Abstract

The uncertainty/indeterminate in control chart parameter/observations affects the performance of the control chart. This paper addresses the indeterminacy and its effect on the Shewhart X-bar control using multiple dependent state repetitive sampling. The probabilities and neutrosophic average run length for in-control and out-of-control processes are derived. The tables and figures of the proposed chart are presented when uncertainty/indeterminate is present in sample size and proceeding subgroups. The efficiency of the proposed chart is compared with the existing charts and the proposed chart is found to be efficient in terms of neutrosophic average run length.
