A mixed control chart to monitor the process

open access: yesInternational Journal of Production Research, 2015
In this paper, we propose a mixed control chart to monitor the process quality using attribute data combined with variable data. The proposed control chart proceeds like an np control chart based on the number of nonconforming parts but requires variable data only when the decision is indeterminate.

A mixed control chart using process capability index

open access: yesSequential Analysis, 2017
ABSTRACTControl charts are considered as a compulsory tool for the monitoring and improvement of the quality of products. The commonly used attribute and the variable control charts are unsatisfactory for process monitoring. To overcome this difficulty, we proposed a monitoring scheme that is an improved technique based on the joint merits of the ...

A mixed nonparametric control chart for efficient process monitoring

International Journal of Advanced Manufacturing Technology, 2018
In this paper, we propose a nonparametric mixed control chart using exponentially weighted moving average and cumulative sum (statistics for efficient monitoring of quality characteristic). The proposed control chart, namely NPMEC chart, proceeds in two steps.

Mixed Tukey EWMA-CUSUM control chart and its applications

Quality Technology and Quantitative Management, 2017
AbstractTukey control chart (TCC) is a popular choice for robust monitoring of process parameters. With the advancement in technology, we develop refined techniques that incorporate multiple aspects in a single structure. This article is a similar effort to design an improved charting structure in the form of mixed Tukey EWMA-CUSUM chart (namely MEC ...

A Mixed Cumulative Sum-Tukey’s Control Chart for Detecting Process Dispersion

open access: yesThe Journal of King Mongkut's University of Technology North Bangkok, 2019
The objective of this research is to propose a mixed Cumulative Sum-Tukey Control Chart (CUSUMTCC) for detecting process dispersion using the range, when the process is symmetric and asymmetric distributions.The performance of CUSUM-TCC is compared with Tukey’s Control Chart (TCC), Cumulative Sum Control Chart (CUSUM) and Exponentially Weighted Moving ...
