Abstract
- The memory‐type control charts are quite efficient in monitoring small and moderate shifts in process parameters. These charts, such as exponentially weighted moving average (EWMA), face the problem of inertia due to the time dependence of statistics. This issue could be solved to some extent using a break at regular/irregular intervals in plotting statistics. We have proposed this method by introducing a break feature at regular intervals, to handle the inertia problem, and found it quite useful for memory control charts. A comparative analysis of the proposal with some existing charts is also part of the study. [ABSTRACT FROM AUTHOR]
