Campaign-based modeling for degradation evolution in batch processes using a multiway partial least squares approach
Wu, Ouyang; Bouaswaig, Ala; Imsland, Lars Struen; Schneider, Stefan; Roth, Matthias; Moreno Leira, Fernando (Journal article; Peer reviewed, 2019)In the process industry, various types of degradation occur in processing plants, resulting in significant economic losses. Modeling of degradation is important because it provides quantitative insights for consideration ... -
Data-driven degradation model for batch processes: a case study on heat exchanger fouling
Wu, Ouyang; Bouaswaig, Ala; Schneider, Stefan; Leira, Fernando; Imsland, Lars Struen; Roth, Matthias (Journal article; Peer reviewed, 2018) -
Optimal production and maintenance scheduling for a multiproduct batch plant considering degradation
Wu, Ouyang; Dalle, Ave; Harjunkoski, Iiro; Bouaswaig, Ala; Schneider, Stefan; Roth, Matthias; Imsland, Lars Struen (Peer reviewed; Journal article, 2020)Performance decay due to asset degradation is an important constraint in industrial production and therefore needs to be actively considered. This paper focuses on short-term scheduling for multiproduct batch processes ... -
Robust state estimation for fouling evolution in batch processes using the EM algorithm
Wu, Ouyang; Imsland, Lars Struen; Brekke, Edmund Førland; Schneider, Stefan M; Bouaswaig, Ala EF; Roth, Matthias (Journal article; Peer reviewed, 2019)Degradation such as fouling has significant negative impact on the efficiency of process manufacturing. Creating transparency about degradation is essential in the operations of the plants. This paper focuses on the state ... -
Short-term Scheduling of a Multipurpose Batch Plant Considering Degradation Effects
Wu, Ouyang; Dalle Ave, Giancarlo; Harjunkoski, Iiro; Imsland, Lars Struen; Schneider, Stefan M; Bouaswaig, Ala EF; Roth, Matthias (Journal article; Peer reviewed, 2019)Fouling is a typical type of degradation in the process industries, which results in significant negative effects on the efficiency of plants. This paper considers a case study, where production tasks with different recipes ...
