中文摘要:
      在工序质量控制中,画控制图的传统作法是用样本均值近似代替总体的均值.由于样本的随机性,因此,估计误差在所难免.本文用Bayes方法将用样本均值χ代替总体均值μ所产生的估计误差一并计入到总体X所固有的随机性之中,从而修正了传统的质量控制界限的画法
英文摘要:
      Traditional way of plotting control chart in the process quality control is the use of sample mean instead of population mean. Estimating error is hard to avoid because of the simple′s randomness. In this paper, we use Bayesian method to consider estimating error, which is produced by sample mean X replacing population mean μ , belonging to fixed randomness of population rv X , thus correcting the traditional way of quality control limits.
