Information Systems Journal, Volume 36, Issue 3, Page 315-339, May 2026.ABSTRACT Artificial intelligence (AI) brings great potential for manufacturers, but clashes with the established culture due to the unexplainable and opaque nature of the solutions it provides. Having little experience in AI and machine learning (ML), most manufacturing leaders experience barriers implementing AI.

The Poisson CUSUM Chart for Monitoring Small Counts: Addressing the Estimation Uncertainty
Biometrical Journal, Volume 68, Issue 2, April 2026.ABSTRACT This study addresses the impact of estimating in‐control parameters on the performance of the Poisson cumulative sum (CUSUM) chart in detecting an increase in the mean when the counts are small. To reduce false signals induced by estimation uncertainty, recommendations prescribe impractically large sample sizes or propose methods that widen ...

Comparison of control charts for monitoring clinical performance using binary data. [PDF]
, 2017 BACKGROUND: Time series charts are increasingly used by clinical teams to monitor their performance, but statistical control charts are not widely used, partly due to uncertainty about which chart to use.

Quality and Reliability Engineering International, Volume 42, Issue 3, Page 933-949, April 2026.ABSTRACT Percutaneous transhepatic biliary drainage (PTBD) catheter placement is known to have a high readmission rate. This work focuses on monitoring the change in readmission rate after a new clinical paradigm for post‐procedural care is implemented for the PTBD procedures.

New Shewhart-EWMA and Shewhart-CUSUM Control Charts for Monitoring Process Mean [PDF]
Scientia Iranica, 2018 In this paper, we propose new Shewhart-EWMA (SEWMA) and Shewhart-CUSUM (SCUSUM) control charts using the varied L ranked set sampling (VLRSS) for monitoring the process mean, namely the SEWMA-VLRSS and SCUSUM-VLRSS charts. The run length characteristics of the proposed charts are computed using extensive Monte Carlo simulations. The proposed charts are
