摘要
研究了一类自相关泊松计数过程的质量监控问题.在对泊松一阶整值滑动平均(INMA(1))过程进行分析的基础上,用条件控制图和残差控制图对这类过程进行监控,并给出了确定控制限的方法及其实施步骤.通过仿真,首先分析了控制限参数变化对受控平均运行链长的影响;然后以平均运行链长为准则,比较了控制图的监控效果.仿真结果表明,两种控制图均能对泊松INMA(1)过程均值发生的较大幅度漂移进行有效监控.
The quality monitoring problem for a type of auto-correlated Poisson counts process is considered.Based on the analysis of Poisson first-order integer-valued moving average(INMA(1)) process,a conditional control chart and a residual control chart are built to monitor this counts process.The method for determining the control limits of the two control charts and its implementing procedure are presented.By simulations,the influence of control limit parameter variation on in-control average run length is analy...
