1. Satistical Modelling Of CO2 Exchange Between Land And Atmosphere : Using Stochastic Optimisation And Gaussian Markov Random Fields
Sammanfattning : This thesis focuses on the development and application of efficient mathematicaltools for estimating and modelling the exchange of carbon dioxide (CO2) between the Earth and its atmosphere; here referred to as the global CO2 surface flux.There are two main approaches for estimating the CO2 flux: Processed based(bottom-up) modelling and atmospheric inversion (top-down) modelling.

2. Analysis and Optimisation of Real-Time Systems with Stochastic Behaviour
Sammanfattning : Embedded systems have become indispensable in our life: household appliances, cars, airplanes, power plant control systems, medical equipment, telecommunication systems, space technology, they all contain digital computing systems with dedicated functionality. Most of them, if not all, are real-time systems, i.e. LÄS MER
3. Optimisation of Long-Term Industrial Planning
Sammanfattning : In this thesis, long-term optimisation methods for industrial transition processes have beendeveloped, taking monetary and environmental considerations into account. Two different methods forinvestment optimisation have been developed. LÄS MER
4. Life Cycle Energy Optimisation: A multidisciplinary engineering design optimisation framework for sustainable vehicle development
Sammanfattning : This thesis explores how the systemic-level environmental footprint of light-duty vehicles could be reduced through integrative design using the Life Cycle Energy Optimisation (LCEO) methodology. This methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle; while complying with a set of functional constraints, thereby avoiding any sub-optimal energy demand shifts between the vehicle's different life cycle phases.

5. Manufacturing management and decision support using simulation-based multi-objective optimisation
Sammanfattning : A majority of the established automotive manufacturers are under severe competitive pressure and their long term economic sustainability is threatened. In particular the transformation towards more CO2-efficient energy sources is a huge financial burden for an already investment capital intensive industry. LÄS MER
