1. 16. 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.

3. 17. The Impact of Demand Patterns and Pathfinding Strategies on Payment Channel Networks

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

   Författare :Johanna Löv; [2023]
   Nyckelord :Payment Channel Network; Channel Imbalance; Pathfinding; Demand Pattern; Lightning Network;

   Sammanfattning : Payment Channel Networks (PCNs) provide a solution to the scalability problem in blockchain technology. They facilitate multiple-hop transactions via payment channels between peers, allowing for the execution of several transactions before updating each node’s balance on the blockchain. LÄS MER

4. 18. Spårning av inkommande trafik till anycastnoder

   M1-uppsats, KTH/Medicinteknik och hälsosystem

   Författare :Alexander Petersson; [2022]
   Nyckelord :Domain Name System; Border Gateway Protocol; GeoIP; Anycast routing; Domännamnssystem; Border Gateway Protocol; GeoIP; anycastrouting;

   Sammanfattning : Att en hemsida tar extra lång tid att ladda är inte ovanligt och kan bero på att trafiken från en klient tar en helt annan väg till hemsidans server än den som är geografiskt närmast. Orsaken bakom problemet är att DNS-förfrågningarna färdas onödigt långa sträckor. LÄS MER

5. 19. Randomized heuristic scheduling of electrical distribution network maintenance in spatially clustered balanced zones

   Master-uppsats, KTH/Geoinformatik

   Författare :Carolina Offenbacher; Ellen Thornström; [2022]
   Nyckelord :Capacitated Vehicle Routing Problem; Electrical distribution network; Heuristic algorithm; Scheduling; Handelsresandeproblemet; Eldistributionsnätverk; Heurustik algortim; Schemaläggning;

   Sammanfattning : Reliable electricity distribution systems are crucial; hence, the maintenance of such systems is highly important, and in Sweden strictly regulated. Poorly planned maintenance scheduling leads unnecessary driving which contributes to increased emissions and costs. LÄS MER

7. 20. Modelling and Optimization of Simultaneous Froward- and Reverse Logistics as Capacitated Vehicle Routing Problem : An optimization simulation model problem

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

   Författare :Md Kamrul Islam; [2022]
   Nyckelord :Optimization; Last-mile delivery; VRP; Capacitated Vehicle Routing Problem; Green Vehicle Routing Problem; CO2 emissions.;

   Sammanfattning : Environmental issues are a vital concern in today’s world. The Swedish government and local businesses are developing a sustainable business and eco-friendly environment for city inhabitants. Last-mile pickup and delivery services are a key concern, which significantly impacts the environment and society. LÄS MER
