2. 1. 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.
