Replication of an experiment is generally considered a necessity in order to distinguish between the real effects of the factors being studied and the random variations that are typically present in the measurements. In many settings, however, experimentation is very expensive and there are many factors that need to be studied. Therefore, experiments may be performed on many combinations of factors without any replication. Unreplicated experiments are often used in studying manufacturing processes, for example, that have many different possible inputs whose levels can be varied. The goal of such processes is to manufacture items with specific properties and as little variability as possible.

为了区分所研究因素的真实影响和通常存在于测量中的随机变化，通常认为有必要进行实验的重复。然而，在许多情况下，实验是非常昂贵的，有许多因素需要研究。因此，可以对多种因素的组合进行实验，但没有任何复制。例如，不可重复的实验经常用于研究有许多不同可能的输入，其水平可以变化的制造过程。这种工艺的目标是制造具有特定属性和尽可能少的可变性的物品。
