对于试验者设计一个寿命试验的重要部分是确定为达到一个特定的精密度所必需的子样容量。故障率函数常被用作判决准则,在替换决定的时候尤其如此。在本文中我们说明了为选择这个子样容量,必需以一个特定的精密度估计某点上的故障率函数,我们提供一个易用的程序,它能用在威布尔分布以及达到预定的试验时间以后而终止的寿命试验上。说明了对其它的失效时间分布和其它的寿命试验类型的应用方法。
An important part of designing a lifetime test for the experimenter is to determine the subsample capacity necessary to achieve a particular degree of precision. The failure rate function is often used as a decision criterion, especially when replacing decisions. In this paper we show that in order to select this subsample capacity, it is necessary to estimate the failure rate function at a certain point with a certain precision. We provide an easy-to-use program that can be used in the Weibull distribution and to achieve a predetermined test time After the termination of the life test. Describes how to apply other failure time distributions and other life test types.
