6. Development of a Generic Model for Life Cycle Inventory and Environmental Assessment of Upstream Processes for Electronic Products
Sammanfattning : The goal with the present thesis is to develop tools, methods and models to assess the upstream processes in the life cycle assessment (LCA) methodology for current and new electronic products. The goal is to get a better understanding on how to collect data to be used in a life cycle inventory (LCI) and use life cycle approaches to environmentally assess the electronics. LÄS MER
7. Systemförvaltningsmodeller
Sammanfattning : The term Software Maintenance was coined in the early 1970s. The subject has significance from several points of view. The costs associated with software maintenance are as a rule considerably higher than what the system cost to develop, which is borne out by many studies conducted in different countries over a period of twenty years.

8. Advancing the life cycle energy optimisation methodology
Sammanfattning : The Life Cycle Energy Optimisation (LCEO) 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. This effectively balances trade-offs, and therewith avoids sub-optimal shifting between the energy demand for the cradle-to-production of materials, operation of the vehicle, and end-of-life phases.

9. Information modelling for the manufacturing system life cycle
Sammanfattning : This thesis deals with information modelling within the scope of the manufacturing system life cycle, i.e. the development phase and the operation phase. LÄS MER
10. Road Design for Future Maintenance : Life-cycle Cost Analyses for Road Barriers
Sammanfattning : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. LÄS MER
