摘要
Ｍｕｎｆｏｒｄ根据累积得分法设计了平均值的质量控制图，作者（１９８８年）设计了中位值和极差的累积得分控制图，Ｎｃｕｂｅ和Ｗｏｏｄａｌｌ（１９８４年）给出了联合Ｓｈｅｗｈａｒｔ—累积得分的平均值图，本文设计了联合常规—累积得分的中位值和极差图．
This paper proposes the Combined ordinary-cumulative score median and range charts controlling quality by making use of the combined shewhart-cumulative score method of Ncube and Woodall, computing the average run length of the two kinds of charts and comparing these charts with the cumulative score control charts of median and range.
