目前,接近零不合格过程的质量控制已成为质量控制理论中的一个新的发展方向。本文建立了基于正态分布的零不合格品质量控制图,弥补了传统休哈特质量控制图的不足。
At present, the quality control of the near-zero non-conformity process has become a new development direction in the quality control theory. In this paper, a zero-defect quality control chart based on normal distribution is established to make up for the deficiencies of the traditional Shewhart quality control chart.
