尾试验数据情形进行了比较.从比较的结果看,文中所提及的转换公式B在所给出的等效性准则下优于其他两个转换公式A和C。
In complex system reliability evaluation, it is a very important method that the different kinds of distributions test datum are transformed into success/failure data, then using the success/failure data to predict the product＇s reliability characters. In this paper, the definitions and criterions of equivalent data have been proposed. Then, Based on the criterions we have established, three different equivalent formulas in the bibliography have been compared in exponential type Ⅱ censored data. From the analysis, we found that the formula B is much better than the other two formulas A and C mentioned in this paper.
