Assuming all samples coming from populations with the same standard deviation σ, the accuracy of estimating σ from observations of different parts influences control limits of target control chart. The dissertation points out shortcoming of traditional standard deviation estimates and proposes a unbiased estimate of σ which results in that the variation of the estimate is minimums and the control limits is set more reliably.

假设不同工件的样本标准方差均来自于同一分布，则以不同工件的样本标准方差对母体标准方差的估计的精确性直接影响了目标控制图控制界限计算的可靠性，本文分析了目标控制图传统的两种母体方差估计方法的合理性或稳健性较差的特点，给出了一种对σ无偏估计的优良方法，从而使这一方差估计量〓的散差最小，则依此最小方差的无偏估计量所得到的控制界限更为精确，更为可靠。
