  1. 1. Predictive Health Monitoring for Aircraft Systems using Decision Trees

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Mike Gerdes; Petter Krus; Diego Galar; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Condition Monitoring; Condition Prediction; Failure Prediction; Decision Trees; Genetic Algorithm; Fuzzy Decision Tree Evaluation; System Monitoring; Aircraft Health Monitoring;

    Sammanfattning : Unscheduled aircraft maintenance causes a lot problems and costs for aircraft operators. This is due to the fact that aircraft cause significant costs if flights have to be delayed or canceled and because spares are not always available at any place and sometimes have to be shipped across the world.

    Sammanfattning : Reducing unscheduled maintenance is important for aircraft operators. There are significant costs if flights must be delayed or cancelled, for example, if spares are not available and have to be shipped across the world. LÄS MER

  3. 3. Hybrid modelling in condition monitoring

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Urko Leturiondo; Diego Galar; Uday Kumar; Oscar Salgado; Giulio D'Emilia; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Assuring the reliability, availability, maintainability and safety of assets is key to business success. A logical first step is to consider the requirements of assets in the design process. However, these concepts must also be assured during the assets’ operation. Consequently, it is important to have knowledge of their actual condition. LÄS MER
