这是两部分文章的第一部分，介绍了计算机模型敏感性分析的统计方法。第一部分界定了敏感性分析的目标，并提出了一个计算机模型，用于说明的目的，在文件中。作为输入到模型中的变量的样本值的选择的必要考虑的讨论。当计算机输出随时间变化时，以及当所有输入变量同时变化时，给出了重要变量的识别细节。对于后一个主题，解释了考虑数据转换的重要性。
This is the first part of a two-part article presenting a statistical approach to the sensitivity analysis of computer models. Part I defines the objectives of sensitivity analysis and presents a computer model that is used for purposes of illustration in the paper. A discussion of the necessary considerations for selection of sample values of variables used as input to the model is given. Details are given for the identification of important variables when the computer output varies with time and when all input variables have been varied simultaneously. For this latter topic the importance of considering data transformation is explained.
