摘要
针对平稳自相关过程,提出了一种过程能力分析方法。该方法利用统计过程控制(statistical processcontrol,SPC)与工程过程控制(engineering process control,EPC)的整合来消除数据的自相关性并判断过程稳态,应用回归和方差分析估计过程均值和方差。给出了该方法的具体步骤,通过一个实例验证了该方法的有效性。
A method of process capability analysis for stable autocorrelation is proposed. By integrating statistical process control (SPC) and engineering process control (EPC), the method removes the correlation of process data and judges if the process is under control. Moreover it estimates the mean and standard deviation by variance analysis and regression method. Finally, the implementing procedure for process capability analysis is proposed, and an example is given to indicate the effectiveness of the proposed method.
