Quality assurance (QA) is important for ensuring precision in radiation therapy. The
complexity and resource-intensive nature of QA has increased with the continual evolution …

When designing control charts the in‐control parameters are unknown, so the control limits
have to be estimated using a Phase I reference sample. To evaluate the in‐control …

Multivariate statistical process control (MSPC) addresses the concurrent monitoring of
several measurements. Since multivariate normality is rare in practice, nonparametric …

Purpose To assess the effect of sampling variability on the performance of individual charts
(I-charts) for PSQA and provide a robust and reliable method for unknown PSQA processes …

Parameter estimation is an important topic in Statistical Process Monitoring, as inaccurate
estimates may lead to undesirable control chart performance. Updating the control chart …

This paper aims at exploring the applications of advanced Statistical Process Control (SPC)
tool like Cumulative Sum (CUSUM) with V-mask for monitoring of advanced materials of …

This article aims to enhance the effectiveness of Phase I in statistical process monitoring by
integrating the assessment of estimation uncertainty into control charts using the …

As a useful tool in statistical process control (SPC), the exponential control chart is more and
more popular for monitoring high‐quality processes. Considering both known and estimated …

The Phase I stage plays a crucial role in process monitoring schemes, as it is during this
stage that valuable information about the process is obtained. However, many available …
