  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. Route Planning of Battery Electric Heavy-Duty Commercial Vehicles : Using Contraction Hierarchies and Mixed Integer Programming

    University essay from Uppsala universitet/Datalogi

    Author : Olle Delborg; Elias Insulander; [2023]
    Keywords : route planning; route optimization; contraction hierarchies; mixed integer programming; vehicle routing problem; electric trucks; electric vehicles; battery; openstreetmap; shortest path; Dijkstra;

    Abstract : This thesis addresses route planning of Battery Electric Heavy-Duty Commercial Vehicles to enhance the reliability of electric vehicle transport. Collaborating with Scania, a Swedish truck manufacturing company, the goal is to develop a pipeline that uses open source data from OpenStreetMap and performs a modified Contraction Hierarchy in order to create a graph that can be used as input to a modified Vehicle Routing Problem formulation using Mixed Integer Programming.

  4. 3. On the use of routing engines for dynamic travel time calculation within emergency vehicle transport simulation

    University essay from Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

    Author : Marcus Juninger; Nicholas Narvell; [2023]
    Keywords : Emergency Vehicle Simulation; Routing Engines; Travel Time Calculation; Dynamic Data Generation;

    Abstract : Traditional methods for constructing simulation models can involve severalsteps that require manual pre-processing of large data sets. This process maybe time-consuming and prone to human errors, while also leading to modelsthat are inconvenient to customize for varying simulation scenarios. READ MORE

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

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

    Author : Marvin Kërçini; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 5. 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

    University essay from SLU/Dept. of Economics

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

    Abstract : 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. READ MORE
