研究过程的工作质量与产品的质量的测定——过程产品不合格品率和过程能力指数的关系,前者是反映生产过程(批)中的工作质量的指标,而不反映产品本身的质量;而后者不仅可以描述过程的工作质量水平而且特别关注产品本身(注意到σ的计算这里的产品并不是指一件产品)的质量;好的(理想的)不合格品率谨是好的过程能力的必要条件;要改进过程产品质量水平就不能只满足于保持基本的合格品率,还应该进一步查找问题,分析波动产生的原因。
研究過程的工作質量與產品的質量的測定——過程產品不閤格品率和過程能力指數的關繫,前者是反映生產過程(批)中的工作質量的指標,而不反映產品本身的質量;而後者不僅可以描述過程的工作質量水平而且特彆關註產品本身(註意到σ的計算這裏的產品併不是指一件產品)的質量;好的(理想的)不閤格品率謹是好的過程能力的必要條件;要改進過程產品質量水平就不能隻滿足于保持基本的閤格品率,還應該進一步查找問題,分析波動產生的原因。

Through the study of process capability index and the process of the nonconforming rate, puts forward it is one of two closely related but different in principle from the concept; they were from different perspective describes the process of quality ability: The former is reflected in the production process quality of work index, and do not reflect the quality of the product itself;The latter can not only describe the work quality level of process and pay special attention to the product itself ( see products and calculate the sigma is not a product of quality );good rate of unqualified products is a good process ability the necessary conditions to improve quality level; it can not only satisfy basically the rate of qualified products, should also find the problem, analyzing fluctuation reasons, eliminate the effect, the inclusion criteria.
