Competitive activities always support improvement in quality. In this study, a repetitive group sampling plan is designed to compare the two process yield indices of respective suppliers. A ratio statistic of two yield indices is proposed for estimated linear profiles under normal assumptions. The operating characteristic function is derived by using the distribution of the ratio statistic. Designed parameters are optimized to minimize the sample size required.

In this paper, we present two new dependent mixed sampling plans and a mixed repetitive sampling plan based on the process yield index for linear profiles. A mixed sampling plan includes two stages; the first stage is a combined test by variables and by attributes, and the second stage is tested by attributes only. The first plan is based on the traditional mixed sampling scheme without marginal quality, and the second plan is based on the modified mixed sampling scheme with marginal quality. If a lot is very bad, the probability it can be rejected with the small initial sample is higher for dependent mixed sampling with marginal quality. We compare dependent mixed plans with other types of double sampling plans; the former outperforms the others with respect to average sample number. Additionally, the number of profiles required in the first stage is much smaller than in the second stage. When the inspection is costly and destructive, a mixed repetitive sampling plan includes one stage that combines the inspection by attributes and by variables and allows resampling in some conditions. We compare the mixed repetitive sampling plan with the repetitive sampling plans by attributes and by variables. The probability of acceptance using the mixed repetitive sampling plan performs better than the repetitive sampling plans by attributes and by variables. Three examples are used to illustrate the proposed methods. Copyright © 2017 John Wiley & Sons, Ltd.

“…Ahmad et al (2014) proposed X-bar control chart based on process capability index using repetitive sampling. More detail can be seen in (Ahmad et al 2014;Aslam et al 2012;Aslam et al 2013a;Aslam et al 2013b;Aslam et al 2013c;Aslam et al 2014a;Aslam et al 2014b;Balamurali and Jun, 2006;Balamurali et al 2005;Liu and Wu, 2013;Sherman, 1965, Teh et al 2011Zhang et al 2011) So far, few attempts have been made to introduce repetitive sampling schemes in the area of quality control. Therefore, the main objective of this paper is to develop a control chart for quick detection of the out-of-control process based on PCI C pk under the repetitive sampling scheme, which will be called a repetitive C pk control chart.…”

Control charts are widely used to monitor manufacturing processes for a deterioration in stability. We propose repetitive group sampling control charts based on the process capability index C pk for monitoring process average when the quality characteristic follows a normal distribution. The performance of the repetitive C pk control chart is reported and compared with the existing control chart in terms of the average run length. It is found that the proposed control chart is effective for quickly detecting small shifts in the process mean.
