将 GARCH模型引入到自相关质量过程控制图中 ,提出了 GARCH型控制图 ,为方差随时间变化的过程提供了处理工具 ,可以解决实际工作中因设备、原材料或操作因素使质量波动水平发生变化的控制问题
The GARCH model is introduced into the autocorrelation quality process control chart, and a GARCH control chart is proposed to provide a processing tool for the process of variance with time, which can solve the problem that the quality fluctuation level changes due to equipment, raw materials or operation factors in the actual work Control problem
