Nonparametric precedence chart with repetitive sampling

In most real-world applications, such as production and manufacturing processes, the underlying process distribution does not always follow a normal distribution. cases, statistical control literature recommends use of nonparametric (or distribution-free) charts. This paper introduces new distribution-free precedence chart using repetitive sampling. The performance proposed is investigated in terms average run-length ( ARL ) profile. expressions in-control probability are introduced integral formulas. out-of-control compared to that existing charts with without runs-rules. A numerical example provided real-life data demonstrate application implementation chart.
