1. Optimization of Maintenance Planning for Multi-Component Systems, and Primal-Dual Convergence Characterizations in Convex Optimization
Sammanfattning : This thesis considers two topics within mathematical programming. The first topic is an investigation into the behaviour of primal-dual subgradient algorithms with primal ergodic averaging in the case where it is not known a priori whether the primal program is consistent or not. LÄS MER
2. Contributions to dual subgradient optimization and maintenance scheduling
Sammanfattning : This thesis analyses two topics within the area of mathematical optimization; dual subgradient methods and maintenance optimization. The first two papers consider dual subgradient methods, and the third paper considers maintenance optimization. LÄS MER
3. Topics in convex and mixed binary linear optimization
Sammanfattning : This thesis concerns theory, algorithms, and applications for two problem classes within the realm of mathematical optimization; convex optimization and mixed binary linear optimization. To the thesis is appended five papers containing its main contributions. LÄS MER
4. Energy system operation by Lagrangian relaxation
Sammanfattning : Due to its relatively high total energy efficiency, the application of cogeneration, i.e. simultaneous exploitation of power and heat from the energy transformation process, is receiving increased attention. In many countries cogeneration is today an essential element in the energy supply system. LÄS MER
5. Optimization of low-cost integration of wind and solar power in multi-node electricity systems: Mathematical modelling and dual solution approaches
Sammanfattning : The global production of electricity contributes significantly to the release of CO2 emissions. Therefore, a transformation of the electricity system is of vital importance in order to restrict global warming. LÄS MER
