Design and Optimization of c-Control Chart Using a Triple Sampling Scheme

M. J. Campuzano, J. J. Muñoz, V. Deibe Blanco

In this work, a c-control chart using a triple sampling scheme (TS-c) is proposed. The chart design, procedure, and a bi-objective optimization model are given to optimize the TS-c-chart. The Average Run Length for in-control and out-of-control (ARL1), and Average Sample Number metrics are calculated. A Comparison among TS-c, Fixed parameters c (FP-c), VSS-c, EWMA-c, and Double Sampling c (DS-c) control charts are carried out in terms of ARL1. The proposed TS-c-chart has lower ARL1 values for detecting small and moderate shifts in the mean number of non-conformities in control compared with FP-c, VSS-c, EWMA-c, and DS-c.
