在对测量过程实施控制时,常常采用控制图来分析和检验测量过程是否受控。控制图又称管理图,是画有控制界限的一种图,是受控过程状态的显示技术,利用它可直观地反映过程的变动性,判断其是否处于稳定状态,并能及时检验出异常变动,从而采取纠正措施。控制图对于测量过程控制的监视非常直观有效,但在测量管理体系运行维护过程中,很少有企业能很好地运用该技术,妨碍其普及应用的主要原因就是其运算繁琐、图形制件麻烦、
In the control of the measurement process, often use the control chart to analyze and test whether the measurement process is controlled. Control chart, also known as management chart, is a kind of chart with control limits. It is a display technology of the controlled process status. It can directly reflect the process variability, judge whether it is in a steady state and detect abnormalities in time Change, so as to take corrective measures. Control charts are very intuitive and effective for the monitoring of process control. However, few enterprises are able to make good use of this technology during the operation and maintenance of measurement management systems. The main reason that hinder their popularization and application is that they are cumbersome in operation and troublesome in graphic parts ,
