A number‐between‐events control chart for monitoring finite horizon production processes

In this paper, we present a number-between-events (NBE) control chart for monitoring the fraction nonconforming in finite horizon production (FHP) processes and related specific performance measures. When fractions FHP processes, common binomial p $p$ -chart has two crucial limitations: underlying distributional assumptions are violated when dealing with low-volume scarce efficiency case of characterized by low nonconforming. Thus, an efficient requires selection correct statistical model: case, distribution from hypergeometric family discrete distributions. An can be achieved means time-between-events (TBE) charts, which count number units up to appearance fixed sample. Here, TBE-chart, denoted as NBE-chart, based on negative that meets numerous requirements processes. The proposed conveniently used both mass frequent changeovers.
