摘要
测量系统的重复性和再现性变异是测量值波动的一个重要来源,它对于过程监测的效果控制图会造成影响。基于测量系统的重复性和再现性分析,讨论了测量系统能力对监测过程的X控制图性能的影响,结果表明符合要求的测量系统对X控制图的性能影响不是很明显,否则影响较大,并通过一个仿真示例验证了该结果。
The variation of measurement systems is a main source for the difference of data.It makes influence for process control and control chart. Based on the analysis of the repeatability and reproducibility of measurement systems, it analyze the effect of the ability of measurement systems on sensitivity of ^-X -bar control chart, Both theoretical analysis and case study show that the incapable measurement systents have great influence on sensitivity of ^-X -bar control chart, and the capable one, little influence on the sensitivity.
