实验设计是一系列测试，其中对系统或过程的输入变量进行有目的的改变，并测量对响应变量的影响。实验设计适用于物理过程和计算机模拟模型。实验设计是一种有效的工具，可以最大限度地提高从研究中获得的信息量，同时最大限度地减少收集的数据量。析因实验设计通过同时改变它们而不是一次只改变一个因素来研究许多不同因素的影响。析因设计允许估计对每个因子的敏感性以及对两个或多个因子的组合效应的敏感性。试验设计方法已成功地应用于几个弹道导弹防御系统的敏感性研究，以最大限度地利用最少的计算机模拟运行的信息量。在竞争激烈的测试和评估世界中，需要一种有效的方法来测试许多因素。
Design of experiments is a series of tests in which purposeful changes are made to the input variables of a system or process and the effects on response variables are measured. Design of experiments is applicable to both physical processes and computer simulation models. Experimental design is an effective tool for maximizing the amount of information gained from a study while minimizing the amount of data to be collected. Factorial experimental designs investigate the effects of many different factors by varying them simultaneously instead of changing only one factor at a time. Factorial designs allow estimation of the sensitivity to each factor and also to the combined effect of two or more factors. Experimental design methods have been successfully applied to several Ballistic Missile Defense sensitivity studies to maximize the amount of information with a minimum number of computer simulation runs. In a highly competitive world of testing and evaluation, an efficient method for testing many factors is needed.
