Two-Stage Short-Run (X, MR) Control Charts

Fuzzy Short-Run Control Charts

Statistical control charts are useful tools in monitoring the state of a manufacturing process. Control charts are used to plot process data and compare it to the limits set for the process. Points plotting outside these limits indicate an out-of-control condition. Standard control charting procedures, however, are limited in that they cannot take into account the case when data is of a fuzzy n...

Delete and Revise Procedures for Two-Stage Short-Run Control Charts

The second stage thoracoplasty.

Many surgeons and patients alike share the belief that the second stage of a paravertebral thoracoplasty, in comparison with the first stage, is a simple procedure. This has not been our observation, especially in so far as the comfort of the patient is concerned. This paper is offered to compare the reactions of the patient after the second stage with those which he experienced after the first...

Model based control charts in stage 1 quality control

In this paper a general method of constructing control charts for preliminary analysis of individual observations is presented, which is based on recursive score residuals. A simulation study shows that certain implementations of these charts are highly effective in detecting assignable causes.
