Economic and Economic-Statistical Designs of Multivariate Coefficient of Variation Chart

open access: yesRevstat Statistical Journal, 2022
From the economic perspective, cost minimization is an important part of Statistical Process Control (SPC). The conventional approach in SPC focuses on monitoring the process mean and variance for possible shifts. In some processes, such as clinical and

Towards federated multivariate statistical process control (FedMSPC)

open access: yesCoRR, 2022
The ongoing transition from a linear (produce-use-dispose) to a circular economy poses significant challenges to current state-of-the-art information and communication technologies. In particular, the derivation of integrated, high-level views on material, process, and product streams from (real-time) data produced along value chains is challenging for
