영문 초록

  In the previous studies, we only used population variance to extract process capability index. Even though process is in control, variance by sample is not the population variance of constant but the sample variance of statistic. In contrast with population variance, sample variance has distribution. The process capability index using sample variance is also statistic. In this study, we investigated the distribution characteristic for the process capability index in respect of estimation with error. Also we spread out for applying up to system process capability index component of an individual process capability index.
