摘　　要：基于总体分布有偏并假定总体分布未知情况下均值-极差控制图的控制限的研究结果,将其推广到EWMA均值控制图,给出总体分布有偏并假定总体分布未知情况下EWMA均值控制图的控制界限,并以质量特性值服从对数正态分布为例,给出EWMA均值控制图的控制效果的模拟分析.This paper accord to the control lines of mean-range control charts based on the skewed population which is unknown results, spreading it to exponentially weighted moving average chart, give the control lines of exponentially weighted moving average chart based on the skewed population which is unknown., then make a simulation to the effect of exponentially weighted moving average chart based on quality characteristic according to log-normal distribution.

关 键 词：有偏总体 EWMA均值控制图 对数正态分布 平均链长
