Abstract:
|
A class of Shewhart-type control charts is studied. A key advantage of these distribution-free charts is that the in-control run length distribution is the same for all continuous process distributions. Various properties of the charts are studied via evaluations of the run length distribution and the ARL. It is seen that from a robustness point of view, the proposed charts are preferable to the classical Shewhart charts and, in fact, they have attractive ARL properties over other standard parametric charts in certain situations.
