Integration of maintenance scheduling and planning for large-scale asset fleets
Schulze Spüntrup, Frederik; Ave, Giancarlo Dalle; Imsland, Lars Struen; Harjunkoski, Iiro (Journal article; Peer reviewed, 2021)Large fleets of engineering assets that are subject to ongoing degradation are posing the challenge of how and when to perform maintenance. For a given case study, this paper proposes a formulation for combined scheduling ... -
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 ... -
A rolling horizon approach for scheduling of multiproduct batch production and maintenance using generalized disjunctive programming models
Wu, Ouyang; Dalle Ave, Giancarlo; Harjunkoski, Iiro; Imsland, Lars Struen (Peer reviewed; Journal article, 2021)This paper considers joint production and maintenance scheduling of a multiproduct batch chemical manufacturing plant. A Generalized Disjunctive Programming-based formulation is proposed for the scheduling problem, integrating ... -
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 ...
