  1. 1. Health Monitoring for Aircraft Systems using Decision Trees and Genetic Evolution

    Author : Mike Gerdes; Diego Galar; Uday Kumar; Dieter Scholz; Piotr Bilski; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Condition Monitoring; Remaining Useful Life Prediction; Decision Tree; Genetic Algorithm; Fuzzy Decision Tree Evaluation; System Monitoring; Aircraft Health Monitoring; Feature Extraction; Feature Selection; Data Driven; Health Prognostic; Knowledge Based System; Supervised Learning; Data-Driven Predictive Health Monitoring; Health Indicators; Machine Learning; Big Data; Pattern Recognition; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : 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. READ MORE

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

    Author : Mike Gerdes; Petter Krus; Diego Galar; Linköpings universitet; []
    Keywords : Condition Monitoring; Condition Prediction; Failure Prediction; Decision Trees; Genetic Algorithm; Fuzzy Decision Tree Evaluation; System Monitoring; Aircraft Health Monitoring;

    Abstract : 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.

  3. 3. Hybrid modelling in condition monitoring

    Author : Urko Leturiondo; Diego Galar; Uday Kumar; Oscar Salgado; Giulio D'Emilia; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : 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. READ MORE

  4. 4. On the Role of Data Quality and Availability in Power System Asset Management

    Author : Wadih Naim; Patrik Hilber; Ebrahim Shayesteh; Diego Galar; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data quality; asset management; power systems; maintenance optimization; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In power system asset management, component data is crucial for decision making. This thesis mainly focuses on two aspects of asset data: data quality and data availability.The quality level of data has a great impact on the optimality of asset management decisions. READ MORE

  5. 5. Integrating Ergonomics in Maintainability Design Process

    Author : Kiumars Teymourian; Diego Galar; Dammika Senevirante; Phillip Tretten; Syberfeldt Anna; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ergonomics; maintainability; safety; risk analysis; low back compression; ALBA; 3 D Static Strength Prediction Program; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Engineered designed systems or products influence the intended humans through their interactions and interface with the systems. A system or product is an object whereas a human is a living complex system, and most of human characteristics, such as capabilities and limitations, are known. READ MORE
