休哈特控制图是一种数理统计分析工具,它作为一种质量管理工具,不仅适用于工业企业的生产过程,对邮政通信企业的生产过程也是适用的。因为当初休哈特创制控制图时,是利用了正常生产情况下质量特性的分布状态——正态分布曲线的特征及其在概率论上的重要结论。这种科学的原理具有普遍适用性。
The Shewhart Control Chart is a mathematical statistical analysis tool. As a quality management tool, the Shewhart Control Chart is applicable not only to the production process of industrial enterprises but also to the production process of postal communication enterprises. Because when Shewitt originally created the control chart, it took advantage of the distribution of the quality characteristics under normal production conditions - the characteristics of the normal distribution curve and its important conclusion in probability theory. This scientific principle has universal applicability.
