Lower confidence limits on process capability indices based on the range
暂无分享,去创建一个
The common measures of process capability, usually indicated by Cp, CPU, CPL, and Cpk are considered. Tables of lower confidence limits are given on these measures where the sample mean, and the sample range (properly adjusted by d2) are substituted for the population mean and population standard deviation in the definition formulas.
