Design of attribute EWMA type control charts with reliable run length performance
Autor: Philippe Castagliola, Athanasios C. Rakitzis, Petros Maravelakis, Shu Wu
Publikováno v: Communications in Statistics - Simulation and Computation. :1-17
Attribute control charts assuming a Poisson (c chart) or a binomial distribution (np chart) are usually used when the quality characteristic cannot be measured on a continuous scale. For equivalent...

Autor: Kim Phuc Tran, Giovanni Celano, Philippe Castagliola, Petros Maravelakis
Publikováno v: Distribution-Free Methods for Statistical Process Monitoring and Control
Distribution-Free Methods for Statistical Process Monitoring and Control, Springer International Publishing, pp.107-136, 2020, ⟨10.1007/978-3-030-25081-2_3⟩
Distribution-Free Methods for Statistical Process Monitoring and Control ISBN: 9783030250805
The Shewhart Sign (\(\text {SN}\)) control chart is a well-known distribution-free statistical process monitoring tool due to its robustness to the violation of the normality assumption for observations. To the best of our knowledge, there is not yet

On the effect of the measurement error on Shewhart t and EWMA t control charts
Autor: Philippe Castagliola, Petros Maravelakis, Giovanni Celano, Kim Phuc Tran, Huu Du Nguyen
Publikováno v: International Journal of Advanced Manufacturing Technology
International Journal of Advanced Manufacturing Technology, Springer Verlag, 2020, 107 (9-10), pp.4317-4332. ⟨10.1007/s00170-020-05222-z⟩
In the industrial practice, control charts are frequently implemented assuming that the quality characteristic of interest can be accurately measured without errors. In general, this assumption is not realistic: measurement error always exists in qua
