Abstract:
      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.
