Graphical Representation of Run Length Distributions

ABSTRACT With the development of techniques to compute run length distributions for various types of control charts, numerous researchers have advocated using these distributions. However, it is unclear how practitioners are expected to use run length distributions in making decisions about control chart performance and chart design. To alleviate this problem, we present a graphical method of representing run length distributions. Our method allows for the easy comparison of several distributions which is not currently permitted with standard types of distribution plotting.
