    Master-uppsats, Jönköping University/JTH, Avdelningen för datavetenskap

    Författare :Shuzhou Liu; Mpova Mulahuko; [2023]
    Nyckelord :Machine Learning; Deep Learning; Uncertainty estimation; Conformal prediction; Predictive maintenance; RUL; Probabilistic predictions; Decision Tree; Random Forest; Support Vector Regression; Gradient Boosting; LSTM;

    Sammanfattning : This thesis is a cooperation with Knowit, Östrand \& Hansen, and Orkla. It aimed to explore the application of Machine Learning and Deep Learning models with Conformal Prediction for a predictive maintenance situation at Orkla. Predictive maintenance is essential in numerous industrial manufacturing scenarios. LÄS MER

  3. 7. Prognostics for Condition Based Maintenance of Electrical Control Units Using On-Board Sensors and Machine Learning

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Gabriel Fredriksson; [2022]
    Nyckelord :machine learning; random forest; random survival forest; condition based maintenance; cbm; reliability; solder joint failure; thermomechanical cycling; ECU; lifetime prediction; data-driven; statistics; BGA; PCBA; field quality; maintenance; truck; bus; vehicle;

    Sammanfattning : In this thesis it has been studied how operational and workshop data can be used to improve the handling of field quality (FQ) issues for electronic units. This was done by analysing how failure rates can be predicted, how failure mechanisms can be detected and how data-based lifetime models could be developed. LÄS MER

  4. 8. Predictive Maintenance as a Tool for Servitization : The case of a value-added reseller in the construction equipment industry

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Max Kihlborg; Adam Lilja; [2022]
    Nyckelord :Servitization; Productivity-as-a-Service; Predictive maintenance; Industrial maintenance; Machine learning; Value-added reseller; Construction equipment industry; Tjänstefiering; Prediktivt underhåll; Industriellt underhåll; Maskininlärning; Värdeskapande återförsäljare; Anläggningmaskinsbranschen;

    Sammanfattning : The construction equipment industry has been slow to increase its level of servitization, compared to other related sectors such as the car and flight industries. The fundamental problem is the endless variants of machines and business settings that their customers operate in. LÄS MER

  7. 10. An Investigation of Methods for Flow Measurements in a Gasketed Plate Heat Exchanger for Predictive Maintenance

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Viktor Ekström; [2022]
    Nyckelord :gasketed plate heat exchanger; electrical measurements; sensors; predictive maintenance; machine learning; Technology and Engineering;

    Sammanfattning : For a company to stay relevant in the long term, it is essential to keep up with the latest technology and continuously consider new innovative solutions for improving products and services. The gasketed plate heat exchanger (GPHE) is a mechanical device, and this work attempts to investigate different possibilities for incorporating sensor devices and predictive maintenance systems to improve the device.
