• Optimal Maintenance for Degrading Assets in the Context of Asset Fleets-A Case Study 

      Spuntrup, F Schulze; Dalle Ave, G; Imsland, Lars Struen; Harjunkoski, Iiro (Peer reviewed; Journal article, 2020)
      Decision-making for maintenance of engineering assets is a common challenge in the process industry due to ongoing degradation. With an increasing company-size, this problem becomes more complex from an operational and ...
    • Optimal Maintenance Scheduling for Washing of Compressors to Increase Operational Efficiency 

      Schulze, Frederik Spuentrup; Dalle Ave, G; Imsland, Lars Struen; Harjunkoski, Iiro (Peer reviewed; Journal article, 2019)
      The need for simultaneously decreasing carbon emissions and increasing operational profit motivates gas turbine and gas compressor operators to understand, minimize and control performance deterioration. Fouling is one of ...
    • 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 ...
    • 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 ...
