摘要
提出了可变抽样区间的带警戒限均值控制图。利用转移概率流图(TPFG)方法得到了发信号前的平均样本数,进而推导出了发信号前的平均时间。
One-side mean control charts with warning limits under variable sampling intervals are proposed.Using the method of transition probability flow graphs(TPFG),the average sampling number to signal for these charts is given,and the average time to signal for these charts is deduced.
