Guest Editorial: Eighty Years of Control Charts

摘要

Juran (1997) described in his memories the beginning of statistical process control. We can find the remarkable sentence "Shewhart invented the control chart on May 16, 1924." Eighty years passed, and in the meantime control charts have become one of the main important tools in statistics. The idea behind the special issues of Sequential Analysis is two-sided. On the one side, we want to honor the pioneering work of Walter Shewhart. On the other side, several important new developments in this area are described from both the theoretical and practical point of view.
