1. Cost optimization of maintenance scheduling for wind turbines with aging components
Sammanfattning : 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.

2. On Models and Methods for Global Optimization of Structural Topology
Sammanfattning : This thesis consists of an introduction and sevenindependent, but closely related, papers which all deal withproblems in structural optimization. In particular, we considermodels and methods for global optimization of problems intopology design of discrete and continuum structures. LÄS MER
3. Mixed-Integer Optimization Modeling for the Simultaneous Scheduling of Component Replacement and Repair
Sammanfattning : Maintenance is a critical aspect of many industries, playing an indispensable role in ensuring the optimal functionality, reliability, and longevity of various assets, equipment, and infrastructure. For a system to remain operational, maintenance of its components is required, and for the industry to optimize its operations, establishment of good maintenance policies and practices is vital.
