  1. 1. 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

  3. 2. 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.

  4. 3. Transportation and Fossil Fuel Use in a Rural Context : A Case Study on Norderön in Jämtland, Sweden

    Kandidat-uppsats, Institutionen för teknik och hållbar utveckling

    Författare :Joakim Lanker; [2012]
    Nyckelord :Rural; transportation; sustainability; accessibility; fuel use; scenario; fossil fuel free; Glesbygd; landsbygd; transport; hållbarhet; tillgänglighet; bränsleförbrukning; scenario; fossilbränslefritt;

    Sammanfattning : The transport sector is facing great challenges of rising transport demand but at the same time meeting requirements of substituting fossil fuels, and mitigating its environmental impacts. Conventional transportation solutions are well-adapted to urban contexts, but not to rural contexts. LÄS MER
