摘要
给出基于双侧等截尾正态分布的均值-极差控制图控制限的表达式,计算出参数估计使用的控制图系数表及样本量和子组容量的取值,最后给出基于正态分布和双侧等截尾正态分布两种情况下平均链长的比较。
Giving the control lines of mean-range control charts based on double equal truncated normal distribution,the control charts coefficient table for evaluating parameters is computed,sample size and subsample size.In the end,the average run lengths are compared according to both hypothesis of normal distribution and double equal truncated normal distribution.
