165. New CUSUM Charts, the GLR Procedure and the Parabolic Mask

Sven Knoth (Helmut Schmidt University Hamburg, Germany)

Process

The cumulative sum (CUSUM) control chart iterates sequential probability ratio tests (SPRT) until the first SPRT ends with rejecting the null hypothesis. Because the latter exhibits some deficiencies if the true mean is substantially different to the one used in the underlying likelihood ratio, Abbas (2023) proposes to substitute the SPRT by a repeated significance test (RST), cf. to Armitage...

75. Challenges and Obstacles in Process Understanding and Monitoring with Process Analytical Technologies

Dr Giulia Gorla (University of Insubria)

12/09/2023, 18:10

Process

The use of Process Analytical Technology (PAT) in dairy industries can enhance manufacturing processes efficiency and improve final product quality by facilitating monitoring and understanding of these processes. Currently, near-infrared spectroscopy (NIR) is one of the most widely used optical technologies in PAT, thanks to its ability to fingerprint materials and simultaneously analyze...

97. Unravelling Sources of Variation in Large-Scale Food Production with Power Spectral Density Analysis

Dr Lars Erik Solberg (Nofima)

12/09/2023, 18:30

Process

Quality testing in the food industry is usually performed by manual sampling and at/offline laboratory analysis, which is labor intensive, time consuming, and may suffer from sampling bias. For many quality attributes such as fat, water and protein, in-line near-infrared spectroscopy (NIRS) is an alternative to grab sampling and which provides richer information about the process.

In this...
