1. 1. Customizable Contraction Hierarchies for Mixed Fleet Vehicle Routing : Fast weight customization when not adhering to triangle inequality

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Martin Larsson; [2023]
   Keywords : Contraction Hierarchies; Customizable Contraction Hierarchies; Vehicle Routing Problem; Battery Electric Vehicles; Mixed Fleet; Kontraktionshierarkier; Anpassningsbara Kontraktionshierarkier; Ruttplanering; Batteridrivna elfordon; Blandad fordonsflotta;

   Abstract : As the transport industry shifts towards Battery Electric Vehicles (BEVs) the need for accurate route planning rises. BEVs have reduced range compared to traditional fuel based vehicles, and the range can vary greatly depending on ambient conditions and vehicle load. READ MORE

3. 2. When is Electric Freight Cost Competitive? : Computational modeling and simulation of total cost of ownership for electric truck fleets

   University essay from Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

   Author : Anton Zackrisson; [2023]
   Keywords : electric freight; battery-electric trucks; total cost of ownership; decision making under deep uncertainty DMDU ; cost-competitiveness; exploratory modeling and analysis EMA ; EMA workbench; quasi-Monte Carlo method; VRP; EVRP; elektrifiering; godstransport; elektriska lastbilar; total ägandekostnad; kostnadskonkurrenskraft; ruttoptimering;

   Abstract : Battery electric trucks (BETs) offer environmental benefits in terms of reduced carbon emissions and enhanced energy efficiency but have been challenged with economic viability compared to conventional internal combustion engine trucks (ICETs) caused by substantial acquisition costs, limited charging infrastructure, and concerns regarding range and payload capacity.  Previous studies focus on TCO at the vehicle or policy level but overlook the system and firm-level impacts.

4. 3. Optimal Path Planning for Aerial Swarm in Area Exploration

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Johanna Norén; [2022]
   Keywords : Optimization; Path planning; Dynamic programming; Area exploration; Aerial swarm; Multi-agent system; Optimering; Ruttplanering; Dynamisk programmering; Områdesutforskning; Drönarsvärm; Fler-agentsfall;

   Abstract : This thesis presents an approach to solve an optimal path planning problem for a swarm of drones. We optimize and improve information retrieval in area exploration within applications such a ‘Search and Rescue’-missions or reconnaissance missions. For this, dynamic programming has been used as a solving approach for a optimization problem. READ MORE

5. 4. Path and Route Planning for Indoor Monitoring with UAV : An Evaluation of Algorithms for Time-constrained Path and Route Planning in an Indoor Environment with Several Waypoints and Limited Battery Time

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Ola Johansson; [2022]
   Keywords : UAV; path planning; route planning; drone; combinatorial optimization; Ruttplanering; banplanering; vägplanering drönare; kombinatorisk optimisering;

   Abstract : Unmanned flying vehicles (UAVs) are tools that can be used in a variety of scenarios. The most common areas of application are outdoors, where there are not many obstacles to take into consideration when planning a route. READ MORE

6. 5. First Principle Parameter-Based Performance Model for Commercial Turbofan Aircraft

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Jacob Wrase; [2022]
   Keywords : ;

   Abstract : Climate change and greenhouse gas emissions are arguably some of the most pressing threats that today's society has to face. Emissions from the transport sector, including air traffic, play an important role in the pursuit of reducing climate impact. READ MORE
