必应词典为您提供np-chart的释义,网络释义: 不良数管制图;不良产品数量;不良品数控制图;
这次来说明NP(固定样本量的不合格品数??)(即P-chart)如何使用EXCEL2013来制作的。 1.数据准备。 2.绘制UCL、CL、LCL。 框选"C37:AB39"--"插入"--"插入折线图"--"带数据标记的折线图"--调整图表位置大小。 3.添加总不良数。 右键图表--"选择数据"--"添加"--"编辑数据系列"--确定"系列名称"、"系...

QI Macros also has an np chart templateJust drop your data into the yellow shaded cells and the chart is drawn to the right. When you have enough data points, run stability analysis using the chart tools menu.I looked at a number of alternatives (some much more expensive than QI Macros,...
What is the difference between p- and np-charts?p-charts are used with a varying sample sizenp-charts are used with a constant sample size Which chart would you like to use?If unsure, is the sample size constant?This program was developed by Lydia Yu and Lou DeSanzo...

Having all this in mind, this paper explores the notions of uniformly most powerful unbiased tests with randomization probabilities to eliminate the bias of the ARL function of the np-chart and to bring its in-control ARL exactly to ��-1.Morais...

P生成 p 图,NP生成 np 图。 这两个图表都是属性的控制图表。 即,这些图表使用可计数的数据,例如不符合项数和缺陷百分比。 P 图表在控制图表上绘制分数不一致。 分数不一致是子组中不一致或有缺陷的项占该子组中的项总数的比例。 此度量以十进制表示,有时以百分比表示。 控制图的中心线是子组分数的平均值...
