In many reliability applications, there may not be a unique plausible scale in which to measure time to failure or assess performance. This is especially the case when several measures of usage are available on each unit. For example, the age, the total number of flight hours, and the number of landings are usage measures that are often considered important in aircraft reliability. Similarly, in medical or biological applications of survival analysis there are often alternative scales (e.g., Oakes, 1995). This paper considers the definition of a "good" time scale, along with methods of determining a time scale.
在许多可靠性应用中，可能不存在一个唯一合理的尺度来测量失效时间或评估性能。当每个单元有几种使用量度时，情况尤其如此。例如，机龄、飞行总小时数和着陆次数是在飞机可靠性中通常被认为很重要的使用量度。同样，在生存分析的医学或生物学应用中，通常也有替代尺度（例如，奥克斯，1995年）。本文考虑了“良好”时间尺度的定义以及确定时间尺度的方法。
