摘要
就统计过程控制在实施过程中遇到的若干问题进行深入研究,首先进行判异准则的小概率推算,纠正了过去小概率计算中一些错误;其次论述了过程异常的两面性及其对过程的改进作用,最后说明进行SPC不能单纯依赖控制图,还应进行能力分析(即技术稳态分析),并及时有效地采取措施对过程进行改进,才能从实施统计过程控制中获得效益.
The paper deeply researches many problems in the execution of statistics control. Firstly it deduces the abnormality-judging standards for small probability, and corrects some errors in the past computations. Secondly it explains the two sides of process abnormality and its improvement on the process. Finally it explains that SPC-conducting can＇t only depend on control charts but should do capability analysis （that is the steady state of technology）, and timely and effectively take measures on improving the process, which results in obtaining efficiency in the SPC.
