TLDR
In this paper, the authors evaluate the performance of the DS X ¯ chart when process parameters are estimated by means of a new proposed theoretical method, and show that performances with estimated parameters are different from that with known parameters, and propose three optimal design procedures.About:

Probability‐type, Shewhart‐type and EWMA control charts for individual observations from the two‐parameter Lindley distribution
TL;DR: In this paper , the authors constructed probability-type, Shewhart-type and EWMA control charts for individual observations from the two-parameter Lindley distribution, investigate and compare their performance and illustrate them using examples with both simulated and real data.

A simplex method for function minimization
John A. Nelder,R. Mead +1 more
TL;DR: A method is described for the minimization of a function of n variables, which depends on the comparison of function values at the (n 41) vertices of a general simplex, followed by the replacement of the vertex with the highest value by another point.

Exponentially weighted moving average control schemes: Properties and enhancements
TL;DR: The recognition that an EWMA control scheme can be represented as a Markov chain allows its properties to be evaluated more easily and completely than has previously been done.

TL;DR: In this article, the authors evaluate the properties of an exponentially weighted moving average (EWMA) control scheme used to monitor the mean of a normally distributed process that may experience shifts away from the target value.

Effects of Parameter Estimation on Control Chart Properties; A Literature Review
TL;DR: In this article, the control chart limits are calculated using parameter estimates from an in-control Phase I reference sample, and statistics based on new samples are compared with the estimated control limits to monitor for departures from the in..
