Abstract: Modeling and monitoring real data from several industrial processes can be a very difficult task. However, if we are able to get a good data fit, the implementation of a parametric control chart for process monitoring is in general better than using a nonparametric procedure in terms of efficiency. We develop control charts for monitoring the parameters of a logistic distribution and its performance is analyzed. A practical application concerning the monitoring of the diameters and lengths of stopper-corks taken from the daily production is also provided to illustrate the adequacy of the logistic distribution to model such type of data and the performance of the previous developed control charts.
