The fundamental assumption for Shewhart control Charts is that the statistics desired to control the quality depend on normal distribution.
体哈特控制图的基本假定是欲控质量特性的统计量服从正态分布。
The forewarning control limits and time series regression judgment model are built up based on the reliability series model in a non-repairable system and Shewhart control charts.
研究结果:利用不可修复可靠性串联模型与休哈特控制图建立预警控制界限,建立时间序列回归判别模型。
