  2. 1. On maintenance optimization for offshore wind farms

    Author : Francois Besnard; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle cost; optimization; maintenance; maintenance planning; Offshore wind energy; maintenance strategy; maintenance support organization; reliability;

    Abstract : The maintenance cost is known to be an important part of the levelized cost of energy generated by wind parks. Operational costs can be significantly reduced by optimizing decisions for maintenance strategies, maintenance support organization and maintenance planning. READ MORE

  4. 2. Towards strategic development of maintenance and its effects on production performance : A hybrid simulation-based optimization framework

    Author : Gary Linnéusson; Amos H. C. Ng; Tehseen Aslam; Daniel Tesfamariam Semere; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic development; maintenance behavior; maintenance management; sustainable change; tradeoff optimization; system dynamics; discrete event simulation; problem structuring; multi-objective optimization; decision support; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Abstract : Managing maintenance in manufacturing within an economical short-termism framework and taking the consequential long-term cost effects into account is hard. The increasing complexity of managing maintenance and its impact on the business results calls for more advanced methods to support long-term development through effective activities in the production system environment.

  5. 3. Load and Risk Based Maintenance Management of Wind Turbines

    Author : Pramod Bangalore; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; wind energy.; supervisory control and data acquisition SCADA ; condition monitoring system CMS ; Artificial neural networks ANN ; maintenance strategy; maintenance planning; maintenance management; life cycle cost;

    Abstract : The cost of maintenance is a considerable part of the total life cycle cost in wind turbines, especially for offshore applications. Research has shown that some critical components account for most of the downtime in the wind turbines. READ MORE

  6. 4. Maintenance optimization for power distribution systems

    Author : Patrik Hilber; Lina Bertling; Roland Eriksson; Lalit Goel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability Importance Index; Multiobjective Optimization; Maintenance Optimization; Asset Management; Customer Interruption Cost; Reliability Centred Maintenance RCM ; Reliability Centered Asset Management RCAM ; Monte Carlo Simulation; Evolutionary Particle Swarm Optimization.; Electric power engineering; Elkraftteknik;

    Abstract : Maximum asset performance is one of the major goals for electric power distribution system operators (DSOs). To reach this goal minimal life cycle cost and maintenance optimization become crucial while meeting demands from customers and regulators. READ MORE

  7. 5. Cost optimization of maintenance scheduling for wind turbines with aging components

    Author : Quanjiang Yu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integer linear optimization; Age-based preventive maintenance scheduling; Renewal-reward theorem; Weibull distribution; Combinatorial optimization; Wind turbine maintenance; Virtual replacement; Condition monitoring data; Cox proportional hazards method; Linear programming;

    Abstract : A major part of the wind turbine operation cost is resulted from the maintenance of its components. This thesis deals with the theory, algorithms, and applications concerning minimization of the maintenance cost of wind power turbines, using mathematical modelling to find the optimal schedules of preventive maintenance activities for multi-component systems.
