1. Constructive cooperative coevolution for optimising interacting production stations
Sammanfattning : Engineering problems have characteristics such as a large number of variables, non-linear, computationally expensive, complex and black-box (i.e. unknown internal structure). These characteristics prompt difficulties for existing optimisation techniques. LÄS MER
2. Succinic acid production using metabolically engineered Escherichia coli
Sammanfattning : The prospects of peak oil, climate change and the dependency of fossil carbon have urged research and development of production methods for the manufacture of fuels and chemicals from renewable resources (biomass). To date, the primary emphasis has been placed on the replacement of oil for transportation fuels. LÄS MER
3. A Framework for optimised welding of fatigue loaded structures : Applied to gas metal arc welding of fillet welds
Sammanfattning : Welding is a key process for heavy steel structures, but it is also a weak link in the structure since fatigue fractures in welds are a common cause of failure. This thesis proposes several changes in order to improve the fatigue properties in acost effective way, enabling reduced weight and reduced cost of welded structures. LÄS MER
4. Dynamiskt belastade tribologiska system under plastisk formning, del II --- analyserade genom akustisk emission
Sammanfattning : The dynamic friction process and contact surface between tool and working material in a plastic forming process is hard to describe in mathematical form and hard to monitor and control in real time. High production speed and highly optimised forming operations result in great demands on the control equipment. LÄS MER
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
