摘要
介绍了基于对数方差的累积和控制图,进行了可变抽样区间的控制图设计用Markov链方法计算可变抽样区间的累积和方差控制图的平均报警时间,并且与固定抽样区间的控制图进行比较,分析在不同参数取值下的平均报警时间.
In this paper, a cumulative sum control chart based on logarithm variance is present, which is designed with the variable sampling intervals. And then, the Markov chain's method is used to count the average alarm time to signal. After that, we can compare the variable sampling intervals' control charts with the fixed sampling intervals', furthermore, analyze the results when the parameters datum are different.
