Examensarbete: Model of Construction-Fleet Electrification
Method: Build a System Dynamics model (stock-and-flow, in Vensim or Stella) of a representative major project. Core stocks are machines by fuel type and age; flows are procurement, retirement, and conversion.
Couple three subsystems: fleet turnover, energy supply (charging/grid/battery buffering), and cost/emissions accounting. Calibrate with data from a current project and Trafikverket's climate-requirement schedule, then run scenarios (mandate levels, bonus levels, electricity price) and test policy leverage points with sensitivity analysis.
Om jobbet
Expected results: A validated simulation showing fleet mix, emission, and cost trajectories under alternative policy and price scenarios; identification of the feedback loops and leverage points that most affect the pace of electrification; and quantified thresholds at which electric machines dominate new procurement.
Problem: Trafikverket largest projects span many years, and over that horizon the machine fleets are shifting across three fuel pathways (diesel, HVO100, and electric/zeroemission) at the same time. The transition is governed by interacting factors that unfold over time: fleet age and turnover, on-site charging capacity, grid connection and available power, contractor investment decisions, and the rising climate requirement. A dynamic modelling approach can capture how these factors influence one another and, in turn, how a given mandate or bonus translates into an actual fleet mix, emissions trajectory, and cost path over a project's life.
Kvalifikationer

Ansökan
Detta är en cv-fri rekrytering, dvs helt utan ansökningshandlingar, du söker genom att svara på några frågor. Vi vill däremot att du bifogar ett studieintyg. Om du planerar att genomföra examensarbetet tillsammans med en annan student är det fullt möjligt att söka tillsammans och gemensamt svara på frågorna. Som student har du möjlighet att formulera ett eget förslag på frågeställning i samband med att du skickar in din ansökan. Vi är öppna för att frågeställningen kan justeras senare utifrån synpunkter från till exempel lärosätet.
