A literature review on joint control schemes in statistical process monitoring

Abstract

Process monitoring is regarded as a continuous phenomenon requiring careful consideration to acquire an enhanced output quality. Dispersion and location are significant parameters in the entire process, and timely detection of the changes that occur in a stable process is needed. Today, quality practitioners recommend using a single charting setup offering better capability of detecting joint changes in the parameters of a process. As provided in the literature, a detailed review paper for simultaneous monitoring is conducted in 2013 which many reaserchers were attracted to publish papers in this field. In this paper, a meticulous content analysis (on the basis of 59 reviewed papers in the field of joint monitoring from 2013 to 2021) is exploited to classify the papers that includes joint control charts for statistical process monitoring (SPM), to identify the potential topics and present some suggestions for further studies in simultaneous monitoring.

Novel nonparametric control charts for monitoring dispersion of count data

“…26,27 There are also nonparametric control charts that can jointly monitor process mean and dispersion, such as the ones based on the Lepage statistic [28][29][30][31][32] and the Cucconi statistic, [33][34][35] among others. A recent literature review on joint monitoring schemes can be found in Jalilibal et al 36 Note that most nonparametric control charts mentioned above for monitoring data dispersion are based on the ordering or ranking information of process observations. To some extent, data ordering/ranking would result in a loss of information contained in the original observed data, and it is difficult to control the degree of information loss.…”
