Nonparametric progressive sign chart for monitoring process location based on individual data
TLDR
This article develops the NP progressive mean sign (NPPM-SN) chart for monitoring the process target through 100% inspection by taking individual measurements from the process by using average run length and some other characteristics of the run-length distribution.Abstract:
Statistical process control (SPC) plays a vital role in the maintenances and improvements of quality outputs in manufacturing, industrial and service production processes. Control chart is an impor...read more

A non-parametric exponentially weighted a moving average signed-rank chart for monitoring location
TL;DR: An extensive simulation study is done on the performance of the two-sided NPEWMA-SR chart including a detailed comparison with a number of existing control charts, including the traditional EWMA chart for subgroup averages and some nonparametric charts i.e. runs-rules enhanced Shewhart-type SR charts.

On Designing Mixed Nonparametric Control Chart for Monitoring the Manufacturing Processes
TL;DR: A modified nonparametric exponentially weighted moving average chart under progressive setup based on sign and arcsine test statistics is proposed and performs efficiently in detecting small and persistent shifts in the process location under each choice of the smoothing parameter.

A new two-sided cumulative sum quality control scheme
TL;DR: In this article, a two-sided cumulative sum quality control scheme was proposed and compared to a multivariate cumulative sum scheme with fast initial response features and a Markov chain approximation was used to calculate the average run lengths.
