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

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Sammanfattning : 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. LÄS MER

  3. 2. Estimating Poolability of Transport Demand Using Shipment Encoding : Designing and building a tool that estimates different poolability types of shipment groups using dimensionality reduction.

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Marvin Kërçini; [2023]
    Nyckelord :Poolability; Transport networks; Autoencoder; Dimensionality reduction; Vehicle Routing Problem; Raggruppabilità; Reti di trasporto; Autoencoder; Riduzione della dimensionalità; Vehicle Routing Problem; Poolbarhet; Transportnätverk; Autokodare; Dimensionsreduktion; Fordonsdirigeringsproblem;

    Sammanfattning : Dedicating less transport resources by grouping goods to be shipped together, or pooling as we name it, has a very crucial role in saving costs in transport networks. Nonetheless, it is not so easy to estimate pooling among different groups of shipments or understand why these groups are poolable. LÄS MER

  4. 3. Simulated annealing for Vehicular Ad-hoc Networks

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :ETHISH VENUMBAKKA; [2023]
    Nyckelord :Simulated Annealing; Vehicle Ad Hoc Networks;

    Sammanfattning : In this thesis, we tackle a significant optimization challenge within Vehicular Ad Hoc Networks (VANETs) by employing a simulated annealing approach. We focus on developing an efficient Vehicle Routing Problem (VRP) algorithm to sift through numerous potential solutions and identify the best one. LÄS MER

  5. 4. Transport logistics for a biogas plant : an approach for an optimal collection of manure from local farms by the planned biogas plant Biogas Väst Skaraborg AB

    Master-uppsats, SLU/Dept. of Economics

    Författare :Adam Landelius; William Wejsfelt; [2023]
    Nyckelord :VRP; IRP; VRPB; IRPB; logistics; optimising; biogas;

    Sammanfattning : Vehicle routing problems (VRPs) are a prevalent concern for businesses that rely on effective logistics to collect and transport items. Biogas Väst, a company that collects liquid manure from local farms and returns residue, is facing a VRP that includes both linehaul and backhaul operations. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

    Författare :Anton Zackrisson; [2023]
    Nyckelord :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;

    Sammanfattning : 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.
