摘　　要：本文根据 Ｃｏｓｔａ的可变样本容量的控制图的模型设计具有可变样本容量的和 Ｒ图．计算了在可变样本容量（ＶＳＳ）下发信号前的平均样本数和平均时间，并同固定样本容量（ＦＳＳ）和可变抽样区间（ＶＳＩ）的和 Ｒ图作比较．This paper proposes median and range charts with variable sample size based on Costa model of control chart , working out the average number of samples to signal and the average time to sighal for and R charts under the variable sample size. In the meantime, the author compares these charts with the fixed sample size and the variable sampling intervals and R charts.
