2. 1. Cost Optimization of Aircraft Structures

   Author : Markus Kaufmann; Dan Zenkert; Malin Åkermo; Per Wennhage; Erik Lund; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; Vehicle engineering; Farkostteknik;

   Abstract : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. READ MORE

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automation; electrified propulsion; long combination vehicles; electromobility; propulsion system tailoring; automated driving systems; optimal control; single-track and two-track vehicle models; predictive energy management and vehicle stability; motion control; longer heavier vehicles; vehicle stability; optimal energy management; total cost of ownership; optimization; transportation mission; heterogeneous heavy vehicle fleet; fleet sizing;

   Abstract : This thesis proposes methodologies to improve heavy vehicle design by reducing the total cost of ownership and by increasing energy efficiency and safety. Environmental issues, consumers expectations and the growing demand for freight transport have created a competitive environment in providing better transportation solutions. READ MORE

5. 3. Applying quantum approximate optimization to the heterogeneous vehicle routing problem

   Author : David Fitzek; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combinatorial optimization; variational quantum algorithm; Quantum computing; quantum approximate optimization algorithm; vehicle routing;

   Abstract : Quantum computing offers new heuristics for combinatorial problems. With small- and intermediate-scale quantum devices becoming available, it is possible to implement and test these heuristics on small-size problems. READ MORE

6. 4. Longitudinal Force Distribution and Road Vehicle Handling

   Author : Matthijs Klomp; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ehicle dynamics; quasi steady-state; drive force; combined grip; longitudinal force distribution; combined slip; vehicle handling; optimization;

   Abstract : The distribution of longitudinal forces has a large influence on vehicle handling characteristics such as the driver/vehicle interaction, road holding and yaw stability, in particular during combined traction/braking and cornering near the grip limit of the tires. In order to select and develop suitable driveline systems and associated active control that provide consistent driver/vehicle handling, maximum road holding and sufficient yaw stability margins, it is essential to understand the influence of a particular drive force distribution on these handling characteristics.

7. 5. Transportation Mission Based Optimization of Heavy Vehicle Fleets including Propulsion Tailoring

   Author : Toheed Ghandriz; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; heterogeneous heavy vehicle fleet; optimal energy management; propulsion system tailoring; Automated Driving Systems; electrified propulsion; total cost of ownership; electromobility; transportation mission; fleet sizing;

   Abstract : Over decades freight vehicles were produced for a wide range of operational domains so that vehicle-manufacturers were not concerned much about the actual use-cases of the vehicles. Environmental issues, costumer expectations along with growing demand on freight transport created a competitive environment in providing better transportation solutions. READ MORE
