But,the drawbacks of Shewhart's control chart is that when the control chart shows abnormal,it cannot tell us what and where is the assignable cause,i.e.it cannot diagnose the abnormalityof the process.In 1982,Prof.Gongxu Zhang proposed the diagnosis theory with two kinds ofquality,solved the diagnosis problem of assignable cause,thus opened a new direction ofstatistical diagnosis theory and developed the theory of SPC into a new stage ofSPCD(Statistical Process Control and Diagnosis).The multi-operation and multi-index system exists everywhere,in general,nearly all theproduction lines of factories belong to this system.
但休哈特控制图的缺点是,当控制图显示异常时,它不能告知是何原因、何处发生了异常,即不能诊断。1982年,我国著名质量管理专家张公绪教授提出两种质量诊断理论,解决了对异常因素的诊断问题,开辟了统计诊断理论的新方向,将质量控制推向了一个新的发展阶段——统计过程控制与诊断阶段。

Following on the GATF Color reproduction test chart to make some brief account, according to the patrterns function is divided into six major areas: simple color wheel graph is used to distinguish between colors and restore color detection; contact copy control standards section, you can use to test the print process changes in dot; dot number comparison chart, used to select and screen resolutions and paper and putting it in a match for reference, but also reflects the various color version modulational cards and membership cards making parameter is set to reproduce the effect and measurement; whether it is a normal RGB: neutral gray balance control chart; gray balance, this work out Y, m, C; proofing control bars.
下面对GATF彩色复制测试图作一些简单的介绍,按图谱功能分为六大区域:简易色轮图用于辨别颜色和检测色彩还原情况;接触拷贝控制标准段,可以用来检测晒版过程中网点的变化情况;网点线数比较图,用于选择网屏线数和纸张适性的匹配参考,也可反映各色版调制卡和会员卡制作参数的设置作用和测量子再现情况是否正常;三原色中性灰平衡控制图;灰平衡卡,依此算出Y、M、C的比例;打样控制条。

Methods In the conventional internal quality control in the control specimens after the test day, a specimen which total protein result was 60-80 gL^(-1), and albumin result was 30-50 gL^(-1) was selected from the first ten specimens every day, the specimen's TP and ALB results were retested after 3 hours. The difference between the two test results and the difference of the standard deviation were calculated every day for 40 days. Extreme difference quality control chart was established by control limits of range which was calculated by the standard deviation.
在常规室内质控在控后开始检测标本,每天从前10份标本中选出1份总蛋白60~80 gL^(-1)、白蛋白30~50 gL^(-1)的标本,3 h后再重测1次该标本的TP、ALB,每天计算2次测定结果的差值和差值的标准差,连续40个工作日,利用标准差计算双份测定极差的控制限,建立极差型质控图。

The control chart based on the geometric distribution(g-type chart )has been shown to be competitive with p or np chart for monitoring the proportion,especially for applications in high quality manufacturing environments.
在质量控制过程中,对于检测不合格率p的变化,特别是p较小时,基于几何分布的控制图( g-type chart)比基于二项分布的控制图(p-chart或np-chart)能更有效地检测并报警。

In fact, situation with a zero LCL is not uncommon. In this article we propose the g-type chart with asymmetric control limits. It is found that with the nonzero LCL, the power to detect rate increase hasmuch improved and the power to detect rate is nearly fixed, and the in-control average run length is the almost the same as the symmetric control chart.
为了解决检测p增加的问题,我们提出了非对称几何控制图的思想,它解决了虚报率增加和检测p增加之间的矛盾,在保持虚报率与对称几何控制图几乎相等的前提下,大大提高了几何控制图在检测不合格品率增加时的灵敏性和有效性,本文中给出了在不同的?

The control chart based on the geometric distribution(g-type chart) has shown to be competitive with p or np chart for monitoring the proportion especially for application in high quality manufacturing environments. However when the cases with LCL=0 occur, plotting values beneath the LCL is impossible given the non-negative nature of units, such type of lower control limits no ability to detect rate increase.
但是由于几何控制图的自然下限的问题,在其使用过程中若控制下限LCL<0,则取其自然下限为0,这使得几何控制图在此情况下对于检测不合格品率p的增加是几乎不起任何作用,而此问题也是实际中我们最需要检测并作判断的问题。
