A Robust Control Chart for Monitoring Dispersion

Journal of Applied Mathematics, 2013, vol. 2013, issue 1

Abstract: Most robust control charts in the literature are for monitoring process location parameters, such as mean or median, rather than process dispersion parameters. This paper develops a new robust control chart by integrating a two‐sample nonparametric test into the effective change‐point model. Our proposed chart is easy in computation, convenient to use, and very powerful in detecting process dispersion shifts.
