用Bootstrap法确定稳健设计中最优工况的联合置信区域

Determination of the Joint Confidence Region of Optimal Operating Conditions in Robust Design by Bootstrap Technique

Chanseok Park

摘要:

稳健设计已被广泛认为是减少变异性和提高质量的主要方法。大多数工程统计文献主要集中在寻找稳健设计的最佳操作条件的“点估计”。计算点估计的最佳操作条件的各种程序被认为是。虽然这种点估计程序对于持续的质量改进很重要,但直接的问题是“这些最佳操作条件的准确性如何?“这个问题的答案是考虑单个变量的区间估计或多个变量的联合置信区域。在本文中,与引导技术的帮助下,我们开发的程序获得联合“置信区域“的最佳操作条件。两个不同的程序使用Bonferroni和多元正态近似介绍。所提出的方法进行了说明和证实,使用数值例子。

英文摘要:

Robust design has been widely recognized as a leading method in reducing variability and improving quality. Most of the engineering statistics literature mainly focuses on finding "point estimates" of the optimum operating conditions for robust design. Various procedures for calculating point estimates of the optimum operating conditions are considered. Although this point estimation procedure is important for continuous quality improvement, the immediate question is "how accurate are these optimum operating conditions?" The answer for this is to consider interval estimation for a single variable or joint confidence regions for multiple variables. In this paper, with the help of the bootstrap technique, we develop procedures for obtaining joint "confidence regions" for the optimum operating conditions. Two different procedures using Bonferroni and multivariate normal approximation are introduced. The proposed methods are illustrated and substantiated using a numerical example.
