Abstract
Process capability indices such as Cp, CpL, CpU, and Cpk have been used for evaluating the performance of a manufacturing process in statistical quality control and statistical process control fields. In this paper, a Bayes estimator of Cpk is constructed such that the prior mean is set to be equal to a specified value while the prior distribution is weakly informative. This estimator is compared with conventional Bayes and non Bayes estimators.

具有指定先验均值的过程能力指数 Cpk 的贝叶斯估计量
摘要
C p、C pL、C pU和C pk等过程能力指数已在统计质量控制和统计过程控制领域用于评估制造过程的性能。在本文中,构建了C pk的贝叶斯估计量,使得先验均值设置为等于指定值,而先验分布信息量较小。该估计量与传统贝叶斯和非贝叶斯估计量进行了比较。
